gdg,
you really are out of line.
The posters you are so uncivilly responding to are experienced
listeners who have high quality systems.
Pat, I believe, is professionally involved in the recording industry
and is very knowledgeable about sound reproduction (far more, it would
appear) than you.
A couple of observations:
1) high resolution audio in the domestic replay chain appears to be a
dead duck. DVD-A and SACD have both failed to grab the publics
attention or dollars. I see no reason why this will change in the
future. Clearly domestic audio replay technology has reached the good

I am merely saying that there are many reasons why showing that
wav-flac-wav on Windows is -not- sufficient to prove (100%) anything
about the outcome on the SB3. It does increase the probability that the
SB3 is also doing the -expected- thing.

If this doesn't bother you, or you have an external DAC, great.
I like to see a circuit perform as well as it can be made to; for me
the problem is that this noise limits the s/n ratio of the whole
system, at it's worst it is 27dB above the thermal noise floor.
The fact that it only affects one
Very good - well done.
So basically you've physically inserted a grounded screen between the
VFD and the main circuit board...and the noise is gone or greatly
reduced. I agree that SD/Logitech should improve the screening of the
VFD in future hardware.
Hopefully they will notice this - they may

As for bandwidth I believe HDMI is a necessity in order to accommodate
both video and audio data, not something implemented because coax can't
handle the audio side of it. The first players that are hitting the
market all have the usual coax digital outputs as well as HDMI
I agree that FLAC compresses to 50% of WAV, is easy to encode/decode and
has good tagging facilities like other lossless formats.
On top of that, it is non-proprietary (http://flac.sourceforge.net/),
has support on all major OS platforms and is supported by many devices
On top of that, it is non-proprietary
And that's what swings it for me. We've seen with the iPhone, Touch and
Classic that Apple is now getting 'corporate' with all manner of DRM,
digital signatures and embedded chips to control the use of their
products. I wouldn't used ALAC and risk the

No one said that. The question is how to improve it, and personally I
don't think increasing the sampling rate or the bit depth is going to
do that in any significant way (although there's also no reason NOT to
do

Sadly, I agree. The home theater folks have never cared about fidelity.
Effects subs are often unusable for music.

Ignoring the whole DBT debate for a second, I've found that both

test them easily in my system using my remote). However, when faced

When ABing wma lossless and flac, I seem to remember flac being ever so

The next version of the SB should be a box with no display and a remote
control with a big display. Of course, the big display will be a power
hog, so the remote will need to sit in a nice display stand/charging
dock.
You could do this yourself now by modifying the heck out of the SB -

Hugh, I've been doing quite a bit of measuring, using a number of
different tools. Recently I've been frustrated with the apparent lack
of consistency between TrueRTA and REQW, which I use to look at the
average of the two impulse response channels which I get out of the
measured impulse response

It's trivial to verify that the SB3 decodes FLAC perfectly and it's been
done many times (both by SD and others).
I'd be interested in reading about the methodology.

Why?
Read this carefully:
If the FLAC decoder algorithm in the SB was anything less than 100%
perfect then what would come out would be total garbage.

Yes, the headphone out leaves a bit to be desired. I have a set of

like the way they sound and feel on my head.
So, I broke down and ordered a headphone

When I stream Flac the current value changes in range 0.930-940 A
But when I stream WAV it changes in range 0.925-0.926A no more.

Were these measured with the microphone in the exact same position?
Even with a very small offset from the original measurement position,
you'll notice comb-filtering effects at high frequencies. You can hear
this really clearly if you move your head a few inches while playing
mono pink noise -

Mic was in the exact same spot the whole time.

To measure the in-room overall frequency response with both channels
(rather than a single speaker), you're best to use uncorrelated
Latest ImpulsePrep also adds some subsonic filtering. So if you re-run
against your sweep measurements, you should be able to see better
long-reverb graphs.
