i recently purchased a pair of aw60ftt's to run bridged-mono in my system. haven't got 'em hooked-up yet - i have to conwert 'em from 220v to 120v. but, they will be replacing an aw100 & aw75 i currently use in bi-amped mode. i tink electro s/s amps are *great*, i won't switch brands unless/until i can afford the purchase/care/feeding of some mondo tube-amp monsters like the melos mat1000 mono-blocs. the aw100 is f/s btw... ;~)
while i have read good things about blue circle, i have no 1st-hand experience...
regards, doug
