How Much Power is Enough?

I'm thinking of upgrading my YBA 2 Alpha HC amplifier (70 wpc). I'm currently using PMC OB1 speakers that are fairly inefficient at 87db. I really don't play my system at very loud volumes...and I don't think that I'm stressing my current amplifier...but I'm not sure. I'm looking for an amplifier that will bring about a wide soundstage, tighter bass, and exceptional smooth execution of mirco-detail. Would having more power make much of a difference? ...or should I be looking at a higher quality amplifier and stay with lower power like my current YBA? Some amps I've been considering on the USED market are: Pass XA60 monoblocks (lower power), Pass X150.5, SimAudio Moon W-5....
Would these amplifiers be a good match for my system? Would it be an upgrade from my YBA? Any advice or discussion would be appreciated.

Your speaker are probably some of the best. From what I know, PMC's demand fairly high power to get the most of out them. I'd suggest you contact PMC, get the name of one of their reps and pose this question to them. Of course, your dealer may have the answer too, although they might be anxious to sell something they have. Your on the right track though. Seems like the only way to have speakers like those is to power them correctly.
