Thanks for the info on the decoding Currawong. I more or less got to that conclusion but glad I see it confirmed. I don't suppose asynchronous USB works differently?
I don't care much about the headphone output of the DAC but don't mind having it if only it were to have a different flavor.
The DAC would be connected balanced to the P1-u with the option of connecting it unbalanced to another headphone amp. I have the HA5000 or HA5000ANV in mind for now.
It would be fed from an iMac via USB.
I see you tried the DA-200. How did you like the DAC part?
Concerning the PWD, not a bad word about the SQ.
I was living at an apartment at the time but now we moved and my setup changed.
There I had my speaker and headphone system both connected to the PWD.
Now I have my speaker system in one room and my headphone system with my computer, thus the need for two DAC's.
The main reason I sold the PWD though is that I needed it to be able to read ALAC via network streaming which had always been promised by PSAudio, but alas they didn't keep their promise. I preordered it long before it came out. Wasn't to happy with that, so I sold it.
Now I'm streaming via Airplay to the Marantz NA7004 for my speaker setup, not the best method since everything gets downsampled I believe, but I plan on connecting a MacBook via USB to the NA7004.
So, a separate system for speakers and headphones is what it will come down to, using a shared library of course.
