[SlimDevices: Audiophiles] BW Lossless article

2008-12-31 Thread swarduk

This is a nice article on Lossless v Optical Disc by BW:
http://www.bowers-wilkins.co.uk/display.aspx?infid=3534terid=3537

I have seen lots of posts about some quite niche recording companies
offering high quality FLAC files, what does everyone think is the main
reason why the bigger recording companies have not started doing the
same?

It's great to have so many serious audiophiles on this forum using
Squeezebox/FLAC to play music, does that mean that many of us have
stopped investing in CD players altogether, or is the general consensus
that for now Lossless file playing using SBs is mainly for convenience
rather than serious playing?

Would love to hear your views!
Steve.

The world is divided on this point right now. However, things seem to
be moving slowly but inexorably towards HD replay and away from cd
spinners. The initial driver was usability/convenience (free you
music) but now we are entering the area of improved sound quality. As
far as high-end is concerned, we are maybe  2-3 years from the tipping
point IMO. Some big players are preparing to drop their CD spinners...
but the cost of HD solutions is still too high to make this a mass
market proposition. When a single box HD unit is available from (say)
NAD or Arcam at $1,000 or less the tipping point will be upon us.

HD replay is probably where blu-ray was 12 months ago.. ?

Re: [SlimDevices: Audiophiles] Served music sounds better?

2008-12-31 Thread Phil Leigh

bhr1439;377315 Wrote: 
 Hi, I'm the original poster on this thread.  Thanks for the thoughtful
 comments, everyone.
 
 First off, I appreciate Phil Leigh's insights; he pointed out two
 potential mechanisms that could potentially generate an audible
 difference, reminding me that that both paths start with the optical
 disc.  That is
 
 path A: optical disc -- Nakamachi CD player optical pickup subsystem
 -- decoding and error correction (single pass)-- synchronous
 bitstreams -- S/PDIF waveform encoding -- TacT 2.1S processor --
 Mark Levinson 360S DAC
 
 path B: optical disc -- computer CD-ROM drive optical pickup subystem
 -- decoding and error correction (with optical drive retry, if needed)
 -- harddrive -- S/PDIF waveform encoding -- TacT 2.1S processor --
 Mark Levinson 360S DAC
 
 Path B will likely generate the more accurate data, as it can retry
 reading bad data, wheras it's typical for a CD player to press on
 regardless and use tricks such as interpolation to bridge over known
 bad data.  Different data means different audio, and it's reasonable to
 think that more accurate data will correspond to a more appealing aural
 impression. 
 
 As a previous poster suggested, recording and comparing S/PDIF data
 should be able to confirm or reject the hypothesis path B data being a
 more reliable representation of the music. What I would expect to see
 is rock solid repeatability in the S/PDIF stream originating in the
 server, and run-to-run variability in the datastream originating from
 the CD player.  Now, if only I had an S/PDIF recorder...
 
 Another point Phil makes is that path A has potential for a noisier
 S/PDIF signal, due to EMI from the CD player's electromechanical
 components.  Noisier S/PDIF signal can result in increased jitter in
 the recovered data clock, and increased DAC clock jitter is known to
 make for a less pleasing aural experience. 
 
 JezA strongly suggests that I try taking my TacT processor out of the
 path and seeing if that makes a difference.  That's a reasonable
 troubleshooting experiment, and I will try that as opportunity permits.
 I don't expect a difference, though.  That's because I'm using the Tact
 processor in digital-in / digital-out mode and there never is any D/A
 conversion occurring inside the box.  True, there is clock recovery
 happening as part of the conversion from S/PDIF waveform back to
 digital data stream for processing, but I do not expect that jitter is
 affecting the integrity of the bit stream content (i.e., I do not
 expect misclocking of data and changed data words -- this would be
 HIGHLY audible as impulsive pops in the audio when it is converted to
 analog downstream).  Also, the Mark Levinson 360S employs a FIFO buffer
 and locally generated clock that obviates the S/PDIF waveform (generated
 at the output of the TacT) as a source of clock jitter. 
 
