Well please excuse my ignorance here but
The code for mov123 is online and can be read easily and IIRC there is
no processing of audio data except through QuickTime library calls.
That said, mov123 seem to use an older supported but not preferred

Where is your normal listening volume ? Your hopefully aware of that the
digital volume is reducing bits so the noisefloor is creeping closer.
What amp or dac is the SB connected to you could just try the volume on
that instead, and use the full volume of the SB to see if the problem
goes away.

Aaaa only for MP4 files then I'm totaly lost here ? (sorry i did'nt
notice)
but i'm strongly suggest that you fix the volume for the SB connected
to the AVR4306 this setting is per player so it won't affect the other
zones.
Drawback is that you have to use the Denons volume for the main rig.
I last note How do you transcode ?
mp4 is not native to the SB3 so it's trancoded on the server.
I suggests transcoding to flac.
this will be a lossy encoding to lossles trancode.
mp4 to mp3 tracoding is lossy to lossy and this IS known to introduce
artefacts.
check your file types settings.
Dynaudio rocks :-)) I also have an old model (the 3.3) but I am more
than happy with them.
Ok, so digital output is actually bad if I get it right. Reducing the
bits sucks. I am going to switch to analog. Maybe this will eliminate
the problem.

I would not say that digital out is bad I use that as the dacs in my
meridian is superior to the SB3, but i don't use the volume control.
So the digital out is the preferred output to HT equipment as most HT

including subwofer filter
The thing is... I want to use the volume control of the SB. If I have to

IMHO the problem is nothing to do with the OP's hardware. This is
obviously the case since he has no problems except with M4a files.
Also this is nothing to do with the SB volume/gain controls - you don't
get hiss by reducing the bit depth - you get a grungy sound at very
very low volumes.

Just to correct a few things regarding the volume control on the SB. Yes
it is digital, yes it works by throwing away bits, but the output is
24bit not 16bit and the decrease in SNR shouldn't be noticeable with
moderate use. The recommendation is do setup the amp so it's about
right with the SB
Hi,
to clarify:
These files are top notch quality. They play without any hiss on any
other player (like from within iTunes or on my iPod or through Winamp
on Windows). So it's only on the SB Duet where the files are causing
problems.
