For Adcom and Hafler gear I recommend John Hillig of Musical Concepts. This sage has been around since the 80’s and his work has been reviewed by among others Absolute Sound and Stereophile. I just got my Adcom 750 back after the Elite Mod and it’s a whole different animal. John also did my Adcom 555 back in 82 which I still have and still works. I still have my modified Magnavox 650 cd player too.
Yes I have moved on to another amp and cd player but for their day they were worth the investment.
