Sounds like you're leaning towards SS, but if you can find one, I have been using a VAC Avatar (original, not upgraded). I can't compare with other amps, but you get an integrated with 30 watts, switchable ultralinear/triode, phono stage, and a home theater bypass to allow for use with, well, home theater. I believe you can also bypass the El34's and use a separate (SS?) power amp.
I've had mine for many years and had the good fortune of getting it on EBay for $1500. With the volume knob starting in the 7 o'clock position, I average about 10 o'clock for cd's and around 11 o'clock for vinyl.
The M3's made me upgrade my power cords and speaker cable since they are easily heard.
I LOVE the sound, soundstaging, etc. and am considering upgrading to the newest Triode version, but am waiting for reviews here. If not, I will happily live with these. Good luck!
