i love my electro aw60ftt's, presently used in a vertically bi-amped set-up. completely trouble-free. they replaced an aw75 & an aw100 which i was using horizontally bi-amped. the aw75 i bought new, & it was also trouble-free. the aw100 was bought used, & a power-supply cap failed shortly after i got it. i suspect the amp sat a long time prior to my using it, because the same thing happened to an adcom amp i let sit for a long time prior to re-use. this is a common failure of un-used amps... heinz preiss in florida fixed it for me, & it was trouble-free ever since. (i sold it about 6 months ago). i also have an electro ec1-a (circa 1988) that has been trouble-free. it will get paired w/the aw75 for an auxilliary system. until i can afford the care-n-feeding of mondo tube amps, i'm stickin' w/electrocompaniet.

btw, don't forget to get a tubed preamp for your 2-channel audio; especially since you have a digital-source based system. if h-t is crucial, find one w/a h-t pass-thru loop. suspects to consider are arc, vtl, sonic frontiers; i'm sure there are others...
