i would not hesitate to buy *any* used melos equipment - i bought a music-director preamp used from the audio outlet, but they agreed to ship it to m.a.r. for inspection & any tweaking needed. i only *wish* i could afford to buy a pair of their stereo mat180's - i *do* want to bi-amp. but, due to known reliability issues w/older melos product, i would *not* buy a melos amplifier unless it went to m.a.r. for updates to known achilles heel problems they had. they also have sonic upgrades, which would be very tempting, if i had the money...
so, fbi - buy the amps - you'll love 'em! but, have 'em shipped to las vegas 1st... and, ttl2000, if your amps have not been to m.a.r., pack 'em up & send 'em, before something *does* blow up! ;~)
for solid-state amps, i love my electrocompaniets, but... anyone wanna trade me their melos amps for a mint pair of aw60ftt's? :>)
