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

I hope you can listened to the GS150 in your system first before buying" what is it you don't like about the Accuphase A60 anymore.

Kosst_amojan,
I completely agree with your comments. Those who recommend "the more power the better" promote and provide misinformation . So much depends on the design and characteristics of the specific speaker. Some speakers will clearly sound much better with tube amplifiers driving them and/or lower powered simple circuit class A  solid state (for example, First Watt or Valvet, etc.).

On the other hand some  speakers will definitely require amplifiers capable of higher power or higher current delivery. The load characteristics of the speaker is the vital determinative factor. To suggest that any high power solid state amplifier that measures well will be all that’s needed for "any" speaker is poor advice and in my opinion a disservice to those seeking meaningful advice. Kosst_amojan I hope people take note of your well reasoned reply.
