Re: [SlimDevices: Audiophiles] HD Music Downloads from iTrax

2007-04-30 Thread agentsmith

I own a few of your DVD-As and has read from one of the magazines from
an article you wrote about high definition audio that you were
planning for online downloads.  

Being a Slim user this is really good news and I am not suprised that
you are also one of us.

I was excited about download offering from HDTT and have bought a few
of their downloads.  But HDTT focuses on historical recordings so AIX
with their well recorded material would be even better.

One question I have is that SB3's digital output maxes out at 48Khz/24
Bit Stereo.  Will you be offering that in addition to 96/24 for the
transporter?

Another quesiton is: What happened to the Jennifer Warnes recording
that I have waited for years?

[SlimDevices: Audiophiles] Potential benefits of converting to 24 bit

2007-04-30 Thread adamslim

In a thread on the ripping forum recently, mswlogo has sussed out how to
'up-bit-depth' his flacs from 16 to 24 bits.  Filesize is similar, as it
just compresses out, so no downside.  The file is padded out with
zeroes, so there is no change 

Potential upsides he gives are reduced jitter and (if applicable)
better DRC from higher bit depth of processing.  The latter I don't
care about, but the former is interesting.

Comments?  I would have thought that higher bit depth would change the
data timing, but would it always improve it?  Analysis from techies
welcome!

I don't see how simply having more bits (with no information in them)
makes it any more likely that any of them will arrive at the right
time...I would have thought that it's even harder to control jitter at
higher bit rates, since everything is happen faster if you see what I

Re: [SlimDevices: Audiophiles] Potential benefits of converting to 24 bit

2007-04-30 Thread AndyC_772

Jitter will be exactly the same. The SPDIF spec transmits 32 bits of
data per sample anyway; up to 24 of these are available for the sample
word (with the bottom bits explicitly set to zero if unused!), and the
rest are overheads such as sync pulses, checksums and other stuff.
Apart from possibly changing a flag bit or two in the general-purpose
data area, there is ABSOLUTELY NO DIFFERENCE between transmitting 16
bit samples, and 24 bit samples where the bottom bits are all zero.

Since there is no difference at all in the bit stream, there will be no
difference in downstream processing either. If a DAC is capable of
oversampling / filtering to 24-bit accuracy, it'll be doing that anyway
even with a 16 bit input, probably without even knowing the difference.

Re: [SlimDevices: Audiophiles] Potential benefits of converting to 24 bit

2007-04-30 Thread mswlogo

If your going to upsample as well doing it in larger word length is more
accurate (some would say a better guessitmate). Upsampling doesn't make
a lot of sense with Slimdevices because SB3 only does 48khz and
Transporter doesn't do 88.2Khz. BUt my library is for other devices
beside the Slimdevices.

I don't know why but in this stereophile review of the transporter 16
vs 24 changed the jitter measurement.

http://www.stereophile.com/mediaservers/207slim/index4.html

Snippet:

I tested the Transporter's rejection of word-clock jitter using the
Miller Jitter Analyzer, which examines a narrowband, FFT-derived
spectrum of the analog output of the device under test (DUT) for pairs
of sidebands around a high-level tone at one quarter the sample rate,
while the LSB is toggled on and off at 1/128 the sample rate. (Both
signals are exact integer fractions of the sample rate, meaning that
any spuriae that appear in the spectrum are due to the behavior of the
DUT, not to quantizing distortion.) Fed 24-bit data via the WiFi
network, the Transporter developed just 235 picoseconds peak–peak of
jitter with no data-related components (not shown). Decreasing the word
length to 16 bits gave the spectrum shown in fig.10. Here the jitter
level has increased slightly, to 268ps p–p; though there are
data-related sidebands (red numeric markers) at the test signal's
residual level. The primary jitter components lie at ±15.6Hz (purple
1) and ±1435Hz (purple 10), but this is still excellent
performance.

