I'm pretty sure that amps have not hit the point where they can't and won't be improved upon. But, while I'm sure I'll find a better amp, and am currently looking...I'm keeping my MF A3cr anyway, because I would rather have that amp then the $600 I could sell it for. So it's a keeper. The same goes for my B&W 640s. I already upgraded to new speakers, but I'm not giving up the B&Ws for the $400 they sell for used. They're worth a lot more than that to me. Maybe I'd sell them to a friend over give them as a gift, but other than that, they're both keepers.
