Re: [SlimDevices: Audiophiles] powered monitor recommendations

2008-12-07 Thread eiret

The Quads are are too reaviling. If you listen to radio/mp3`s in office.
Some songs are good though, but you have to listen to some bad ones,
unfortunately.

You need a Transporter/DAC1(flac,wav) or simular i think, to make them
sound good.
For the time being i havent had the pleasure to try it out. Its a
theory.

Who knows. Maybe noice. Has somebody tried with a SAS - SCASI(or
something)?
A good cd player drive is how fast? Why? 
There are 1 or 2 engineers known for making very good cd player drives,
i have read on the internet somewhwer a while ago. Maybe they can make a
very good harddrive? 
Just my 2 cents of late night thinking. It is a market for 50 terrabyte

Its not an absolute claim: A harddrive can have a bad influence of the
sound. That is on of many reasons we use streaming boxes, i think. It
may be a difference between a Seagate or Western digital or betwee the

I have read that the CPU plug/psu on the motherboard(not he on at the

Millions of transistors tapping up and down. More expensive motherboard

I dont think it is a problem with todays computers/SB/DAC/soundcards.
Especially not when connected wia ethernet. This post is also an excuse
not to do the whasing-up(kitchen) yet, but later.

In a 4-5 weeks time, i will "maybe" try SB3 digital in to a soundcard

difficult to find English software to this soundcard. English driver

Since you can have two computers, cd player etc connected and switch

Or others are free to answer.

Is it right to say: When a analog wave, from for example a microphone
is discovered by the ADC(analog to digital converter) the wave is first
sampled/discovered as a 1bit audio. Then up sampled to for example
24bit?

Asking this because the DSD format is 1bit/2.8224MHz. The word length
is 1bit? 
Do sound engineer`s uppsample to 24bit primary to be able to use more
tracks, equalisation etc when recording?

Quoted from this tread.

EliasGwin Appliction enginner.

The analog inputs of the DAC1 PRE are routed to both the unbalanced RCA
outputs and the balanced XLR outputs.

The main differences between the DAC1 PRE and the DAC1 USB:

-DAC1 PRE has 5 digital inputs (USB, optical, coax(x3))
-DAC1 USB has 4 digital inputs (USB, optical, coax(x1), and XLR)
-DAC1 PRE uses teflon chassis-mounted RCA analog and digital
connectors
-DAC1 USB uses PCB mounted RCA connectors
-DAC1 PRE has 3 gain ranges for the HPA2 headphone amplifier
-DAC1 USB has 2 gain ranges for the HPA2 headphone amplifier
-DAC1 PRE uses National Instrument LM4562 opamps throughout the analog
circuits
-DAC1 USB uses 5532's every except the output drivers, which uses the
4562's
-DAC1 PRE has power button
-DAC1 USB does not have power button

On the rear panel to the left DA1 PRE has a button switch control. You
can switch between Output level-Calibrated, Mute, Variable.

>What about balanced outputs, fixed or variable?

I think a user have the possibility of selecting this.

> Can the analog audio input be passed out through balanced outputs?

There are two analog outputs. I hope it does.

> In my experience, if one wants to go with the external DAC, than it's
worth exploring the possibility to delete the preamp. And (again in my

usability.

It deletes the need for a preamp. DAC1 PRE has a analog volume control.

Suggestion for attenuation. Have noe expirence with it my self, but i

If your point is right you are not missing something.

I do not have the gift to remember everything i read. Thats why i am
discussing it(digital vs analog volum) here in this fourm whre there
are peaple with more education, training.

Using "my" calculator. Multiply 16bit decimal value 65535 with
0,35(%error) and converting it back to binary it only affect the last
bit. Just likes as you explained.

The higher wordlength and sample rate we have the less potential error
distortion we get, when reproducing analog audio. If the uppsampling
device is very good, or the audio line are correctly implemented -
computer - software - dac - dac - amp - speakers.

If you add wordlength and sample rate it can couse to much peak and
distortion to treble and bass. Potentially.

Every time we are using digital volumecontrol, i quote from the
guide(dont know if it is allowed?): To apply gain or attenuation to a
digital audio signal, a multiplication is performed on each digital
sample that collectively create the digital audio signal.

If we use 24bit/96khz in todays audio, we stays within the potential of
0,5% error, presumably. And only the last digit will be affected. 

But, if that is not trough ? I dont know. 

