I think that you could only use the PS Audio at the 60 hz setting, or, if you get the Multiwave option, the PS2 setting (which is better, in my view, than the 90 hz setting), because of the turntable motor. That eliminates some of the options you would get with the P300, if you were plugging other equipment into it. I have a P300 and a Walker, but only plug the digital front end into the P300. The Walker is an effective unit; I like it because you can set the speeds precisely, and don't have to change the spindle on the TT (that, unfortunately, is how it works with my Basis. You have it easier with the WTT, because you just slip the belt down or up on the spindle. If you're just looking for filtering, if you see someone selling a Bylux filter for a WTT, that has a similar filtering effect and is less expensive (I have one I used before I got the Walker, but it's for a Basis, and I don't know if it would work for the WTT).
