whats the best amplifier for me??

if size and weight is a consideration then maybe you want something like nu-force or anotherclass t amp.

Nuforce are Class D amps, I believe. Good recommendation. I'd check out BelCanto's Ref 1000's as well (similar technology). You can always get a gym membership and work on those chalk farms until you can mscle a Pass Labs.

A few more details would help us help you:

-Which JM Labs specifically
-What are the other components of your system
-Room dimensions (Roughly)
-Price range
-Musical interests
-Preferred listening volume and sonic attributes

For starters

Search the archives for "class D" amps. Loads of info.

Research the Channel Island Audio D-200. It's a Class D amp similar to Nuforce and Bel Canto. There is a lot of information available about any of these amps. They are all light weight, cool running, and have a fairly small footprint. I auditioned the Nuforce - a great amp IMO - but settled on a pair of D-200's ... mostly due to financial considerations ($5,000 vs $2,500 new). I got a pair here on A-gon for about 60% of retail. The D-200's should work well in your configuration.

by a strange coincidence, the one i'm selling.
