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

All I can add is personal recent experience with a 500 watt Magtech amp compared to a my 70 watt cj tube amp. I was worried the 500 watts would be too much for my 90dB efficient Spendor SP100 speakers, maybe even blow them out. What I should have worried about was having to return the Magtech!  By comparison, The cj sounded so muddy and hazy, especially in the lows. For many years, I thought the Spendor’s were slow and had difficulty with a lot of more upbeat music. Now I know it was my under powered tube amp. The extra watts gave a much more overall relaxed, detailed, rhythmically assured presentation. I guess there is some midrange glow that the cj adds, but now it is very clear that this  effect is distortion.
