SET with inefficient speakers

i've always wanted to hear how an SET amp would sound at home, but my speakers aren't a good match in theory. they are dali euphonia M4's. floorstanding with two 6.5" woofs. 88db 4 ohm.

however, my listening room is smaller (10'X16'), i sit very close to the speakers, and i don't listen very loud (usually around 80 db level, per recent fooling around with the radio shack meter).

anyone have success with low powered tube amps under similar situation. there is no loacal dealer to do an in-home audition, and i don't want to hassle with different speakers. thanks....
