Is there such a thing as too much power?

From my own listening experience, I have heard great examples of different types of amps so I hesitate to say what sort of amps sound best.  I currently own two pushpull amps--one a push-pull triode amp using a 45 tube, the other utilizing the 349 tube (tetrode, I believe).  I also own a parallel single-ended amp that utilizes 2a3 triode tubes.  Of the three, I favor the 349-tube amp. 

Of the candidates for best amp I've ever heard, I would place a custom-built OTL amp at the top--astonishingly dynamic and lively without being hard-edged and brittle sounding.  The only competitor, to me, is a push-pull amp running the exceedingly rare 252 tube.  I heard the 252 amp playing against an Audio Note Kageki (that is the parallel SET 2a3 amp I also own) both driving Audio Note AN-E speakers, and it was no contest--the 252 amp blew away the Kageki.

While my preference is for tube amps, I had a friend's First Watt J-2 in my system for two weeks and liked it very much. I could easily live with that amp even if I preferred my Kageki and the 349 amp.  That same friend built an SIT amp using the schematics supplied by First Watt for DIY amps; I heard that amp in his system and it was a terrific sounding amp as well.  

Tube or solid state, I like lower powered amps combined with high efficiency speakers.

Stand by- Krell is currently working on the answer. 

Current-ly. Get it?

Admittedly not much of a joke. But then neither is this subject. I mean, the idea anyone still thinks power correlates with quality is mildly entertaining.  But its no joke. Its just funny anyone still thinks that way.

@millercarbon Hey I own a 78 911 SC ! Not the fastest car out there, but like you said well designed to use the power that it has all day long! To the extreme I just sold my 96 911 993 Turbo that was modified 600,hp/595 lb of torque 
That car was amazing! Did I do the stop speed of 200mph......never! Did I race every boy racer out there.......never. But there is nothing like a owning a piece of well engineer equipment that will do everything that you want, and then some at anytime!
I own a Tube amp in triode 35 watts and sounds magical and also own a D class amp that has 550 watts@8ohm 650@4ohms&1,200@2ohms 
When I use the D class to drive my Maggies, they really come alive with soundstage,  inner detail and micro dynamics, even at the lower volume levels. I think I'm a power junkie!!

Not all Watts are equal.  That's why one 50watt amplifier may sound better than another 50watt amp.  We drove a pair of Dahlquist DQ10s with a pair of 80wpc Stax amplifiers to uncomfortable levels that a 300wpc Kenwood could not achieve.  Of course, in 1980s dollars, the Stax was $3000 more then the Kenwood.

I have experience on damaging speakers with Too little watts.  Driving them into distortion and all of a sudden, no tweeters.
