Amphion Argon 3

The Argon will be plenty loud with 55w, as long as its a decent amp. From what I understand you can't go solely by efficiency rating, you need to look at the response curve which with the Argon turns out to be an easier load than the efficiency rating alone would leave you to believe. I'm not claiming to fully understand the principles involved, this is from what I've read. I pushed the Argons with the 60w Ayre integrated and they sounded fantastic up to higher levels than I could normally tolerate. Plenty of bass, I would listen before you run out for a sub. You may want it, but check it without first. Good stands are essential IMO.

Mattcone, did you ever buy the Argon 3s? Thoughts?

These are perhaps the best bookshelf speakers I've heard. Poor recordings sound terrible! This speaks to just how revealing these speakers are. I sold my n805s immediately upon hearing them. They are being run with an mc275 tube amp as I found them a tad bright with SS amps. I wouldn't hesitate to buy a pair.
