Von Schweikert VR-6 or Wilson Audio Watt/Puppies 5

Regarding service for the VR6's, give Albert a call. I'm sure they'll be happy to maintain these speakers.

As for power, I'm driving them with a pair of modified Kronzilla DM monoblocks. These use the T-1610 tubes biased conservatively to produce 45 watts per channel. These SET output tubes will drive the VR6's to any volume to which I care to subject myself.

I find the VR6's to also be very revealing of upstreamm electronics, cables, etc. I once had loaned my Masterbuilt power cords to a friend, so was using Shunyatas. When I got them back and got my system set up, it just didn't sound right. I had accidentally not connected one of the Materbuilt powercords to the PS Audio DAC-II (instead to another secondary component). Once I switched powercords on the DAC, the problem was solved. That's pretty revealing.

I sold my VR5-Anniversaries several months ago to make way for new speakers. I moved my VR-6 speakers from my bedroom system into my main system for the interim. I'm amazed how good they sound with great detail, top end speed & openness, and robust, extended bass. They have the VSA quality of musicality, neutrality, and wide & deep soundstaging. The woofers don't have the same level of speed & control compared with the VR-5/VR-9/VR-11 magnesium woofers, but of course they're much less expensive. I don't have experience with the Wilsons, but the VR-6's have definitely passed the long-term satisfaction test with me.
