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.
