Hal, first of all congratulations on owning a great pair of speakers. When I was auditioning speakers several years back, I just loved the Sophia 3s. For what its worth, the Sophias I auditioned were driven by a BAT ss amp. I heard Watt Puppy8s the same day driven by a pair of BAT tube monoblocks, and I much preferred the Sophias with the SS amp. I love tube amps, but the Sophias driven by SS outclassed the Watt Puppies driven by tubes on that day. One of the most musical systems I heard.
