Tpsonic, any reason the Conrad Johnson MV60 (55 watts/ch with EL34 tubes) or MV60SE (60 watts/ch with 6550 outputs) aren't on your list?
I have the MV60 and find it very musical with more than adequate power. (I listen to a wide range of music, though 95 dB average is the high end of my volume range. 80 to 85 dB is a more typical volume and the amp powers my 87 dB/watt Spendor S5e's just fine to the highest volumes I listen at.) The 6550 MV60SE might be the better choice for the top & bottom end, but there is certainly no substitute for the magic of EL34's in the midrange.
