Hi Waxer,
Is it possible for you to try a different Wifi adaptor (say a USB
802.11G)and tell us whether the sound is different?

Kuro,
I think we may be at cross purposes here. Are you driving a DAC with
the transporter? or listening to the transporters analogue outputs?
While I still can't see how wired vs wireless would make any difference
(all other things being kept the same), I can see how using the word
sync input
See page 5 of this post. the Transporter is a 4 bit DAC with
sophisticated pre DAC up-sampling filters and dither algorithms

Which upsampling filters? As far as I know the transporter does not
upsample at all (?)
If you ment the DAC filtering, then yes they will do their job as well.

By the way, there already is a nice collection of graphs on the sox
website that shows the impulse response for different rate parameters
when upsampling from 44.1 to 96 kHz.

Sure I will! However, the differences were small (or maybe I was tired
yesterday..) and I was not able to draw any good conclusions.

This is totally wrong. There is no PLL and that is NOT how network
streamers work AT ALL. (although it has been done that way for satellite

This theory needs more than a cup and a water tank to prove it, sorry.
No digital output is jitter free. Big Ben or whatever, you can only
