i am using a 555II with great results, and it drives very low impedances easily.
Contrary to the assertions others have made here, I found the 555II to be fairly warm and rather "earthy" sounding with my Maggy 1.6's. I bought the amp for $305, (hull of a bargain), and sold it for $350.

Relative to more expensive amps I've own, (Bel Canto and Monarchy), the 555II was a tad grainy and lacking detail on the top end, but there was nothing raunchy about that I could hear.

Today I run the GFP-750, (top of the line), preamp, mainly in passive mode. The only thing wrong with it, IMO, is a rather boring appearance. I like the balanced outputs that I use to drive my current Monarchy amps.
