To Tony,
If you like the sound of the older Esoteric gear than I would recommend using p01vuk which sounds better and complements better d01 than p03 you own.
They are still one of the best in the world and they have very well proven sonics. As you know most well respected Esoteric recordings used D01 in the recording process as the dac.
Since they are voiced together it is better to go for the natural partner. I didnt like the new dac with p01vuk that much. But it was great with p02. On the other hand the p01vuk sounded great with d01 or d03 (d03 is for sacds to do pure dsd)
