Is powerfull Amps only for low sensitivity speakes?

Dear Friends,
The general amp advice for the speakers 92+ db sensitivity speakers are mostly low power amps and mainly set or pp tube devices. I wonder if you have any experience with a setup of high sensitivity speaker with 100+ watt amplifier. 
My speaker is va sarastro 2 and at the moment driving it with accuphase a60 power amp. I've an opportunuty to buy Arc Gs150 amp with a good deal.
thanks for your comments

The point is that with significant dynamic range the peak power required is much higher than the average. In the quoted example, if you need 1 watt on average, you will need 160 watt to cope with a 22 dB peak above that average.

So I guess you started the equation with a lower power requirement for average level, by e.g. using more efficient speakers and/or a small listening room. And 4 Ohm is also pretty low.

+1 - Agree with Trelja and Noromance

From my 35+ years experience in this hobby, power corrupts, and have your ever really heard how loud 1 watt/channel can get?  We only have 1 set of ears and I like mine to last as long as possible.  A lesson I was taught many years ago by a stereo shop owner who was tone deaf but built the most amazing sounding speakers.