Peaple cant hear no difference. Transporter use digital volume(it must
be good). I will use the analog volume and recommend the other users in
this apartment to also use analog volumecontrol later. It is nice to
know that software player - SB3 - is at 100% volum.

It have being interesting and fun to discuss.

The point is, there doesn't seem to be ANY real difference between
analogue and digital volume controls, even in principle.  

opaqueice,

I am interested in your meaning after reading the guide.
If you have time, please read trough this section of this guide :
Digital volumecontrols.
http://extra.benchmarkmedia.com/wiki/index.php/Digital_volume_control

A little quote form the guide :Disasterous distortion can potentially
arise when a digital volume control is implemented

Binary numbers, just like decimal numbers, do not always multiply and
divide evenly. There are often remainders - extra digits that are a
result of the multiplication.

Interesting question and reflection.

Maybe the digital volumecontrol stuff is a red herring.
>From an amateur audio filosopher point of veiw there was meaningful to
mention that it is measurable mathematically, an decrease in audio
quality when using digital volumecontrol. Even though you cant hear it.
Thats how i express it after reading the guide linked in an earlier
post.

There are peaple that prefer analog volumecontrol and those who dont.
The same with proffessinoal audio producers(both analog and digital). 

If the transporter have digital volumecontrol ? Maybe it is bechause
the digital is good enouhg ?

It would be fine to have a final conclusion : Does digital
volumecontrol resoult in decrease in audioquality ?

Is it just measurable mathematically ?

As i pointed out before. Maybe not audible. It is measureable
mathematically according to the guide that was linked in my post. It
can be more than 1 bit and sample rates, or just maybe only loss of
sample rates ?

>Anyway, as you obviously seem to think that Benchmark wrote the book

I will.

If some engineers write a guide(if they are)under benchmarks name, i
think they know what they are talking about. I am an amateur who like
to read guides, so i can get some knowledge.

There are also other good dac`s out there, and guides too.

The experts are here
http://extra.benchmarkmedia.com/wiki/index.php/Main_Page
I think they are making reference to finished recordings. CD, DVD,
Computer Audio Playback - wav, flac...not during the acutal producing
of the master tapes. Some prefer analog volume control in studio too, i
think(not being in a studio). 

You are quiet right regarding digital volumecontrol in studio. For the
most of them. 

It is measureable mathematically that analog is better on the finished
product. That said, i am bad in math(thats why i am refering to
experts).

I am using SB3 directly in to Quad 12l Active and are quiet happy my
self, listening to music. I will use analog volume control later.

BUT, i will use analog volume control when i eventually get one. Just
to get the best audio quality mathematical binary thinking. 

It is measurable mathematically.
But that is not the same as saying it is audible, that you can hear it.
Maybe you must have an $200 000 equipment to hear the difference.

It IS measurable. Something to do with the binary 2 - number system. It
cant be as accurat as 10 - number system. I forgot my earlier reading.

I am not an audiophile, i post here anyway.
Experts recommend analog volum control and digital volum set to 100%.
You are all agree about that i think. Since you cant hear any decrease
in audio quality when using digital volume compare to analog volum
control, i think we are using 24 or 16 bit all the time(16/24bit
recording). 

Bechause i think we need all the bits anyway if we are using 40% volum
or 90% volum. This is an 8 bit example :
00101000 = 40% volum01011010 = 90% volum To me, digitally thinking,
we use every bit either using 40% or 90% of the volum. Bechause the
zeroes 0`s are also bits.

Staying on topic is of course best for the poor person who maybe ask for

I have had off topic post a couple of times :) If somebody correct me i
willl not be hurt :) Computer – audio – hifi is interesting and it is
fun to discuss. It is easy sometimes to be carried away and forget the
topic. Off topic posts is just to ignore and ask a relevant question

Re: [SlimDevices: Audiophiles] Empirical Audio Pace-Car Reclocker

2007-08-31 Thread eiret

It is an great respect for Empirical Audio AND for Benchmark Audio
products. I am just an amateur reading reviews and forums and deciding
what is the best setup for me $$. And posting some thoughts and
questions. Both Benchmark Audio and Empirical Audio are good products,
no dought.

