Sean - yes I can hear it.
Please have a look at the numerical examples I produced on the other
thread and in the bug report - the rounding is affecting the 16th bit
and therefore it's 'effectively' at 90/96dB.
The best analogy I can think of, is that you only get 96dB s/n with a
16-bit ADC, if

With all the fancy test gear you have there, can you measure the SNR
with a digital test tone (before and after). I reckon you will find
it's 6dB+ worse with the rounding.

When, exactly, will the patch be incorporated into the nightly? As I
recall, manually inserting the patch is difficult on a WinXP machine,
so I'm still waiting for the native fix.

Sorry Pat, I added this correction later!
Whoops - I meant dither. I have jitter on the brain.

Quick question: does this issue affect the bass/treble control values as
well? I assume mid-level on these will cause no modification of the PCM
data, whereas non-middle settings will. Or is it done in the analog
domain (and analog outputs only)?

I think there are treatments for that. The
modern drugs are very effective.
I am very skeptical about jitter. Folks have been
talking about it
Hi All,
I've just started using a SB3 - and almost everything is working
great. However, I have some DTS/5.1/Wav files that play great when I
put them on a CD (my Yamaha receiver autodetects DTS) - however, when I
use SB3 to play them back I get static. SlimDevices support suggested
turning the

At least one of the modders is removing this clock as part of his
package, presumably to eliminate any jitter associated with it.
My question: if you take this clock out, what kind of files, what bit
rate, etc. are you then NOT able listen to on the SB?

I also am skeptical about how my Benchmark DAC-1's
marketing copy talks about it being completely
totally and unanimously immune to jitter.
Having dismantled a DAC-1 I can tell you it is a perfectly vanilla
implementation of ASRC using a standard ADI chip, and it does perform
