I am new here and I have just found this little App. Thank you very much for this, Triode! For a long time I was searching for a streamer beside the LINN machines that can handle 24/192 and Gapless. Now with your App the SBT with external DAC is able to do both, fantastic :)
I have just checked it with two DACs, a quite cheap ASUS Xonar Essence One and a quite expensive Grace Design m903. With both DACs the sound via the coaxial S/P-DIF seems to be as good as one can expect it from the DACs in the best case. Therefore I think the jitter of the SBT output is not very high. But it seems to be important to use a galvanic isolation on the digital connection. The m903 has very good transformers at its inputs and for the ASUS I use an external box, there the improvement on sound is quite significant. I tried the USB-Audio mode, too. This seems to be more difficult than the digital output. With a little trick after first installation a quick switch-on/switch-off the ASUS worked, but only @192k. It was not possible to correctly switch the sample rate resp. then the sound was distorted. 44,1 was sometimes played back as 48k, 48k as 44,1 or as 96k, 96k as 48k or it always remained @192k. With the m903 there was no playback possible at first. Then I tried a simple bus powered Hub-Cable between SBT and m903. Now it works fine incl. sample rate switching. Only, other than expected, the sound seems to be not really better than with S/P-DIF. But I have to do further checks Maybe the PLL of the Grace incl. the input trafo is a very good solution for S/P-DIF and thus a further improvement by asynchronous USB is not possible. On the other side I suppose that the ASUS would show improvements with USB because its PLL is not very good. Has anyone an idea why switching of sample rate does not work? Using the Hub as I did with the Grace does change nothing.
