Maybe this is too specific for most people, but thought I'd share. Through e-mailing Srajan Ebaen, who seems to share ears with me, he mentioned one of his all-time favorite SS amps was the Amp-1.
Having a new pair of VMPS monitors and needing a bigger amp to drive them, I picked up a used Amp-1, which is a 1-input, 45 watt integrated. It sounds great on the VMPS's, and I decided to give it a whirl on the big rig.
Short story short, the Modwright pre and stock Clari-T toasted it (dual mono en-route back to Chez Smith). The AZ was tight in the bass and incisive in the mids, but the treble has a shiny glare that I didn't even know the Druids were capable of.
I haven't tried the Clari-T on the 626's yet. I think they're actually hungrier speakers than their size and efficiency would suggest. And, it would be a pain. It will happen eventually though.
And, changing course - the Tone idea is probably on hold. Looks like a pair of Definitions are in the cards in a couple months instead. You'll all be suffering my incessant cheerleading yet again.
