I have 7's and have tried several amps. To my ears and a consences of other valued ears, 7's sound best with tubes. With good ss, the 7's do come alive at higher volumes but they also lack mid volume level "presence." The tube warmth tends to bring out the mid volume sense of music. The ss has been several versions of ML and the tubes different Sonic Frontiers with some tube roling with the output tubes. Hope this helps.

A superb match that will bring you to tears as well as rock you out is the ARC VS115 amp...a terrific bargain! I used the VS110 with WP 6's and it was amazing..suggest an ARC Preamp as well, even an older LS 25 would be great.

The PASS X250.5 sounds great with the W/P7s, with plenty of power. The MSRP is close to the XA30.5

The XA30.5 was under-powered on my Wilson Sophias, I went with the X250.5 + X1 (preamp.) and have been very happy with the results.

Lamm M1.2 reference are the only way to go with the Watt Puppy 7.

My experience with wilson speakers is you need some power behind them. WP7's can play very low and need the power to control the puppies.

I have WP8's and the VTL 450's and I think they are a match made in heaven. low listening levels they are very good, however Wilson speakers like to be played loud. I find mine really come alive around 75-80db.