Let me recap what user creativepart is stating. Ran SlimServer on a Mac
Mini that connected wirelessly to a SB3. Then tried using an external
DAC with the SB3 using the optical output of the SB3. Then connected
the Mac Mini directly to DAC using an optical connection.

States how much better Mac Mini, running iTunes, is when connected
directly to DAC. Acts petulant when claims are questioned.

I think creativepart is disingenuous because the optical cable between
a Mac Mini and the DAC cannot be the same as what was used for the SB3
to DAC connection. The Mac Mini uses a dual purpose audio output that
will work with an electrical connector as well as an optical connector
and this physical connector is not the same as those on a SB3 or the
vast majority of audio/video components.

My conclusion is that creativepart had some reason to make claims that
weren't factual so I am choosing to ignore what was said.

But didn't you just say 16 vs 24 wouldn't make any difference in the
actual jitter of the 32bit word. Why would it matter which bits are
being used in the test?

So your saying each bit has it's own jitter measurement?

Or if he toggled Bit 8 of the 24bit word he'd get the same measurement
as bit 0 of 16bit?

That makes no sense to me.

I must admit, I don't know for sure why the test results are different
- but I suspect it's much more to do with flaws in the test itself than
the behaviour of the Transporter.

For example, the AK4396 DAC is a 128x oversampling delta-sigma device,
so there will always be data-dependent noise at frequencies outside the
audio band. More than likely there is an analogue filter between the DAC
and the output socket to attenuate this noise.

Now suppose that, in order to allow excellent flatness up t0 22kHz,
this filter has a cutoff around 100kHz. The test equipment is now
trying to pick out jitter in the order of 100ps (which is the period of
a clock running at 10GHz) in a signal which has been filtered to remove
everything above 100kHz.

Is that a sensible thing to try and do with any degree of accuracy? Or
is the measurement likely to be influenced by the audio signal? I
strongly suspect the latter.

I'd bet that if the jitter measurement were made at the MCLK pin of the
AK4396 - the correct place to measure it - that it would be completely
independent of the data.

Ok, thanks Andy, I think we are closer to the same page now.

I figured it wouldn't hurt to play with.

I'm also not sure how my processor handles 16 vs 24 bit and may do some
odd things to be backward compatible with different devices. So I
figured it wouldn't hurt to play with. The first thing my processor
does is shift the data down to make headroom for some processing and
calibration. I don't know if it does that in 16bit on 16bit data or
converts first. It is capabable of outputing 16bit data to older active
speakers and that data is just lost. With newer active speakers I can't
tell what it does because SPDIF data is encrypted.

So far I hear no difference. But I need to try it on a wider range of
music.

Also just a thought wouldn't replay gain (done digitally) or any
normalization now have lot headroom in 24bit?

2007-04-30 Thread AndyC_772

What I was getting at, is that your DAC, or your processor, or whatever
else is connected over SPDIF, simply won't know whether it's getting 16
bit or 24 bit data. The SPDIF frame includes 24 bit positions for use
with audio data, and a source that only has 16 bits available simply
pads the missing bits with zeros.

So, there cannot be any difference in how your processor handles the
data. That's why you can't hear any difference.

SPDIF (at least, the 2 channel uncompressed version we're using) isn't
encrypted, BTW - just encoded to ensure plenty of edges for clock
recovery. The AES/EBU spec is freely available and explains exactly how
to decode it - you could do it with a storage scope and a pencil  paper
if you wanted.

Stereophile's jitter measurement in this case is just nonsense. They
are using the Miller jitter analyzer, which implements the test
described in Julian Dunn's Jitter and Digital Audio Performance
Measurements. The test measures data induced jitter in -a manchester
clock recovery circuit-, i.e. an s/pdif receiver. It can not (and is
not intended to) measure anything else! Since they used Transporter's
internal clock, not its s/pdif receiver, the test is simply

Well initially, the source (one of the above) directly into a power

Hence, this thread, to get an idea as to what sort of £ ratio a pre amp
should involve, so as not to degrade the HQ source.

