PMA-777 is impressive for vinyl and CDs; seems to go cheap

This is a superb integrated amp for vinyl and CD's!

This is the amp that got me back into vinyl with a vengeance.

I picked up a silver-faced, wood side-panelled PMA-777 with a matching Denon TU-720 AM-FM tuner in August of 2014 at a local Goodwill auction for $80 for the pair. I had a pro refurbish them immediately and have been enjoying the PMA-777 virtually every day since.

This a a terrific amp for vinyl and for CD's. Plugged into the PMA-777, I have a Denon DP-47F turntable with a Denon DL110 MC cartridge, and I couldn't be happier with the sound.

Likewise I have a Denon DCD-2560 plugged into the PMA-777 and I've never heard CD's sound better.

"A" speakers are refurbished OLA Advents. "B" speakers are refurbished Beovox 4702s.

Shortly after getting the PMA-777, I came across a PMA-770 for $100 and bought it for a setup in the garage. Technically, it's probably not as impressive with CD's, but sounds just as good as the PMA-777 with vinyl, with only slightly less apparent power.

For a low-budget setup with used 1970s-80s gear, my ears couldn't be happier with the PMA-777 (or the PMA-770).
