There is a nice thread here on audiogon. I think there were some answers to your questions there. Please try to find this: "http://audiogo1.iserver.net/cgi-bin/forum5.pl?bsyst&968284191&read&3&4&&" or search for its title "Best speakers for 2A3 SET amplifier?". I've got a 3-5 watt SET and have found out that with 90dB speakers I'm happy at levels that would not disturb my neighbours (about 80-90 dB SPL at 1 meter). Have not heard the Sonatas but they are 2dB more efficient than the Sonatinas so they will probably be even a better match (provided the impedances are OK). If you do find out - please let me know - I'm interested to find out myself: the Sonatas/Sonatinas look very appealing from the reviews I read. On the other hand, I seem to notice that people that are happy with them have mostly SS power amps, so there might be some clue there (see www.audioreview.com) ... Kocho