By the sounds of Cliveb and Patrick's experience, as well as
Robin#8217;s cd direct option [thanks for the posts :)], I should
revert back to my original thoughts on set up, and save spending out :)
on a pre.  

I#8217;m getting a strong vibe from the rest of you that speakers may
just, play an important role :)   pre money - speakers then.


Adam, I was thinking of:
Source, as above, feeding, 
either a couple of Exons, a KST-150, or maybe a Bryston, to
my existing speakers(for the time being) or possibly some Totem's down
the line.


But, in avoiding a pre, I'm in need of an idea or two, to get the other
sources into the power amp.  Not so bad, if I like the TP or a dac, but
if I prefer Patricks SB+  :o

So then Patrick, if I end up preferring the sound from your SB+ are
there any options to get, either an additional analogue or digital
signal, through your unit?

Thank you everyone for your helpful posts so far :)

I think I follow what you're trying to say there, but it does not
apply. The volume function is always 24 bits wide. It doesn't know or
care whether the lower 8 bits are used, and all 24 bits of output are
meaningful regardless of the input word length.

 Are you saying that even digital volume done on the SPDIF output (i.e.
 replay gain) of a SB3 is effectively done on a 24bit word?

That's exactly right, if you drop the word effectively. There is no
effectively. It's precisely the same operation, not merely the same
result. The _input signal_ in either case is precisely the same.

 The volume function is always 24 bits wide. It doesn't know or care
 whether the lower 8 bits are used, and all 24 bits of output are
 meaningful regardless of the input word length.
 
 
 
 That's exactly right, if you drop the word effectively. There is no
 effectively. It's precisely the same operation, not merely the same
 result. The _input signal_ in either case is precisely the same.

Ok, I understand the SPDIF part.

But if I have a 16bit wav file, and applied a normalization (not replay
gain, static normalization of the data). which may reduce it's volume
and it wrote out a new 16bit file, data is lost due to a Volume
change. So if I converted that file to 24bit first then did
normalization it would unlikely lose any data. Correct?

On a similar topic, do plugins like the room correction also work in
24bit (when fed 16bit wave file)?

yes any static normalisation is a bad idea, regardless of how many bits
you have to play with. The engineers did their best to master your
bits...do not mess with them - you will not make them better - only
different :0)

 I went to a cool and famous hifi shop once (Thomas Heinitz, Notting
 Hill), and the mad old chap running it (Heinitz himself who has since
 sold out) explained to me how almost all your cash should be spent on
 speakers. he had this £15k valve amp someone had ordered, and he was
 playing with it before they picked it up, and doing demos for select
 customers.. The difference between the 15k amp and a decent normal one
 was questionable... but the difference between various speakers was
 huge. He was a great chap if you were lucky enough to get to know him
 (I met him through my father who was a favorite customer). Although he
 had a bit of equipment in the shop he only really sold two systems, one
 based on small Rogers speakers with a subwoofer and the other on quad
 electrostatics.

Yeah, this is just obviously true, at least if your goal is high
fidelity (meaning accurate reproduction of recorded music).  The
differences between amps or sources operating normally is measurable
but extremely small and usually inaudible, while the differences
between speakers is (relatively) huge and easily audible.  Furthermore
some speakers perform much, much better than others, with good
performance defined as, for example, a close to flat frequency/phase
response.  

So you have the potential to get much more for your money when you
invest it in speakers, or perhaps room treatments and equalization/room
correction, than you do from sources or amps/pre-amps.

I can only guess what you mean by unlikely or losing any data, but
the only reason you would get more precision in the latter case is
because the volume function you are describing happens to be designed
to output 16-bits when given a 16-bit input. A volume function could
just as easily generate 24 bits of output, or 137 bits for that matter,
from a 16 bit input. There is nothing about padding the the input signal
to a longer word which causes a more accurate output. Obviously if you
truncate your result to 16 bits, it is less precise than if you have
not truncated it.

