That would probably be because your FLAC files are lossless -
hello sean
thanks for helping, it turned out that my DAC was not working properly.
I repaired it and it works like a charm with the SB2! first listening
tests indicate that in comparison with the SB2 my own DAC reproduces
music a bit warmer and "opens the stage" somehow - yet the differences
are
I would be astonished if any 16-bit DAC has a problem with the other 8
bits being populated. BTW here's a good explanation of s/pdif - better
reading than the IEC spec.

hi sean
thanks for clarifying - I wrote to the author of the DAC design and
will have to wait for his answer for finding out what really happens
there.
so to summarize SB2 sends the following format (certainly a bit more
complex in real life):
MSB 0x00 - 0x0F 16 bit data
LSB 0x10 - 0x17 8 bit a
To clarify: there is no difference in the data format for 16-bit versus
24-bit over s/pdif.
If you play 16 bit with volume set to 100%, you will get the same 16
bits at the output (the 8 least significant bits will be zero).
If you have volume set to some intermediate level then the additional

How are you determining this?

I just got my SB2 two days ago and tried today connecting it to my DIY
DAC (based on the DA1543N DAC, http://www.dddac.de), which works
wonderfully with the digital coax output of my Creek CD play

I assume then that the 16 bit DAC uses the 16 most significant bits of
the 24 bits transferred by S/PDIF.
How does digital volume adjustment work in this scenario?

The additional resolution is just ignored by the DAC - it works like a
16-bit interface.

Interesting. So what happens when I'm outputting it to a 16-bit NOS
DAC?

Here's the one that compared analog and digital operation - this is the
DEQX's predecessor - the 8024 - it was double the price then, and had
nowhere near the digital advances of today, yet he rates it as "value
for money" of 200% ! It's one of the better reviews because he really
concentrates on
Thanks for the info everyone. Looks like I can be sure that no
resolution is being lost relative to the original when I equalize it.
(My calculator says for a 24 bit signal, I've got 48dB of headroom
before I lose resolution). I agree with quadguy, there is such a
noticable improvement in bass

Agreed, it doesn't attempt to handle phase relationships as would an
expensive Tact unit for example. But I only EQ bass and the effects on
phase from say 250Hz down are far less evident than if one were EQ-ing
the critical midrange region. I bought it to take the boom out of the
room, and it does

Whoops! Forgot to answer your actual question - I assume the "Dither"
setting you refer to is on "Page 2" of the "I/O" menu? Mine is set to
24 bit and sounds great, although I haven't tried turning it off. I
think 24 bit is the factory default. However I don't know if it even
matters if the Behrin
For what it's worth, I use the Behringer EQ completely in digital mode,

find it an absolute dream - and find that MP3's on shoutcast radio

Correction: we output 24-bits to both the s/pdif and the internal DAC.

Yes, but... MP3 is a lossy encoding. Our MP3 decoder does gene

I'll second Pat's comments: equalizers are generally frowned upon in
the audiophile world. I would skip it, unl
