Hey guys what's up? These are two particular amps that i would love to add to my collection some day, yet barely ever see....the older US amps seem to be more rare than the Soundtreams! I don't particularly want to spend any money now on collectable stuff now...i have done that enough already over the years, however a polished '98 era USA200 or USA400 (had one new in box round 5 years ago and sold) i would kill for, as would a Soundstream reference Class A 6.0 NIB (3.0 would be swell too but i owned one and never the 6.0) but there ya go, 2 amps which are either extinct it seems or no one wants to let them go...anybody have these in their collections? This is def not a WTB add....i don't have enough posts or money to make a purchase now but am very curious if they are extinct now!! I see more art amps than these by far and they're older!
