Quicksilver V4 amps

I am not sure of the preamp yet... I am moving from an integrated into seperates again, and wanted to make sure I have the right amp. With that assumed (V4) I would first look at the Quicksilver Tubed Linestage... Any input from V4 owners there as well or perhaps other suggestions?

Bigkidz-

I do have the Quicksilver V4's (Ei KT-90 type III) tube compliment driving the Meadowlark Nighthawks. They are a superb match. For now I am using the Quicksilver line stage with NOS Mullard 12AX7's. I compared the line stage to the Rouge 99 Magnum, but it was in a dealer showroom, and the preamp was not fully broken in. I was also trying to get the most for the price point, as I wanted to upgrade my front end(s) and then perhaps look into a preamp such as a Supratek or such.

As for a comparison with the SF Power 2, I am afraid I can not be of much help. I have not heard it for years, and it was a brief showroom audition. I have owned the Sonic Frontiers SFS-80 and had extensive us with the SFM-160's but have always felt they were much more musical than the Power 1 or Power 2. The "power" line of amps always seemed a bit more "solid state" sounding to me. Both the SFS-80 and SFM-160s are built like tanks, and sound great. I have not had the chance to tube roll as extensively with the V4's at this time, and they still need a bit more time on the KT-90s to fully break in, but with that being said, at this price point for a pair of monoblocks (by the way, Mike Sanders measured 180 wpc output on the amps with the KT-90 before he shipped em) that sound this phenominal, and look great on top of it is a shame more people are not aware of the line.
