Re: [SlimDevices: Audiophiles] Inguz on Vortexbox Appliance

2011-10-11 Thread esbrewer

The thing that really kills me about Inguz DRC is the fact that the
command prompt based install for Mac OS "breaks" with each SBS update
and needs to be redone.

In addition, the threads describing edits several (dedicated and
generous) members of this forum have made to the Inguz DRC files to
keep them operational with the newer versions of SBS are often
difficult to follow and replicate.

Does any former Inguz DRC user have experience with the BruteFir plugin
- particularly with VortexBox?  Would the BruteFir install break with
updates as the Inguz Mac OS version did?

The Studio 20s definitely run a bit hot on the high end.  Not for
everyone, but definitely works for me.  The PMCs have always interested
me, I've read several reviews suggesting the transmission line design
might not be the best option when placing speakers so close to room
boundaries.

The active v. passive discussion is interesting - but frustrates me in
that are the active market is so limited to date.  I agree that the
companies have to do a better job of committing to and selling active
technology.  If Paradigm gave up on it after a year or two it doesn't
bode well for smaller firms.

Regarding my original question to the group - there seems to be little
support for the 1996 to 2011 entry level monitor upgrade.  Given that
I'm not willing to make the aesthetic changes to accommodate a larger
monitor or a floorstander or spend considerably more to put a higher
end speaker in a compromised location - I think I may hold off a bit
longer.

A new, dedicated listening room would be nice...

So if I need my really need my "boxes ticked" I should look for a
change - interesting...

I suppose Phil is right in that it makes some sense to try something
different with a new speaker purchase - except that my experience with
my current speakers has been so positive.  I really haven't experienced
a profound desire to upgrade until now. This whole decision would be so
much easier if one of my current speakers were to show audible signs of
their age or fail outright.

I have looked into ProAc several times - but a few US east coast
dealers seem to have dropped the brand recently.  Same experience with
Tannoy (Revolution Signature DC4s look particularly interesting).

My SVS sub is amazing by the way - musical, adjustable, affordable,
built like a tank and relatively inconspicuous as subs go.  With that
sub in place and the Inguz corrections the mini-monitor path is
perfectly appropriate for me.

The Dalis and Meridians look promising but are probably a bit out of

To bring this back to my basic question however - has anyone here
upgraded from a well designed monitor to a newer version within the
same (or similar line) and seen huge improvements?  incremental
improvements?  no improvements - or worse?

The optimist in me wants to spend, the pessimist sees diminished

Agreed on the Sonus Faber - perhaps a bit overpriced but everything

The active speakers clearly bring some advantages but many of them (at
least on the affordable end) are not my taste - LEDs, knobs, and no
grilles.  I wish more manufacturers (particularly those based in North
America) would simply offer active and passive versions of speakers
with similar aesthetics - or take the modular approach to crossovers
like Linn.  I almost purchased a active Linn Tukan based system when I
bought the Paradigm Studio 20s I'm looking to replace.  They were tiny
speakers and sounded brilliant - just no real bass to speak of.

I guess the last paragraph here gets to the core of my question - how
do all of these advancements manifest in the quality of the sound
produced by a modern monitor? Let's assume companies like PSB, Paradigm
and Dynaudio do significant R&D and use new technologies to improve and
refine their designs.  Does this effort result in subtle improvements -
or something more significant?  Care to elaborate on a modern design
that you might expect to perform poorly on site?

The MMGs would be high on my list if not for 3.5 year old child and

[SlimDevices: Audiophiles] speaker advancements over 15 years?

2011-07-01 Thread esbrewer

I am considering replacing my Paradigm Studio 20s (v1 - from around 1996
or so).  Primary motivation is to move to something smaller as speakers
are mounted on bookshelves by necessity - trying to free up more space
and reduce "presence" of electronics in the room.  Secondary (but
strong) motivation is simply to purchase something shiny and new to
replace aging equipment.