I think that's a little harsh. I re-read his postings and didn't feel

I have a laptop connected to my DAC as well as a SB2 (with modded PSU)
and there isn't a big difference in sound between the two. I wouldn't
expect one unless the jitter performance of the laptop was really bad
compared to the SB2.

For those of us with some iTunes store purchases, it's a damn fine
alternative, and even on lossless tracks that I have ripped myself, it
can sound better since SlimServer seems to induce volume clipping when
compared to iTunes playback of the same tracks.

Re: System Balancing � - your thoughts please

2007-04-30 Thread Squirrel

Heard a Transporter at the Sound  Vision show back in February...

Awesome.

Sounded better than a NAIM CD player on the same system.

Problem is, I can't justify spending £1,200 on one.

My current setup, sources first:

Arcam DV-79 CD/DVD-Audio player
Rega Planar 3 turntable, Ortofon 510 cart, Pro-Ject Phono Box II
Technics RS-BX606 cassette deck
Sony RCD-W100 CD recorder
Sony MDS-JB980 minidisc deck
Turtle Beach Audiotron
Pinnacle ShowCenter

Arcam AVR-250 AV receiver

Mordaunt-Short Avant 908 front, 905C centre, 2x 903S surrounds
BW ASW-1000 subwoofer

Chord Cobra 3 interconnects between DVD and amp
Cambridge Atlantic interconnects between everything else and amp
Chord Rumour 4 speaker cable for front and centre
Gale XL-105 for rears (buried into plaster)

At present I use the Audiotron as a network media source as it fits
nicely in the kit rack. Granted, a Transporter would be better for this
(FLAC support anyone?) but as mentioned above I can't justify spending
this kind of money. What I'd really love is a standard SB3 mounted in a
hi-fi component size case with front panel buttons, but without the
fancy DACs of the Transporter. Probably be happy without the dual
displays as well... just a SB that will sit in the kit rack and look
right - and be operable without the remote.

I've had an SB3 hooked up to an offboard DAC (Arcam Black Box 50) and
the results have been superb.

Re: [SlimDevices: Audiophiles] Quality streaming music...

I am struggling a bit with the radio here. Sorry, I need some help and
easy explanation.
I really like the Shoutcast HAPPYDAY contemporary radio station, but I
have lots of annoying dropouts, re-buffering, in the stream from time
to time.
I would love to get links to URL´s on similar, quality sound
stations, these I can then glue into Tune in URL, or find at
SqueezeNetwork, or do both
I signed up at Radioio but the stations there dont suit my taste, sorry

Certainly many people share your views, but that just hasn't been my

weak points, which jump out at me more and more on certain tracks.  On
the other hand I appreciate the qualities of speakers I like again and

sources, even over lots of time.  

I used to think that was just me, and it's still a possibility - but
I've learned that just about everyone else also has great difficulty
distinguishing digital sources and amps, at least when blind.  Granted,
those are short tests, and you can always find something to criticize in
them - but no one has any difficulty at all telling speakers apart.  

I rest my case.

O,  I tend to agree with you but once you have a highly resolving
speakers the other components start to make a bigger difference.
I do hear some differences between amps and digital sources in informal
blind lstening (which might not satisfy your rigorous criteria for a
blind test :-)  )

I do think one may have to spend the most on speakers to get the best
results. It seems amps and DACs get to SOTA at a much lower price point
than speakers.

I did blind  test Transporter V SB and the TP was significantly better.
I also blind tested the XLR V RCA outs of the TP into my balanced amp
and the XLR was much better than the RCA.  We did level matching and my
preamp switched silently and seamlessly between RCA and XLR.

That difference was so large that all 3 people listening prefered
balanced every time.
I only refer to this to make the point that once the speakers are
optimized , upstream components can become more important.
