phase linear 500 watt per chanell amp

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!

Good clean power for about $1 per Watt! The series 1 amps were not that reliable, but series 2 was MUCH improved. I had a lot of Phase Linear stuff. Five 300 series 2 amps, none failed in 42 years of hard service! Even my 700 series 2 with all NEC outputs never failed!