My dilemma - I am (and always have been) very satisfied with these
speakers.  Inguz DRC and a competent subwoofer are able to compensate
to a significant degree for the less than ideal speaker placement.

My question - what improvements am I likely to see from a well
designed, constructed reviewed monitor from 2011 as compared to the
same from 1996?  I know the easy answer is go listen for myself, but
given the importance of location and Inguz in my setup that is easier
said than done.

Considering the Paradigm Studio 10, PSB Imagine Mini, KEF Q100 and
Dynaudio X12.  The Studio 10s have the additional advantage of being
front ported.

Thoughts?

Re: [SlimDevices: Audiophiles] very useful Foobar plugin....

2011-04-18 Thread esbrewer

So this plugin will tell me to what degree many recordings I love have
been more or less ruined by mastering?  Interesting project if it had
the potential to better inform the public, but I'm afraid that average
person knowledgeable (and patient?) enough to seek out foobar and its
associated plugins is already painfully familiar with the problem at
hand.

Too much information perhaps?

I do remember reading a great article by Bob Katz about a DR scale (or
something similar) that identified a select list of properly mastered
pop and rock recordings.  He even pointed out that some relatively
"loud" recordings can still offer decent dynamics.  I think he cited
Rage Against the Machine's self-titled recording and John Mellencamp's
"Whenever we Wanted" as popular examples of works that can make both
sides of this argument happy.  In my experience they both sound great.

Keep searching and you'll find the threads.  I don't have a good handle

It works great, but I just got tired of tweaking everything in response

which thread contains the correct modification to the plugin files is
required to keep things working.  It just required more effort than I'm

Currently considering giving a hardware based solution like the KRK

I'll assume you have followed the instructions Muski posted on these

to the plugin files with the recent changes to SBS.

I had a problem similar to what you are experiencing, and the issue
came down to permission restrictions on the folders inside the

that they are not too restrictive.

Re: [SlimDevices: Audiophiles] Confused between options - any advice welcome

2010-07-09 Thread esbrewer

One thing to consider is that many of the more affordable active options
on the market are just not pleasant to look at.  I'll assume given the
price range of the equipment in your system (very similar to my own)
that the higher end active gear (ex. ATC) is not a consideration here.

I have considered going the active route for a while to make my system
less conspicuous - but always find that the homely active monitors with
their visible lights and controls, and/or stylized drivers defeat the
purpose.  Why don't they offer grilles for these things - even as an
option?

Re: [SlimDevices: Audiophiles] Confused between options - any advice welcome

Using one of the room correction options out there can bring significant
improvements for very little cost - particularly for LF issues.  Give
Inguz or Brutefir a try.  The KRK Ergo is an affordable option as well.

Re: [SlimDevices: Audiophiles] 2.0 vs 2.1

2010-05-22 Thread esbrewer

The biggest advantage I have found to using a sub is you have greater
flexibility in placing discrete LF drivers in a location where they
will best interact with the room.  The trade off is increased
complexity - and the subsequent experimentation with (and obsession
with?) measurement and adjustments to phase, gain, placement, xover
points, etc.  Inguz DRC has done a great job in taming the additional
energy a sub has brought to my modest system - but DRC has an
significant learning curve of its own.

Re: [SlimDevices: Audiophiles] Inguz results

2010-05-21 Thread esbrewer

I actually did identify the curves in the text of my post - you must
have missed it.

I considered trying to restrict the function of Inguz to the LFs as
well, but haven't really noticed bothersome artifacts going full
range.

I'm hoping to take another set of measurements soon to see how closely
the real corrected response corresponds to the test convolutions
generated by Inguz.  I recall reading in some earlier threads that the
test convolutions can be misleading.

Another interesting question - is such a flat response actually
desirable?  It gives great resolution of details - but sometimes sounds
a bit too controlled or flat particularly with very compressed
recordings.  Is the uneven response you might have in a particular
venue part of what makes the sound compelling - or is it solely the
dynamics of the live performance?

