A 100V cap is plenty with that receiver of yours. A 50V cap is adequate actually. I don't know what to make of that.
It's not just me saying that about the M3v4 vs. M80v2. It's all who have heard both at my place. True enough the M80v2 has clearer mids, can go lower and sound louder but none of those things add up to a better experience than the M3v4. The M3v4 has a wider and deeper soundstage. Sound comes from instruments placed on that soundstage and it's not "thrown" at you like the sound from v2. The degree to which you can achieve this illusion depends on your room and placement within the room. The wider apart and deeper into the room, the better. If you can do this in your space, the M3v4 might be an upgrade over your older M60s. Oh yeah ...there's also the v4 tweeter. It just can't be compared to the v2.
