Re: [SlimDevices: Audiophiles] Garage Conversion - Sound advice ?

2011-02-08 Thread JezA

The rooms only 8' wide, so the speakers can't be much more than 6'
apart. Sitting 12' away would give a very narrow stereo image, which
would be degraded even more by the increased proportion of indirect
sound at that distance, especially as there doesn't seem to be any
plans for room treatment.

Re: [SlimDevices: Audiophiles] Garage Conversion - Sound advice ?

2011-02-08 Thread Phil Leigh

I think Tank needs to say what his expectations are in terms of sound,
because getting a nice sound should be possible, but getting a
great sound won't be possible because of the size of the room and
specifically:
1) available width between speakers
2) proximity of rear wall to listening position
3) likely flutter echo down long dimension (will need stuff on the
walls to break that up
4) likely ratio of reflected to direct sound will be too high

Even without the table/chairs, the room size doesn't quite work IME
because of the 8ft dimension.

you need 1m behind and to the sides of speakers (unless you have
speakers that are designed to work against walls).
IME you need 8-10 feet between spekakers and the same to the listener
you need at least 1m behind the listening position.

If the room is a long-term thing, I'd seriously look at different
(small) speakers...

Changing the streaming method does not solve the problem. And it's not
only affecting very few stations but quite many, especially
talk-radios. What's also interessting, the pitch-shift is not the same
on all affected stations. Some sound higher and faster than others and
in some there are dropouts (sound goes silent for a few seconds). But
it's defenitely connected to the output-mod. As soon as you activate
all outputs the problem's gone. Very strange indeed...

From http://www.rega.co.uk/html/DAC.htm
 Jitter was minimised by synchronously clocking the digital data with our
 receiver PLL (removing any jitter from the input signal).

What I read is: the only jitter in the analog output signal of your DAC
is generated by that DAC and not by your SB, because its jitter was
already removed by the DAC's input stage.

So again, am I missing something?

 If you are looking for sound proofing that's different...

Phil, thanks. I think we're on the same page. I have sloped front and
back walls so I'm planning to wallpaper only the side walls and the
sides of the dormer recess. It should look good too, that way.

And again you're spot on, I'm aiming to fix my nasty flutter echo
rather than soundproof. The bass modes and probably bass RT60 are also
issues and excessive deadening will make things worse.

ATM I have thin blankets draped on the sides. I'm after a lighter touch
than that as long as the flutter echo goes; perhaps regular flock will
do it. The problem is, leaving any significant part of the side walls
bare brings the flutter echo. Given the room is narrow and the walls
are painted plaster board, not surprising.

I believe (but not an expert on this by any means) that the timing issue
(jitter) would be between the digital out of the SB and the digital in
of the DAC, if one is using a DAC.

But I also believe that jitter is an overblown problem and a nonissue
for 99% of us (i.e, it is the boogyman of digital audio). And
certainly not an issue with most SB player users, including the ones
with high end equipment.

stop-spinning;609175 Wrote: 
 Wow - that's some statement I am keen to follow up! When you say modded
 Touch are you talking about software wise or both software and hardware
 wise? How does the stock Touch perform before modification - will it
 still give the Arcam a good hiding before being supercharged? And
 because I started this thread concerned about the quality of the
 digital outs - I am more concerned about just using the Reciever as a
 transport then slapping an appropriate DAC on the end of it (such as a
 Rega DAC) which should subsequently blow a modded Touch of the water
 (if it takes that amount to torpedo it).
 
 I never planned to ever use any SB without external DAC as a true
 audiophile source - I would have throught the priority of the unit
 alone would have been convenience and looks to accommodate the mass
 market - rather than top notch tuned audiophile sound quality. Perhaps
 very good sound quality but not, in stock form at least, 'hi-end' for
 want of a better phrase.

If you follow the steps I'm going to outline below, you will easily
achieve high end audiophile performance on a shoestring budget:

1. Order Beresford Caiman DAC
(http://www.beresford.me/PP/Caiman__DAC.html); it will cost you £179.99
(only $290.00). But before you do that, call Stan Beresford (the genius
behind this amazing DAC, and ask him to Gatorize it for ya (he'll know
what you mean). For additional $50.00, it will be well worth the
effort, because Gatorized Caiman is a ferocious DAC that can compete
shoulder to shoulder with many $2,000+ DACs I've listened to.

