Tim, very interested to hear what you think.
I've compared a home built SET amp to my RWA 30.2 Signatures and I prefer the RWA power in every way. Better control, more dynamic, and more clarity of instrumental voice from top to bottom. The SET was fuller in the midrange, no doubt. But there was also a lack of corresponding fullness elsewhere.
Of course I never had something quite as nice as what you're using and I've never had a chance at the 2A3 amps. Really looking forward to hear your experience.