Considering the issues with the speaker placement, furniture position,
and opening to the adjacent room I thought it was pretty impressive
result and worth sharing.  I'm hoping more people will give it a try -
definitely beats spending lots of cash on equipment upgrades.

Re: [SlimDevices: Audiophiles] How to fight clipping due to high (recorded) volume?

2010-05-19 Thread esbrewer

Spend your money elsewhere.  I actually returned a few CDs in the mid
90s when this loudness garbage first started - thinking they were
defective.  I finally learned 5-6 years back that these products are
actually defective by design.  Its sad - but they really have ruined
some very good music for those of us that care about the sound quality.
Every informed article I have read on this topic says there is
absolutely nothing you can do do repair the damage done during
mastering.

One would think they would see an additional marketing opportunity in
selling "audiophile" versions of their recordings thru select vendors
at a premium price - but no luck no far.

[SlimDevices: Audiophiles] Inguz results

2010-05-18 Thread esbrewer

For anyone that is considering using Inguz or other methods of DRC -
here are some recent results.

Green curve - measured impulse response.  Blue curve - test convolution
for minimal correction.  Red curve - test convolution for normal
correction.  Target curve was a flat response.  Measured using MAudio
MobilePre and Behringer ECM8000.  Note less than ideal speaker
placement due to strong dog and young child.

I prefer a flatter response, but I have had good results with putting a
gradual cut on the HF as well using a different target.  Definitely not
a flattering setup for overly bright recordings - but works great
overall.  Taming of the LF response is a huge benefit.

Sorry if the pics are too much - but I thought this was a good look at
what can be done with a modest system and a small investment in
measuring equipment.

Re: [SlimDevices: Audiophiles] RC (Inguz etc.)

2010-05-02 Thread esbrewer

A few threads started immediately after the release of 7.5 about
problems with playing apple lossless files.  Apparently a shift to (or
away from - my head was starting to hurt following these threads) a
utility named faad has changed the way apple lossless is processed by
SBS.

I tried to install Inguz again under SBS 7.5.  Everything went as
expected, but then I found no Inguz options for apple lossless or AAC
in the File Types menu.  All of the other Inguz options were present. 
Most of my library is in apple lossless to make the use of iPods more
convenient via iTunes.  Does this mean my run with Inguz is coming to
an end?  Reverting back to older SBS versions is not really an option
as I plan on purchasing a Touch sometime soon.  I also don't want to
mess with SBS too much as I use a Boom as my alarm clock and need
stability there.

Keep in mind that the "effects" may actually be positive.  There seem
to be valid arguments in both the full range DRC and LF only DRC
approaches.  Dismissing one approach without hearing it work in your
particular situation seems limiting.  Give both methods a try and see
which one actually sounds best - intellectual concerns aside.

Re: [SlimDevices: Audiophiles] RC (Inguz etc.)

2010-04-09 Thread esbrewer

If you search around here you'll find many experienced users of Inguz
DRC that consider it a crucial component in their systems.  That being
said, there is a steep learning curve and frustration at the beginning
is part of the process.  I have been using it for several years and
seem to get better outcomes each time I use it.  If you have to place
speakers in a less than ideal location for practical reasons as I do it
can be a tremendous benefit.

It will effectively correct bass issues - but in my experience this can
sometimes reduce the impact of some recordings.  It took me some time to
realize this, but sometimes that uneven measured LF response we hate to
see is simply part of what we expect from certain types of music and
venues.  I've heard more than a few DRC users complain that the process
"takes their bass away."  For example, the gentle LF rolloff Inguz often
gives me makes bass guitar lines much more definition, but sometimes
reduces the kick of a bass drum.  I generally am willing to accept the
modest compromise, but sometimes turn off Inguz when I feel things are
sounding too "controlled".  The other option Inguz offers is a flatness
control that allows you add back in some of the defects you've worked so
hard to correct.  Its funny how you reach for it after all the effort.

