Amp to drive my AR-90s

I've got a pair of AR90's. I'm driving them with a Harman Kardon HK3490 receiver (120w:89ohms/150w:4ohms). If your source is a turntable, the 3490 is definitely enough power. It's around $400 new price. Mine is B stock which I bought from the factory on ebay where they are auctioned off for $229. There was a reserve at the time--they didn't call it a reserve, but you couldn't get it for less than that. The sound is really nice with the 90's. I like it a lot.

As much good clean power as you can afford ..... They are very inefficient and like a lot of power to sound their best .... The power really opens them up and is not just for volume ...

I am looking at picking up a used Adcom GFA-555 once I get my speakers fixed. 300 wpc into 4 ohms from what I've read...

That should work well ...

I ended up with a GFA-555mkII and a GFP-750 preamp. I've got all the speakers refoamed but one of the 8" is rubbing.

I'm thinking the spider might be gone on that one...look for a replacement now.
