Just want to make sure I am understanding this correctly -
While playing music it is not uncommon to have 10-12db peaks.(right?)
If an amplifier can deliver 100W rms into a load before clipping the signal, then to accomodate a 12db peak without clipping it, the amp should be playing normally at no more than 6.25W rms. Anything more than 6.25W rms would make the amp deliver more than 100W on the 12db peak and hence it would clip.
Am I within the navigational beacons or way off course ?!

The Crown Macro Reference amp was touted as the only true amp capable of 120dB of headroom!
It has a monsterous power rating of 760W @ 8ohms per side+++
This is an amazing amp from a specs point of view. the white paper on it was fascinating!
The output Impendence is so low, they were able to acheive a damping factor of 20,000!!!!! thats right 20K!!! most amps are what??? 100-200???
The white paper stated that the only way to effectively couple the amp to a speaker, without affecting the output impedance would be to use 00 welding cable or 2" copper pipe filled with solid silver!!!!
Now thats a monster!
Even the Big Boy Krells tuned there nose up at it!
it supposedly comes very close in sound quality to the big Krells, just a slightly recessed midrange from what i have read when compared to a KSA-250!!!
This is 2nd on my list of Dream Amps!!

I don't think so. How about 12db?
120dB dynamic range makes more sense. Yes.
In fact 120dB dynamic range is really impressive, if true.
To be honest, my own designs usually are limited much lower...
...already limited by the S/N ratio, where I typically range between
100dB ... 110dB.... (including hum)
Well, there is always somebody who can do better
@Percy:
I agree to you & eva & bill.
Average power load during normal music is far below the
peaks.
And that's the reason, why I do not really understand the discussion about some ultraoversized PSU. A discussion about a low impedance PSU would make much more sense in my perception.
Cheers Markus

This is why we are fond of high efficiency loudspeakers. If you really want lifelike dynamics, nothing else will do, especially if you want those dynamics while using a 20W JLH amplifier!

If you over design enough, just about any result can be achieved. When compared to cost?? Well, this is another subject.