Re: [SlimDevices: Audiophiles] Aperion Speakers & Peachtree

2010-03-28 Thread esbrewer

I would imagine very few people in this forum are going to recommend a
tower to someone looking in the $1000 range for loudspeakers.  The best
values on that end of the market (and the market in general) are 2 way
monitors.  If you're going with the towers because the aesthetics of
stands don't work for you, your options are more limited.  If you're
going with the towers to get greater LF extension, then a 2 way
mini-monitor with a modest subwoofer gives you more flexibility. 
Brands like PSB, Paradigm, Dynaudio, NHT, B&W all offer great values in
the $1000 range.  All of these brands are relatively easy to find and
would represent a significant step up for you.

The Peachtree looks very like a great option.  I've been thinking about
picking one up to to pair with some Paradigm Studio 10s or Dynaudio X12s
to reduce the bulk of my present system a bit.

Since you mention REL, they actually recommend the use of speaker level
connections with a very low xover point.  The argument is that timing
cues and the character of your amp will be picked up by the sub. Not
sure how that helps you though, as I assume the active speakers have
digital inputs direct from source.

My SVS sub is compact, well suited to music, adjustable via parametric
eq, and built in the US.  Very happy with it.

[SlimDevices: Audiophiles] mini monitor dilemma

2009-08-31 Thread esbrewer

I have used Paradigm Studio 20s (v.1) for about 14 years.  I am still
very happy with their performance.  However, as a practical matter they
must be mounted in bookcases (ports plugged) on either side of a
fireplace.  I understand this placement is less than ideal, but I am
able to use Inguz DRC to correct to some degree.

I would like to find a smaller speaker to replace the aging Studio 20s
so that I can rearrange the shelves make additional room for books to
stand upright.  It is the height of the Studio 20s causing the problem.

Questions:

1.  Does anyone have experience with a front ported or sealed mini
monitor (12" high or smaller) that would roughly match or exceed the
Studio 20s performance? Right now it seems the new Paradigm Studio 10s
would be a great place to start - but I'd like to investigate other
manufacturers as well.

2.  Or, am I wasting the potential of a quality mid-level monitor with
the bookcase placement, and therefore should I save cash and step down
into more of a budget level monitor (ex. Paradigm Atom Monitor?) letting
my subwoofer handle a slighter greater load? Has anyone here stepped
down in a similar way and felt comfortable with the decision?

Re: [SlimDevices: Audiophiles] Subwoofers from a high-end perspective?

2009-08-28 Thread esbrewer

I agree that many audiophiles dismiss subwoofers without actually trying
them for several reasons:

1.  Buyer's remorse regarding the use of a high pass filter that
actually cuts signal from speakers they've made a significant financial
and intellectual investment in.

2.  Many subwoofer installations (particularly in theater setups) have
the gain and crossover set way too high.

3.  Room issues rarely get the attention they deserve, and become even
more obvious with integration of a sub into a system.

4.  Sometimes the extreme LF in a recording is absent, of poor quality
and/or simply distracting - and perhaps best ignored.

I have learned the following in using several different subs in my
modest system 2 channel system over the years:

1.  Smaller sealed boxes with parametric EQ are much easier to
integrate into a system than larger ported boxes - as they are easier to
place in best location.

2.  The benefits of the high-pass filter on midrange clarity and
dynamics are very real, and well worth some of the artifacts the
crossover might impose.

3.  DRC tools (like Inguz) can be particularly beneficial to subwoofer
integration, as it can tame some of the nasty nodes and resonances that
plague our rooms and are excited by LF energy.

4.  Keep the crossover point set comfortably below the +/- 2db rolloff
point for the monitors.  A gap in response is preferable to an overlap.

5.  Phase adjustments rarely seem to have a significant impact - you
can measure them with a meter, but their effect is subtle at best.

Re: [SlimDevices: Audiophiles] Inguz dsp plugin - what are the results?

