Too Much Power

...referencing back to @mapman ​​​@carlsbad, the bulk of your listening is done at <5wrms.  At that level, you're already peaks into 100+...and beyond if that's your amps' available power....

Which is what it's about, roughly.  A tube class A into efficient speakers seems to have more 'bark to it's woof', whereas A/B tubed a bit less so.  But the price one pays is heat and shifts in 'character'...imho...

Into SS amps, less heat but into the Silicone Sound....love it, leave it, or just enjoy the differences.  More or less, what I'm about. *G*

D is OK at the lower $ levels, but the improved (& more $, generally) versions are obviously superior,   And no heat, unless you're riding it hard & putting it up wet...

The lower wattage ones seem to 'soft clip', but that's just an absurdvation I've made.  Your results will likely vary...Damage?  Perhaps.....

I used to own this nifty little box that registered VU and RMS at the amp output
16ish leds', labeled for both.

Listening with 150 a side in a 12d x 20w x 12h roof, most was 1~2 wrms with the peaks flickering at 100.

Any louder required leaving the room or earmuffs...SOP for 'room eq time'. *S*

Power hinges on driven into the given space v. the visceral experience you desire at high levels.  Simple... ;)

A good week, gentlefolk...J

Never too much power. 
 

  The sound will be effortless and open, airy etc

my speakers are rated for 250w and have never sounded better with a Sunfire 600:sig at the helm!

 You need the power. Get power and don’t look back

would need a lot of time with a D amp.

have demos a few, not my thing, a/ab is the way to go.

if you like the amps, go for it!

I find that with many S.S. amps, the best sounding amps tend to be on the lower power side. Probably has something to do with the number of outputs and the complexity of the circuit. All things equal you can never have too much power just a case of how this extra power sounds and how it is created.

Thanks for all the comments thus far.

Any thoughts on Audio By Van Alstine DVA M225 mono amps? These are small, high power, appear to run relatively cool, yet class A/B...

They ever a showman Bob Carvar did a video once showed the power required to reproduce the sound of a pair of scissors doing one big snip. I think it was a short transient of 1,000 watts. Anything less clipped.

But that is the point of massive power… not in plying loud but delivering enormous current for short durations so not to compress the music. I have usually owned amps of twice the maximum power handling capability of my speakers. They always sounded better because of it. Typically with a real high current amp you have to turn the volume up less to sound satisfying.
