Spirit- you might also try an EAR push/pull amplifier as comparison to the SETs since the company is UK-based. It will provide some reference to your current auditions. 
What about 845 tubes on Wilson Sophia 3...?
Nagra was the PP 845 I had in mind....Melody also makes them. Im not a fan of Cary 805s and frankly, they measure terrible for SET.

push/pull 845 should work fine with them. i know the originals were spec'd at 30 watts or something like that. the only Wilson that is easier to drive is ironically the X2

Jordan- I concur with your thoughts on Def4s and power. I think 20-25 watts+ is necessary most rooms. Must be the multi driver aspect of the speaker.

Zesto/Vac/Tad- and by a mile

I've had it. It does some amazing things, but 10 watts was dynamically limitng even in my 100db Zu Definition baseed system.My biggest issue was that you get SET type bloom with SS decay- its sounds a bit weird after awhile.

Charles-I will get to hear the Valvets on the Dart integrated at some point soon, so will see how much more you indeed get at that price point. But yes, I always worry about diminishing returns at those elevated price points. I am starting to get ...

Charles- may be a cop out, but like them both. Although I am having rectifier issues on the Quads- the 274b is the best i have had, but not stable. I have not found a suitable 5U4G, and the RCA NOS in there currently are too warm which makes the c...

I use the 1.25x center to center as a starting point- but its all room dependent

Help with a system for a guy into electronic music
I love EDM and used to dj house music a few years back. I think Zus really work well for this genre- and Sean Casey loves EDM as well. Deepsky, the producer, even masters with them.I was listening to Tycho/Thievery Corp this morning as a matter of...

Bill- I didn't think either Vac was the best match for Zu. I had Def 2s on the Vac Phi 200 and preferred my McIntosh amps at the time to them. I feel the Quads are a better match- if they had a US distributor right now, I would feel more comfortab...

Tough question Bill-- the worst amp I've owned is the Almarro, I will say that.The Quad 40s have been my favorite amps to date. On the 845 side, I liked the Sophia the best, but did not have them for long. But I'm a bit different than other Zu own...

Some initial thoughts on the Valvet 3.5MKII monoblocks--in a word, transparent. However, without the issues that I've had with other SS amps (see my SIT comments). In fact, I would guess 9 out of 10 audiophiles in a blind test would consider them ...
