Why has amplifier power become a big issue

Back in the day I drove my Advent speakers that were very inefficient with 30 watts per channel. Today I run Vandersteen 2 ce speakers which are more efficient then the old Advents with 50 watts per channel and way more current. By most this is underpowering the Vandersteens, what has changed?

I agree that some (most?) of the complex multiway speakers can sound more authoritative on transients with more watts. But for the same dollars, a lower power amp may sound more musical.  There are now amps that combine musicality with big watts, but it can be an expensive proposition.

It's always been an issue.

I burned up my share of tweeters in the 70's with an uninformed mis-match of inefficient low impedance speakers, low powered receivers, and a desire to have Who concert levels in my listening space.

Erika I learned that lesson early back then as well. 

Also that the larger amps in any particular line ALWAYS sounded better.    Not even just with the biggest thirstiest speakers that needed them most.

I have found that higher power yields more headroom, if this is a need in your listening room?
