The MC275 is built like a tank that lasts forever. New ones are too pricey. I've seen used MC275s change hands for around $2500 on audiogon. A similar sounding tube amp is the more powerful MC2102 which uses much of the same design as the MC275 and comes with those great blue metres.

The Mac speakers are OK but way overpriced IMO. For price/performance the Axioms are much better performers. I'd bet dollars to donuts BB King plays Lucille better with the MC275 driving the M80s.
