I agree Triangle, the 35 watt Cayin integrated is a hell of a piece. But allow me another name in this discussion, Quicksilver. As a B&W owner, and a new Quickie owner, let me add that they straddle the SET and push-pull sound. They have none of the overipe sound I sometimes hear in SET's and the ballsy sound of push pull. The V4's will be my last amp (probably more than you wish to spend but the whole Quickie sound is found in less pricey models).