I have 2 computers – 1 SB3 – QUAD 12L ACTIVE
http://www.quad-hifi.co.uk/model.php?sector_id=2&range_id=5&model_id=23

Whith Benchmark DAC1 USB i can connect 2 computers and Squeezebox to
the DAC and also have an headphone amp. And the QUADS have XLR inputs.
Benchmark DAC1 USB has special XLR outputs for studiomonitors. As far
as i know the Benchmark don’t use as much CPU and RAM as an software
upsampler Empirical use do(that said at the risk of misquote again). I
will go for Benchmark DAC1 USB later next week.
I am waiting for an spdif to XLR(aes) transformer. Hard to get here in
Norway. No i have to get some things done. Have only had time to rip 2
cd`s he he … while reading reviews and forums about software player.
etc and hardware. Foobar – EAC – Lame mp3 – Flac - SB3 – Benchmark DAC1
USB – QUAD 12L Active is my choise. No i have to work with this tools,
not just read forums and reviews, i have finally made an decision about
software and hardware. Its time to learn to use the tools.

I will post questions in the beginners forum.

"100% jitter immune" is not the same as "100% jitter free".

Sorry it is a MISQUOTE. It is nearly 100% jitter free. That IS a
difference. 

Taken from Benchmarks website.

The Benchmark UltraLock system is nearly 100% jitter immune. The D/A
conversion clock is totally isolated from the input digital audio clock
in a topology that outperforms two-stage PLL designs. In fact, no
jitter-induced artifacts can be detected using an Audio Precision
System 2 Cascade test set. 

One man posted in a tread in another forum. He worked in a studio. Dont
remember where or when. His statement of claim was that jitter dos not
exsist. It is something the pro audio hardware industry has invented to
earn more money on hardware sales.

Re: [SlimDevices: Audiophiles] Empirical Audio Pace-Car Reclocker

2007-08-29 Thread eiret

Interesting test/article.
This Steven Nudget(Emperica Audio) coming from Intel and silicon valley
has knowledge about dac`s, circuits, opamps. No doubt.

Same with the engineers at BenchmarkMedia.

They are on an collision course, maybe. They both want to engineer good
dac`s, but Steven Nudget goes for uppsampling on the computer and
Benchmark engineers goes for uppsampling natively in their dac`s.
Benchmark DA1 USB does completely seperate the data from the clock. No
audible jitter. The digital part of the convert uppsamples to 110khz
and the analog part downsamples to an audible range. Dont know the
samplerate ?
http://db.audioasylum.com/cgi/m.mpl?forum=digital&n=94575

Benchmark recommends to remove all dsp plugins and other plugins from
foobar to eliminate loss in word lengt- bith depth - sample rate. If
our goal is to hear as exact as we can, what the producer engineers
produced on the cd. Bitperfect. 
They clame that the Benchmark DAC1 USB dont have any jitter at all and
the audio will sound the same coming from harddrive, cd player, dvd
player connected to Benchmark DAC1 USB. So why use software to
uppsample in the computer. Using CPU and RAM resources when the
Benchmark do it so well.
http://extra.benchmarkmedia.com/wiki/index.php/Main_Page

Or maybe the Empirical Audios software uppsampling on the computer is
the best way ? 

The best way to decide would be to borrow products from
Slim Devides, Benchmark, Empirical and have our own test in oour own
audio set up. But that`s not easy to succed.
Therefore it is fun and useful to read reviews and forums.

Okay, that sounds interesting. Maybe this the way of getting the best
possible sound from albums in the future. Strange to think about how
audio bits can travel all over the world on the internet without
decrease in sound quality. If you have a good enoug audio set up at
home.

Re: [SlimDevices: Audiophiles] Windows VOLUME

2007-08-13 Thread eiret

I was in properties sound/sound devices. Everything related to volume is
set to max/best. I must say that i use softsqueeze when using
Softsqueeze when using Squeezebox. Havent tried to implement Winamp or
other in Slimserver yet. Using Winamp or Windows mediaplayer throug M -
audio revolution 7.1 soundcard when whatcing movies and just tried some
cd`s. Windows sound properties have found the soundcard. It is just
that the sound is mouch higher in Winamp in the other softwareplayers.
Looks like hte soundcard and Winamp are getting more gain than souncard
and Windows mediaplayer.

I dont know much about soundcodecs but here are they i have in
controlpanel - properties sounddiveces - hardware - soundcodecs -
properties - properties again.If you click on one codec and then
properties, you get the choise to make the marked codec priority from 1
- 12. Which of them shoud the 1. priority.

