OK, so this is a tangent, but I did want to address the Audio Note. Im not sure which one you have, but from what Ive read and seen, that is how I would build a DAC. If it didnt have valve outputs, I think it would be about perfect. And yes, this is preference and Im not knocking your choice.
From my perspective, I would expect the best sounding PCM reproduction would come from a 16 bit DAC, with no oversampling and no digital filtering. If I didnt dislike tubes, Id buy a lampizator setup...no questions. Its the purest design, IMO. But I dont want to deal with tubes.
If the source is defined by 16 bits, then thats the most "sound data" youre going to be able to get out of each sample. If you effectively reproduce the waveforms, then there is no real need for processing or filtering, except maybe a brick-wall around 16 khz. Yes, there are crappy recordings out there with a lot of emphasized high-end "glare..." So just dont buy those :)
OK, Im going to stop now and not get on my soapbox about this upsampling/upconverting trend for 16/44.1, or Ill just get frustrated.
I actually like the PCM -> PWM conversion idea better, like the NAD m51, if youre going to process it so heavily, as I think it would reduce the filtering requirements. So Im surprised I didnt like it more at the shop. I think I need to hear it at my house.
Anyway, this got long. Apologies for the quasi-rant ;)
