the jrdg models 2 and 10 are very different from one another, as much so as is the 10 is from the ayre. i would not buy either the jrdg 10 or the ayre without extensive listening time in my system, absolutely without exception. after all, we're not talkin' a pound of chopped liver here. IMO, the 2 may better the 10. but then, you may judge the ayre best of all. i've listened to all these amps in systems other than my own. they're all of very high quality and very system dependent. more than is usually the case, trust no ears but your own. good hunting. -kelly