[SlimDevices: Audiophiles] Windows VOLUME

2007-08-13 Thread eiret

Another strange thing. Not using Squeezebox Slimserver. Windows
Meiaplayer lost volumepowwer. Like in decrease  of how high i can turn
the volume knob ---(in windows mediaplayer). Active monitors volume
knob are turned to 50%. To get high volume, like that neighbours dont
like, not really that high, but high enough to dance. I have to turn
the volume knob in Windows Mediaplayer to 100%. Compare to before, when
i hade to just turn the volume knob to about 40%. An decrease in 60%.
SAME SETTINGS, when using WINAMP, i have to turn the volumeknob 20% to
reach really loud volume. Squeezebox - Softsqueeze Slimserver player
are a little to slow getting volume higts too, compare to WINAMP. Whit
actve monitors turned to 50% i hav to turn volum knob in softsqueeze to
90%. I dont think this is normal compared to Winamp whre i have to stop
at 30 - 40%. Looks like Winamp gets allmosst all the volume gain from
windows.

Anybody that have any ideas ow how to fix this, so Squeezebox,
WinsowsMedia player can get the same volume gain as Winamp ?

[SlimDevices: Audiophiles] SqueezeBox + computer + QUAD 12L Active + DAC

2007-05-10 Thread eiret

I have a few questions, but i am not 
an audiophile high -  end user or expert. So the questions maybe appear

stupid. Anyway, i will be wery pleased if you take your time and
answer.

I am considering a purschase of Quad 12L Active studio monitors 
http://www.whats-new-at-totallywired.com/march2007news.html. When they
comes 
to dealer in Norway. I know, they are primary ment for use in music - 
recording not audiophile lissening. I will listen to them connected to
my 
computer first. The setup will be computer - Squeezebox - 12L`s ative -

possibly with an external DAC in the future in this line of setup.
Computer – Squeezebox – 12L`s active.

Where shoud the external DAC be placed ? I think computer - Squeezebox
- 
(here)DAC - 12L`s active. If i`m wrong, make it rihgt for me please.

In this case of set up, will the computer soundcards quatilty and DAC`s
have 
an impact of the sound ? Will the computers soundcard just be a
transporter 
of audio bits. Soundcard is M - audio revolution 7.1 with only mini
jack`s, 
but have digital out SP/DIF (or is it coaxil out ?). 
http://www.m-audio.com/products/en_us/Revolution71-main.html Will a
card 
like M - audiphile 24/192 give better result in a audophile matter ? 
http://www.m-audio.com/products/en_us/Audiophile192-main.html

Is digital out the same as SP/DIF ? If so, when using this SP/DIF 
connection, do i bypass the soundcards DAC`s ? Maybe thats the point,
if my 
goal is to acheive best possible stereo audio with use of extarnal
DAC`s and 
Squeezebox with this equipment? Try to correct me if i`m wrong. How do
i 
connect this gear ?

Then, if SP/DIF bypasses DAC`s, do i have to use analog outs from the 
external DAC`s connected directelly to the 12L`s active ?

Is it DAC`s in amplifiers ? If it is, can i use the DAC`s on the 12L`s

active amplifier instead of an external DAC ? Will an external DAC give
better audio resolution ?

Is it possible to get use of several DAC`s for example 2 - 3 ?

Can you help us providing a guide on how to connect computer - 
Squeezebox - 
extarnal DAC - 12L active`s ? What kind of cables form soundcard - 
Squeezebox - external DAC - 12L active`s. What kind of cable  from what
kind 
of output/input. Do only need a guide on how to connect this gear.
Software 
and drivers i will install quite well, i think.

What kind of mods to Squeezebox 3 do you suggest, with 
this gear ? After maybe just reading spesifications of this gear do you

think it will be better audo resolutions, after modding SB3 and with
use of 
external DAC ? What kind of external DAC do you suggest ? Can I use
MHdt Labs Paradisea + when I don’t have tube amplifier ? Do I have to
go for MHT Labs Constantine ?

First I have to purschase the 12L active and the Squeezebox. Then I
have to save some money 3 – 4 mounts before I purschase a DAC. And some
money saving again so i can afford a mod on the Squeezebox.

I am living alone with my 15 years old son and sometimes some of his
friends 
in the same 25 squaremeter room. So we both need a decent sound since
we 
have to listen to each others music taste either we will or not. But we
like 
the same music pretty often. If the sound is okay we both will have a
nice 
time. Me and my son will be wery pleased for answers to these
questions.

Best regards

Terje and Daniel
