What PC best for Modwright SWL 9.0SE Preamp?

Of the ones you mention, I tried the Poiema !!! and VD Nite II on my Modwright preamp. The P!!! is still there, while the Nite II powers up my Modwright 9000ES nicely. I also have a P!!! on the power supply that provied juice for the tube output stage on the Modwright cdp.

Bottom line, the P!!! synergizes very well with Modwright.

Wlo, the Poiema!!! power cord just gets out of the way and lets the preamp do its thing. I hate to overuse the term "neutral", but the P!!! is. It allows the preamp to soundstage big and airy, the midrange is spot on, and the bass is full and taut....no silver colorations to be found here!