Inguz will run on newer Macs but there is no installer package for Mac
last I checked.  I was able to follow some instructions posted by muski
on the Inguz forum that use the console to run the install.  Certainly
not the easiest way to do things - but you get used to it.  Search the
Inguz forum for muski's document and give it a try.

I don't recall seeing too many people complaining on any of these boards

processor a bit.  Most people here are more qualified than me to answer
your workaround question, but I would think the only way to really see

Re: [SlimDevices: Audiophiles] Inguz dsp plugin - what are the results?

2009-02-14 Thread esbrewer

Excellent results here overall - I've been using it for a couple years. 
Inguz has saved me a ton of cash in avoiding equipment upgrades with
significant diminishing returns.  I have to keep my speakers mounted in
bookcases for protection from my daughter and large dog, and Inguz
allows be to make the best of the less than ideal placement.

I should also say I have gotten away with using Inguz on a relatively
low powered PC (1.1 Athlon 768MB RAM or so) streaming lossless to 2
SB3s simultaneously with no stuttering whatsoever.  I currently run
Inguz on an Intel iMac w 2MB RAM - and rarely quit the 4-5 other apps I
regularly use with no apparent lags whatsoever.

The few frustrating experiences I've had have come with upgrades, as
the installs on the Mac have to be done manually using the console, and
part of the setup breaks with each change.  It's tedious - but really
doesn't take more than a few minutes - I shouldn't complain.

It would be really cool if the silverlight web interface in
squeezecenter was more useful - but that hasn't ever really worked for
me.  Could be a Mac thing.

Bottom line is I can't think of a more cost effective way to improve a
system.

I think the fact that Paradigm bailed on this market niche says a lot.
They have clearly figured out a way to manufacture quality equipment in
North America at a variety of price points.

Perhaps they made the push toward active speakers prematurely, but it
still really hurts not to have a market leader putting product on the
shelves to see, hear and touch.

I'm glad someone mentioned ATC here.  It would be nice to see them
offer some more affordable products (and something a bit smaller in
scale) - but as with AVI they're not the easiest things to find for an
audition in many parts of North America.

Many people seem to happy with the performance of these products - but
why do so many of them have to be eyesores?  I understand that many of
them are designed for near-field studio use - but one would think that
having attractive products would make the studio a more pleasant place
to work.

The Audioengine A2s in my daughter's room have beautifully designed and
constructed cabinets - but they would be much less conspicuous with
grilles - which aren't even offered as an option to the best of by
knowledge.  I would love to see more loudspeaker manufacturers bring
traditional looking, affordable active monitors to the market.  I know
Paradigm produced an active line years ago that critics seemed to love,
but they dropped the line shortly thereafter - presumably due to
lackluster sales.

Can anyone recommend a line of traditional looking small active
monitors - with quality cabinetry and no gaudy lights, switches, etc on
the front panel? Couldn't they expand their market a bit by simply
offering optional grilles?

Re: [SlimDevices: Audiophiles] room correction / EQ is awesome!

2008-08-26 Thread esbrewer

I agree completely with the positive impacts DRC can have on a system -
especially if the speaker locations are less than optimal.

I have a pair of rear ported Paradigm Studio 20s (from 1996 or so)
mounted inside bookcases on either side of a brick fireplace to protect
them from my daughter and bullmastiff.  Despite the less than ideal
location for any speaker, particularly rear ported monitors, the
quality of the sound I get using DRC is amazing.  I was looking for an
excuse for years to upgrade/replace the Studio 20s (which I still love,
but they've been with me for long time), but DRC has made me reconsider.
Now that we can correct for some of the rooms interactions so easily
using DRC, are upgrades from "entry-level" well designed and
constructed loudspeakers really going to deliver significant returns?

