I am powering them with a Rotel 990BX so about 320 watts RMS into their 4 ohm load. Plenty on clean power. I picked them up yesterday and so far I am flabbergasted, a pair of $3400-$3600 speakers for $500. these will be keepers and the sound is breathtaking. I have heard from some these were bright but I have noticed quite the opposite, just a great balanced neutral speaker that produces lifelike sound effortlessly. I will post a more detailed review latter, I also have some Sony ES SS-M7 speakers I just got that I am EXTREMELY impressed with and will give a review on those as well.
