This combination works very well in my 8 by 10 room. Most of my listening is Jazz and acoustic music.

That is an interesting combination. Much like what the British were doing back in the 70s. I've driven a pair of Spica TC-60 speakers, 84.5db sensitivity, with 12-20 wpc tube amps in my bedroom system and they sounded great. Did try them with my Inspire SE EL84 amp and while the mids and highs sounded good, that amp didn't have sufficient bass power (the OPTs in that amp start rolling off at 80Hz) to produce a balanced full sound. With better OPTs it may have worked.