2. Order Logitech Squeezebox Touch ($300.00).

3. Connect your Touch to the Caiman DAC.

4. Follow the instructions on this page to the letter:
http://soundcheck-audio.blogspot.com/2011/01/soundchecks-squeezebox-touch-toolbox-20.html

5. Lastly, follow the instructions on this page:
http://soundcheck-audio.blogspot.com/2011/01/soundchecks-tt-beta-blog.html

Voila! For approximately $700.00, and some additional fiddling with the
mods, you'll have a digital player that can easily compete with Linn
Akurate ($8,000 retail). In my opinion, modded Touch fed into Gatorized
Caiman can almost outperform these $5,000+ plus players. All you need to
top it off is a good digital coaxial cable, and a decent pair of analog
interconnects, and no one will be able to wipe the wide idiotic grin
off your face.

As far as unmodded Touch goes, even then you'll notice drastic
improvement in the sound quality, compared to the Duet. I know, I've
been myself through all these upgrades. Started with Duet, ordered
Caiman DAC, then moved to Touch, modded the Touch, and now I'm sitting
in the audio nirvana land.

Well, that IS the only way to really do the whole transport+dac thing

 behind this amazing DAC, and ask him to Gatorize it for ya (he'll know
 what you mean). For additional $50.00, it will be well worth the
 effort, because Gatorized Caiman is a ferocious DAC that can compete
 shoulder to shoulder with many $2,000+ DACs I've listened to.
 
 2. Order Logitech Squeezebox Touch ($300.00).
 
 3. Connect your Touch to the Caiman DAC.
 
 4. Follow the instructions on this page to the letter:
 http://soundcheck-audio.blogspot.com/2011/01/soundchecks-squeezebox-touch-toolbox-20.html
 
 5. Lastly, follow the instructions on this page:
 http://soundcheck-audio.blogspot.com/2011/01/soundchecks-tt-beta-blog.html
 
 Voila! For approximately $700.00, and some additional fiddling with the
 mods, you'll have a digital player that can easily compete with Linn
 Akurate ($8,000 retail). In my opinion, modded Touch fed into Gatorized
 Caiman can almost outperform these $5,000+ plus players. All you need to
 top it off is a good digital coaxial cable, and a decent pair of analog
 interconnects, and no one will be able to wipe the wide idiotic grin
 off your face.
 
 As far as unmodded Touch goes, even then you'll notice drastic
 improvement in the sound quality, compared to the Duet. I know, I've
 been myself through all these upgrades. Started with Duet, ordered
 Caiman DAC, then moved to Touch, modded the Touch, and now I'm sitting
 in the audio nirvana land.

MGC,
I miss the subjective phrases like I hear and preferable sound that
I've seen you use in other posts! This one comes across a bit factual
when this is a subjective matter, to my mind. However, after reading
your post I look forward to hearing a Caiman DAC at some point,
hopefully.

Cheers, Darren

Tank,

This is not a knock on Phil, but by opening up the thread to equipment
suggestions you've basically opened the proverbial Pandora's Box and
now this thread is going to go completely off the rails. There's
absolutely NOTHING that an audiophile likes more than being able to
give their recommendations for audio equipment. These recommendations
almost always consist of equipment from manufacturers that no one,
apart from the audiophile making the recommendation, has ever hear of
and therefore it will almost impossible for you to actually see, let
alone hear, any of the equipment before deciding how to spend your
money. If you don't believe me just sit back and watch. As they say on
a popular beer commercial here in the US: Here We Go!!

Actually I hate doing it!

The speakers I recommended may not be well known outside of the UK (not
sure). There are a myriad of other valid choices, but I would personally
start my auditioning here. They are great speakers - for a room of the
size in question.

You really don't want big woofers exciting the 70Hz first harmonic of
the room without some form of EQ or DRC...best to avoid it in the first
place?