 So, no smoking gun yet that confirms or refute my impression, but at
 least there's a plausible (to me) hypothesis on what's going on.  
 
 --Steve

Steve - as a small aside the  high-quality ASRC chips in the TACT are
indeed doing a D-A-D process internally in order to change the sample
rate and bit depth  in realtime to 24-bit/184kHz for the internal DRC
process. You can find in-depth discussions of the mechanics and
implications of these chips elsewhere (Google).

This is basically where the jitter-sensitivity comes in; even though it
seems to be an entirely digital process...it isn't.

Changing the TACT PSU and using adequate 1.5m spdif cables (the length
is important) all help. 



But this is off-topic. The issue I thought we were discussing can be
restated as Do transports sound different - and why could the SB
transport be better than a CD mech?. The TACT is a red herring in
this discussion!.

As Themis says, accuraterip - a program that computes a checksum from
the file you ripped and compares it to the results that thousands of

zero.

By the way, what DCtoDaylight said is also relevant - not every disc
rips perfectly, even when new.  But it's only on at most 1 in 20 new
discs that I have a problem - and even then, it tends to be localized
to one or two specific locations on a few tracks.

Correct, but data CD's have another layer of error detection, which

[SlimDevices: Audiophiles] Stone Harley - new comedy team?

2008-12-31 Thread Pale Blue Ego

Or just incompetent hacks?  Tasked with covering the expanding
audiophile music server sector, they each reveal an alarming
cluelessness.  These old dogs can't seem to learn a new trick, except
for the one being pulled on the readers of their columns.

Apple fanboy Steven Stone can't get his mind around the idea that
RIPPING a CD is not the same as BURNING a CD: The Music Vault allows
you to burn CDs directly into a music library.  No, that wasn't a
typo, because he repeats the gaffe a few sentences later: ...the Music
Vault offers a clever way to burn, store, and access your entire digital
music library.  He seems oblivious to the fact that such devices have
been around for at least 9 years and there's nothing especially
clever about ripping a CD.  Nor does he pick up on the idea that this
$1500 Music Vault is nothing but a $500 PC in a different case.

(Note to Steven: the term burn refers to the use of a (insert Dr Evil
voice) la-ser.  A small la-ser burns tiny pits into the substrate
layer of a blank disc.  Hard drives are magnetic recording devices and
no burning is involved in storage or retrieval.)

Stone reveals his Apple bias in another piece about Channel D Software:
The limitations to the software are that it only works on a Mac
(grin)...  Why does he think software unusable on 90% of computer
systems is something to grin about?  Idiot.

Robert Harley then shows that mastery of 2nd grade math continues to
elude him.  In a discussion of the PS Audio Perfect Wave transport he
says, The transport has 64GB of RAM on-board, enough to store 4
minutes of music.  Very close, Robert.  You only missed by a factor of
1000.  The correct number was 64MB.  The $2000 Perfect Wave seems to be
little more than an ordinary DVD-ROM drive, plus a small LCD touchscreen
interface.  It has no storage of its own, requiring a NAS for local
storage.  You will also need to connect the Perfect Wave to the
internet if you want your files to include any meta-data.  Still, PS
Audio will offer a ripping service in which you can mail them your CD
collection and they will mail you back a hard drive full of ripped
files...essentially making the Perfect Wave transport obsolete.  Nice.

I'm still waiting for one of these nifty new music servers to offer
something that a $300 PC can't do.  I guess it'll be a long wait.  Slim
Devices' philosophy of separating the audio playback hardware from the
cheap commodity PC hardware continues to be the more elegant,
practical, and economical solution.  Meanwhile, the audio industry
plods into the computer age, continually repackaging variations on the
1999 ARQ1 while Famous Audio Journalists steadfastly fail to notice the
scam.

