Since I'm working on the Snell EII at the moment, I put the CIV's back in place to listen too. These speakers have a tendency to be balanced from bottom to top, evenly balanced, but tilted upward as frequency increases. What this means is that the tweeter control is totally useless IMHO, because the mid sounds tilted upward too. This is where the Sovtek 5751 helps. Being dead sounding on the EII's, it sounds much better on these CIV's. This is still the VP130, with the upgraded power supply. The Sovtek 12AXLPS went bad and has been left out for sometime. I don't miss it at the moment. But I do miss the warm, fat sounding less revealing and relaxing sound of the EII's.