The only significant limitation I've found with DRC is the reduction in
volume.  My amplifier is already a little underpowered - and the need to
take Inguz prefs back to -18dB or -19dB has taken a small amount of the
fun out of higher volume listening.  But with an infant in the house,
how often will I really be able to crank things up anyway.

Quality entry level audiophile speakers are so easy to find these days
- mathcing them with DRC is a no brainer.

Re: [SlimDevices: Audiophiles] Χ Ο Δ Ε (CODE) format

I personally think Mellencamp is a great choice for something like this.
He sells a lot of records, and has a history of releasing
well-engineered recordings - despite the loudness race etc.  In
addition, a small but significant portion of his audience (at this
stage in his career) might actually be concerned about sound quality.

If Burnett were to have debuted this stuff with an emerging pop or rock
artist - no one would have cared.  And I think asking people to buy yet
another remastering of a classic recording is getting long in the
tooth.

When artists that other artists respect become early adopters of new
technology, such technologies have a better chance of taking hold.

I just wish I could play the hi-res version of this recording with my
SB3.  I really enjoy it, and based on the generally positive reviews
its getting I'm apparently not alone.

I'm not sure I follow the reasoning here.  

If iTunes and other less secure rippers popular with the general public

Just noticed (after finally doing some listening after all this grunt
work) that the HF response in the right channel only is way down - to
the point where I thought I had possibly blown a tweeter running the
sweeps.

When set DRC to "None" - the HF comes right back to the right speaker. 
Perhaps the graphs I posted are showing the left channel only, and the
right truly is way down?

The question is, why would the one channel be lacking HF?  The sweeps
sounded normal as I ran them.

I ran new measurements without the sub in my system, and the large dip
around 130hz went away.  The crossover must have been doing something
odd - thanks for pointing me in the right direction guys.

But DRC is still not acting on the upward trend in the HF.  Attached
are my new measurements (measured response, minimal, normal, insane). 
Any suggestions as to why?

A couple of you appear to be suggesting (and correct me if I'm wrong)
that the ecm8000 file is NOT being considered in the generation of the
test convolutions.  Does that mean that DRC may be actually correcting
for the HF upkick in what I hear, but the test convolution responses
may not show it?

If so, are the test convolutions really useful in assessing how DRC is
working?  I assume then that the only way to TRULY measure the DRC
impact on our systems is to take new measurements with the filter on?

I believe all of my .drc files refer to the ecm8000 correction file.  I
suppose that could have changed with a reinstall, I will check.

I checked the pspoints file, and it is indeed set to the bk-3-spline
target.  I have no explanation as to why DRC is allowing the HF
increase to remain. It is my understanding that the HFs are rolled off
to varying degrees in the bk target files. I've been reading posts
suggesting the ecm8000 (which I used) can be inaccurate in the HF
ranges - could this be contributing to that uncorrected upturn?

I also noticed the normal test convolution looked too "severe", so I
have attached a new graph of my measured response (red), minimal
(green), normal (blue), and insane (purple) test convolutions.  Why
would the differences be so subtle? Inguz looked at one of my earlier
(different) sets of measurements and commented that I was getting an
extremely linear response (especially through the mid range) and
guessed that I was using a relatively high quality small monitor in a
relatively "active" room.

Thanks for the input.

My Paradigm Studio 20s run off the high pass out of a B&W ASW600 sub. 
It sounds reasonable that the crossover may be causing that nasty dip
at 130, and contributing to the clipping problem.  I guess I'm asking
DRC to make too large a correction in that area.

The Studio 20s cannot be moved from bookshelves flanking a fireplace
location - as the shelving protects them from a sweet but solidly built
Bullmastiff - although the bookshelves themselves could stand to be
raised a few inches.

I'm looking forward to trying measurements without the sub, as it
appears it may be doing more harm than good.

I will look into the overly flat normal convolution curve as well.  It
does seem to be a bit aggressive for what was indeed the normal
correction file.

I played with REQW and think I have my impulse response measured and
normal test convolution file in a form you can all get a good look at. 
These measurements were generated using a flat target file.

