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

Obatu, don't just get caught up in the amount of wattage needed for the sensitivity. Yes this is important, but only half of the question/answer. As you have impedance also to deal with as well as negative phase angle. These mean how much current is going to be drawn from the amp, not just the wattage.
EG: As you can have a pair of speaker like Wilson Alexia which will be driven to sound far better with a 25w ML2 monoblock than a 1000w amp that has not much current ability.  

Cheers George

But...SET/DHT amps using tubes like 2A3 and 45s in these flea amps can sound so much better than a 300watt bank of transisters.

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.
