I have no clue. I do not have much experience with flea watt amps. I have a Kenwood 18 w.p.c. tube receiver. It sounds good with the pair of DCM speakers I have. They hit 97db with 1 watt!! And they sound pretty darn good.
I would look into some of the vintage Klipsch speakers. They do well with little power. I am sure that some other members can recommend some speakers. I know someone on here was using flea watt amps, but the name escapes me at the moment. (to many prescription narcotics has my brain in a daze) Hey, that may be a great user name.. Braindaze.
