joe b, here's a shameless plug for a s/s amp if ya like toobs - i have an older electrocompaniet aw100 that i'm asking $800 for here on a-gon (orig retail - $2400)- as i have gotten little interest, i'm willin' to entertain reasonable offers... ;~) i'm currently using a matched pair of electro amps in a wertically bi-amped set-up. this will have to do until i can afford the purchase, care-n-feeding of a pair of melos mat-180's... ;~)
regards, doug s.
ps - while i have no direct experience w/yba, like sugarbrie sez, this company also has the reputation of toob-like s/s...