True, but it won't shift certain types of oxidation an dyou can't get

I have a room I need to try this with (Bookshelf speakers up high,
tilted forward, firing down). Any suggestions about what to stick under
the rear of the speakers to create the tilt (that is out of sight). I
vaguely recall seeing a post about some sort of stuff (like a ball of

Try a book or something free to see whether the general effect is
worthwhile. Then you could have a look at Auralex MoPads, used the
'wrong' way round - they'll give you a little possibly useful
decoupling from your shelf as well as a tilt. But it's not much more to
get adjustable speaker brackets - do a google for PMC BRKT-DB1 to see
PMCs offering - or just click this:

http://www.audiot.co.uk/stands-and-brackets/speaker-brackets/pmc/

Plenty alternatives.

Very excited to hear that you (and others) are able to detect
substantial improvements to the quality of sound reproduction through
Caiman. My sound through Duet into the DPA 200s separates and then into
a pair of Maggie planar speakers is already to die for, very hard for me
to imagine how could it possibly get any better!

Take for example the Rega DAC... have you tried taking that for a ride
yet? Once you thought the Duet was great - now you know the Caiman is
great - however just like Touch has killed the Duet - perhaps the Rega
DAC is a Caiman killer? Who knows what's around the corner? Although I
would have thought audio Nirvana is the end of the journey for you. But
wouldn't you like to try just in case?

Re: [SlimDevices: Audiophiles] soundcheck's Touch Toolbox 2.0

2011-02-08 Thread mervin_b

I believe this occurs when the station streams material at lower than
44.1kHz sampling rate (note - not bit rate), and the asound.conf from
the toolbox.

I have a workaround, not tested enough to be declared a solution yet:

# /etc/asound.conf for digital out only:
pcm.digital {
type hw;
card TXRX;
}
ctl.digital {
type hw;
card TXRX;
}

pcm.!default digital

# mod of mod to support non-hardware sample rates:

pcm.digital {
type plug
slave {
pcm hw:0,0
}

# rest is un-changed (but still needed!)

Reboot to make the change effective.

This uses the plughw driver which will resample when needed, but afaik
there will be no effect when 44.1, 48, 88.2, 96kHz audio is sent to
alsa.

Regards.

 I just had an idea. Could you do me a favour.
 
 Does the chipmonk effect disappaers if you:

Re: [SlimDevices: Audiophiles] Rebooting your audio system

2011-02-08 Thread gizek

 
 Others have pointed out that the improvement may have been the result
 of clean connections from unplugging  replugging cables. But it may
 have also been the culmination of various unconscious influences that
 day. Some you might be able to understand (getting your good sound
 back was a great relief) but other things might be more difficult to
 spot and sort. 
 

Very true indeed. Sometimes we need to reboot our audio systems, other
times it is our brain which needs resetting.
In my, over a quarter of the century long history of being audiophool,
I very often found myself improving audio system only to wake up the
next morning and set everything back to the original state. I try to
keep the idea of the music as fresh as possible, regularly visiting
local symphony and concerts. Yet, still it's very hard to obtain the
same, satisfying results in my listening room. It is never ending game
with countless number of changing rules. Making things worse, there is
some irony here,  through all of those years of ear training, I've
discover that my wive and my cat are much better listener than me in
the sense of being able to formulate better, objective
judgments(reactions) whether my system is capable of reproducing
natural sound or not.

Re: [SlimDevices: Audiophiles] soundcheck's Touch Toolbox 2.0

2011-02-08 Thread soundcheck

@mervin_b

I guess, you got it.

I just looked into it. As a matter of fact. The default outputs are
configured as hw devices. 
However, the merger of the outputs is done via type plug. ( Which is
the so called plugin layer of Linux/Alsa)

Choosing the plugin layer as output type under Linux is the 2nd best
choice when it comes soundquality.


My conclusion would be, that people who run into that chipmonk issue
and can't live with it, skip the ttout mod. 
Because changing the output as recommended by mervin_b would slightly
degrade the SQ again. You'd end up at a very similar level,  if not the
same ,  as with the original setting.
