Hello,
If you can get your hands on the P5 they go together like hand in glove! Prior to buying it I used a Proceed Pre, Classe DR6, Plinius CD LAD, and Audio Research LS15. All of them sounded pretty good because the W5 is fairly easy to mate up with. But the P5 sounds like a Krell, Levinson, and Rowland combined in one. It is built like a tank. The only negative thing that I would say is that the imbillical cord from the separate power supply is not long enough!
