I’ve just finished restoring/tuning a Yamaha Pc5002m, better than spec and 8.5 looking. I’ve two driving the music section and a Pc4002m on the movie section. Certainly I’ve head room, no strain for anyone. The 5002m’s are truly audiophile be it in PA clothing, a marketing decision a.k.a. 101m reface. All three have had very time consuming and detailed refurbishing. Not a lot of technicians can or are willing to work on these, the detail justifies their spec sheet. Old to some, boat anchors to others, missing the bells and whistles of modern…time spent (hobby) irrelevant, its about the sound quality. The make doesn’t matter if it’s liked and breaks ya fix it new or old.
Cheers