2. Flac's streamed as wav sounds better then native streaming.

3. Squeezecenter 7.3.1 sounds wierd compaired with 7.2.1.

4. SPDIF sound better then Toslink.

Help me, please, I really don't believe in this kind of shit but to my
ears it makes a huge difference.

2008-12-31 Thread dlhamby

What did you do for controls, Stefan? Unless you controlled for level
and experienced all of this double blind, it is likely that you are
experiencing placebo effect on some of these, particularly those
changes where the squeezebox or transporter is doing the final retiming
and conversion. 

Bits are bits. If you keep the Squeezebox fed and are feeding it the
same format, it should not care where the bits came from. After all,
the BBC makes it all the way to you from the UK with a second of
latency and maybe 0.1 second of latency jitter. Squeezecenter can
buffer it and spool it to Squeezebox which has yet another jitter
buffer. Squeezebox reconstructs and retimes the sample stream. All the
jitter in the world (well until the buffer runs dry :) never reaches
your ear, just that introduced by the Squeezebox itself.

With this understanding, moving your music library from an internal
disk to a NAS should have no effect on the sound coming out of the
Squeezebox or Transporter. Some of the other changes such as SPDIF to
TOSLink may. SPDIF is notorious for its jitter. But again, we are
filling a buffer and regenerating the timing. I can see a difference
resulting if the jitter is so bad that a bit is lost every now and
again. This would cause actual errors or dropouts in the sample
stream.

The way around this is to use forward error correction by using
Hamming coding or one of the newer forward error correcting techniques
like those used in disk drives. Even if a bit is lost every now and
again, the bit-stream can be recovered. I don't really know the details
of SPDIF, only that it dates back to the beginnings of digital audio
production equipment and is obsolescent.

Bit jitter should not have a big effect on playback as long as all of
the bits can be recovered correctly off the SPDIF waveform. The bit
stream can always be buffered and retimed. The last device to buffer
and retime the bit stream determines the pitch accuracy and sample
jitter. What happens along the way is not seen unless the pipeline goes
dry.

Sample jitter is interesting. From my introduction to digital signal
processing in college, jitter (non-uniform sampling in geek speak)
introduces noise in the reconstructed audio. A classmate did his
masters thesis on the subject deriving the effects of nonuniform
sampling. My recollection is that he concluded that the noise was
Gaussian for the sample jitter distribution that he examined. This
would show up as a raised noise floor in the playback. It would be hard
to notice a tiny amount of jitter on most program material.

FLAC and Apple Lossless do give you back the original bits. Folks have
verified this. I ripped an CD to one of each, loaded into Audacity, and
played the tracks. I couldn't hear a difference. There can be a
difference if you are not normalizing the levels or you are using
different play back level management schemes. These can cause the
levels to differ enough to fool you.

I demonstrated placebo effect to myself some years ago. I bought some
Nordost cables (the modest ones) to replace some way too long monster
cable that came with my trusty DQ-10's in the early days of Monster.
The difference was dramatic after the change. The next day, things were
back to normal. I expected a change and, by Jove, I heard one. I'm not
so quick to form opinions about a change after that experience.

Interestingly, the woofer surrounds failed and I never noticed. I had a
local pro audio shop renew the surrounds and the DQ-10s are still going
strong at 30 years young. It has been 13 years so I've forgotten what
prompted me to take the front panels off to look.

My rig: SB3, Conrad Johnson PV-1, Gas Ampzilla, Dhalquist DQ-10s. 
Computer audio: Presonus 1394 and Monsoon Audio planar desktop
speakers.

When it comes to reviewing and writing about music servers Stereophile
is light years ahead of The Absolute Sound. At least the writers at
Stereophile know the difference between ripping and burning and some of
them even know what meta-data is!

