Sonus Extrema: Amplifier and room size


I am thinking about buying a pair of Extremas. I currently own a wonderful EAR 890 (70W per channel), and I wonder whether it is sufficiently powerful to drive them. Also, what is the minimum room size to enjoy the Extremas? Thanks

Thanks for the suggestions. My room is about 17x12, high ceiling...probably too small for them?
sory guys, these speakers need Power!!!! give it and you'll be happy, if not don't do it!
Kops, would you use a bi-amp solution? A powerful 200+200 SS for the low frequencies and a sweet tube like my EAR for the rest?
I cannot begin to tell you how impressed I was when I last heard these "CLASSIC" speakers.The amp,I believe was a powerful Modjeski tube unit....BUT.....the speaker DRAMATICALLY improved with the use of the Townshend Super Tweeters!!!I was bowled over with the tweeters employeed.I believe the stock tweeter rolls off a little too low(17khz).

My friend has just gotten the stunning Magico Minis,and IMO the Extrema/Townshend combo is a "serious" competitor for that "latest"(but superb) design,even though it is not the "latest" out there(who really cares?).

Sometimes when something is really good,it holds up over time.The Extrema certainly does that,IMO!!!...Gorgeous to look at as well,but this is ALL only my opinion!
