phase linear 500 watt per chanell amp

I lived with one of those. It was amazing... ground breaking for 1978 (?)... but unrefined and noisy by today’s standards. it’s been a long time, but I doubt it sounds better now. .

For most of my time as an audiophile Carver was out there doing wild and crazy stuff... like his tiny cube. But for much of this time it was unique but there was some flaw that didn’t put it in the high end... noise or high frequency hash.

Great amp in its day however its ancient history now.

@roxy54, yes, i still have my mc602! one meter light went out but it's too heavy to take it to the shop to have a bulb replaced! LOL!

That Mac is a great amp...I would love to own one. 

I love the D-500 amp, good amp, 1/2 the weight. Think it was designed by A.P. VanMeter who once worked for McIntosh. I know for a fact that the 300 series 2 was designed by AP. You should get your Mac serviced, pay someone to take it to a reputable shop. The Mac is better in my opinion!