As I mentioned earlier in the thread, Inguz DRC has improved my system
dramatically, but I'm forced to move up to -23db to avoid clipping on
louder cds.  It also seems (to my ears) that DRC exaggerates the
already compressed sound of some of these cds.  Any thoughts on what I
might be hearing?

If I did this right, the measured impulse response is in red, and
normal test convolution is in green.

Sorry for the delay.  I got REQW and converted the one file using
Goldwave as suggested.  I would love to post the files to get some

to get my impulses into a postable visual format?  I really don't want
anyone to waste their time tutoring me on the ins and outs of REQW, but
at the same time I'm curious to get some feedback from you all.

If the only practical way for me to post is just buckle down and learn
REQW myself say so, and I'll try to find some time.

Re: [SlimDevices: Audiophiles] First shot at using Inguz

2007-09-21 Thread esbrewer

I'd be happy to post the files, but I'm not quite sure exactly which
files you're referring to, and what form (if any) they need to be
converted to to be viewable.  I really just followed Inguz's
instructions to the letter to set things up - but don't truly
understand what each component of the Inguz system actually is.

Is the measured impulse response the file that ImpulsePrep created for
me from my recordings?  If so, isn't that a sound file?  Do I have to
capture an "image" of it to post?

And the filter file - are those the files that give me the option of
"normal, strong, minimal" room correction?  If so, I've been using the
normal one almost exclusively.

I believe the last target file I used to generate impulses was the
bk-3.txt file.

The few (and they are few) flaws in the implementation of Inguz DRC for
me may come down to the integration of a sub in my system.  Perhaps
there is a dip in my LF response that is causing DRC to try to boost
more than is healthy - hence the need to drop down to -20db and still
clip on loud recordings.  One of these days I'm going to try DRC
without the sub - but I just don't have the patience right now to
reroute all the cables and remeasure.  When I do, I'll probably find I
don't need the sub at all.  For now, a large bullmastiff dog requires
me to keep my speakers mounted on bookshelves.  Using the hi-pass out
on the sub to run the speakers seems to cut down on some rattles and
shakes with stuff on the shelves, and clears up the mids a bit.

My modest system includes (pic posted in photo thread):

Paradigm Studio 20s (running off sub hi-pass filter)
B&W ASW600 subwoofer (running off speaker level)
NAD C720BEE
NAD C542
SB3

Sorry for my lack of technical expertise here.  This is all probably
more than you wanted to know, but if we all didn't find this stuff
interesting we wouldn't be posting here.

Re: [SlimDevices: Audiophiles] First shot at using Inguz

2007-09-21 Thread esbrewer

I'm with mortod on focusing on notch filters rather than boost (maybe as
an option?).  Inguz DRC has dramatically improved my system, but
clipping does become a problem.  I am at -20db right now, and still
have significant clipping due to many newer recordings being mastered
too loud.  My amplifier doesn't have much power to spare, and every db
I lose to avoid DRC clipping is one I'd rather not throw away.

Everyone contributing to this thread has a greater command of technical
aspects of DRC than I do (I've probably failing to understand something
as I write this), but it does seem to me as if DRC further dulls the
already flat, compressed sound of newer recordings.  For recordings
that are mastered and compressed properly, Inguz DRC is amazing.  For
those that are not (the most recent U2 recordings come to mind), I
sometimes avoid DRC and power up my CD player.  But perhaps all of this
simply comes back to the "garbage in, garbage out" type argument - if
they would only stop ruining recordings to make them sound good in our
cars...

Do my perceptions here make any sense?

Its funny - but I hadn't even noticed what was playing at the time I
finally got around to taking some photos of my setup.

I was fortunate enough to hear him perform live 6 or 7 times.  In the
time since his death, I'm sorry to say that I don't listen to his work
as much as I used to.  His recordings are all so different, and I'm
realizing listening to them always left me eager to hear more work yet
to come.
