My ayre v-5xe is 300 watts into 4 ohms, but most good 150 watt amps will do near this. I would agree the bass sounds softer a LITTLE with my ayre then my bryston, but Im not sure thats a matter of power. Brystons are known for bass/midrange, and a little bit forward/punchy sounding.(havent heard/owned the sst yet)I will say if Ive ever owned a speaker that didnt need lot of power, this was it. Even when my 8bst lost its 2 left channels and I used it as 120 watts x 2 (8ohms) it still sounded amazing, and litterally easily played 95+ spl. The ayre took my legacy focus 20/20's to a level I havent heard in audio. I didnt know it could be that clean, and the soundstage while maybe not as deep as some electrostatics Ive owned, Had the widest Ive heard. Incredible. And I found I could tow them in much more then any other speaker and still get this wide soudstage effect with a spooky dead center sound when the musci called for it. If I played around with bi amping and a eq for the sub portion. Id love to try a powerful amp to boost the lower end. I read a review somewhere online with the focus 20's using the steridian(I think thats what its called) that the whispers use and he boosted the lower 25-20hz section and said it took lots of power for the speaker to play +/- 3 that low. That would be truely cool and totally eliminate a sub, for any music, and even MOVIES!
I wanted to say thanks, reading all your positive reviews was one of the many reasons I purchased my legacy 20/20's when I was looking at different speakers.THANK YOU!
