Do not want to veer off topic, but have you considered a SS alternative? I have a 47 Labs Shigaraki integrated, as well as a Final Music 6 battery powered amplifier. Both, the first with 20 watts and the second with 10 watts of battery power have surpassed my 300B amp tubed with WE matched sets in the resolution department. I think the efficiency of your speakers can match beautifully with the 47 Labs amplifiers. BTW, both are incredible quiet, something that tubed amplifiers have problems with. I think this is the new wave....this is no understatement for I have owned from high powered tube amps as SF Power 2, and presently own the Assemblage 300B Platinum edition, not a sloucher but cannot hold a candle to these newer amps. I also run a powered subwoofer with my fullrange horn loaded speakers. The Shigaraki takes 3 inputs and has a tape loop. I would not overlook the 47 Labs if I were you.
PS: My dream, when I move to a larger house is to pair my Final Music 6 off with a pair of Klipsch La Scalas.
