Wilson designed the Sophia to be easy to drive and at one point even demonstrated them being driven by a Naim integrated amp to make the point.
Absolute Sounds were kind enough to set up a pair of Wilson Sophia 2 speakers in our living room for us to try for a couple of weeks. The amp was a fully serviced Naim 32.5/Hicap2/NAP135s. At the time, the Sophias were clearly the best sounding and thoroughly musical speakers that I ever heard at home. Sure, they revealed the ultimate limitations of the 32.5 pre-amp, but in a very gentle, endearing way, so music was always highly musical & enjoyable to listen to through this system.
Since then, the pre-amp was replaced by a Naim 52/Supercap, so it would be even better now.
In the end, my wife vetoed the Sophias, as their appearance was somewhat marmite-like. We ended up buying a pair of ART Alnico speakers, which are equally or even more fab. They are British too and I'm delighted to support the domestic industry.
In short then, a 252/300 will drive a pair of Wilson Sophia's easily & beautifully, so long as you like the way that this amp presents music. I've not heard a system with a 252 that I enjoyed, which is why I went for the 52 instead. YMMV.
Hope this helps, FT