But as sad as TAS's coverage on music servers may be, it is still way
better than the trash that comes out of your average computer
publication since at least TAS is concerned with sound quality.
However, TAS completely misses the boat when it comes to price versus
performance versus sound quality issues which, as all of us Slim
Devices fan boys know, is where the SqueezeBox clearly leads the
field.

No, you miss the point, TAS thinks more expensive sounds better.
They love cables that cost five figures and speakers that cost six.

What I don't understand is why they don't have expensive cigars and
single malt scotch to go with their favored products.

Re: [SlimDevices: Audiophiles] BW Lossless article

2008-12-31 Thread kphinney

Let me preface this by saying that I enjoy listening to music.  In any
forum except one dedicated to Audiphilia, that may seem to be a simple
but telling statement.  Here, it may sound as flat as one of those
new knock-off Mullard tubes pushing a ripped speaker.

The point the article is attempting to make (and I have no disagreement
with their facts) is that data streams can, or will be able to, deliver
more bits than a CD and more bits = more resolution.  More resolution =
better hi-fi.

I'm fine with this too, but we've lived thru it before and I play with
it all of the time: SACD vs. vinyl.  About 30% of all topics on this
forum say something akin to you need to listen and find what works
best for you... or the like.  120% more data flowing form the
ether-regions of the world thru my system and into my ears may _not_
equate to even a 1% increase in subjective quality reaching my
ear/brain.

A prime example may come from my own switch (or downgrade as some may
say) from BW 704's with a 300w Rotel amp to my little Omega Grande
full-range fostex speakers and a 25/25 watt tube amp.  Nothing against
BW - they gave me the foot up into hi-fi and away from the low end
audio equipment I grew up with.

Where I believe the BW philosophy will have a big hold is with the
sub-audiophile crowd; imagine all of the masses having access to
uncompressed 24/96 or greater.  

To quote the article:
  But the format#8217;s #8216;lo-fi#8217; image is somewhat ironic
 because digital music actually holds the promise of the highest quality
 of all, by making it possible to reproduce in the home environment a
 level of quality that is currently restricted to the very best
 recording studios.
 Music compression formats such as MP3 were first used simply because
 the maximum speed offered by dial-up modems in the early 1990#8217;s
 made downloading CD-quality digital music impractical. Fifteen years
 later, in spite of the widespread availability of hi-speed broadband
 connections, most digital music is still offered with compression,
 simply because the average user favours convenience over absolute
 quality. But this does not mean that digital music has to be supplied
 in a compressed format.

Good job BW.  I really do hope all audio manufactures - hardware,
software, and recording artists alike -- pick up on this sooner rather
than later.

Oh, and for those who still don't trust downloaded music and want a
copy on vinyl or CD... well, I gave up my fax machine and filing
cabinet in leu of PDF's and a backup hard drive.  My life is easier and
much cleaner and I can find what I'm looking for.

As of 7.3 the server will transcode files which have too high a bitrate
down to whatever the player can handle. As of 7.3.1 (IIRC) it will do

This topic comes up quite a bit, I've noticed. And we see higher

Music. 

Any idea when there will be a Duet2 that can at least pass through up

After I started using my Sb2 I haven't used my cd transport anymore.
It's just way too convenient, and the sound quality is the same. And by
now my ears are bad enough that I can't hear the difference between the
SB2 into a decent DAC and a Wadia transport anyway. Good for me I guess
:-)
Of course I still buy CDs, but all I do with them is rip and store in
the closet. So they are sort of my backup. If stores like Linn Music
had more music I like I'd be buying there a lot more...
Having said that, I do think there's still a problem for this to become
mainstream. I recently got a Duet for my bedroom, but my wife still
prefers just turning on the radio to listen to PBS, even though it's in
the Favorites on the Duet. But it's still too techie I guess. And then
sometimes it doesn't quite work, or it takes a while to connect to
Squeezenetwork, or things like that. It's still not as easy as turning
on that radio. I can deal with that, because I just think it's cool. But
most people can't... Yet...
