Difference between New and Old Amp WPC ratings....

I own a pair of CV D-9's (I know this is an audiophile website, be kind, it's what I can afford for big sound). My question is this. Old amps, Marantz and the like have power ratings of 20, 30wpc, and newer amps have 70-150wpc. My CV's say they can take 300 wpc, and I have them on a Pioneer that is about 80wpc, and it gets pretty crappy as the volume goes up. Is there something about the wpc ratings of new and old amps that I need to know, or do I just need to get a PA amp to run these things?

Actually, I believe (not 100% sure) that there was another rule change subsequent to 1998. It actually had the effect of going the other way as IIRC it reduced the preconditioning stress and discoutaged and/or disallowed the power RMS @ X% THD over bandwidth spec that had been traditional. Someone with more energy might want to research it further, but the current specification regime is I believe less useful than previous.

Apologies in advance if I screwed this one up, but I'm pretty sure there's a kernel of truth in here smoewhere.
