what amp under a grand?

Don't know your speaker's specs, your listening tastes or room size, but the Clones 25i is the best amplification I've ever owned and probably the most natural and non-HiFi sounding amp I've heard at ANY price. If you like room shaking bass and a lot of zip and zap, get any 200 watt, generic, run of the mill amp. They pretty much all give the same sensation: make u feel as though you're listening to a stereo system.

speakers are 90 dbw sens @ 4ohm, listening taste ranges from tool,slipknot,lamb of god, to nat king cole, seal.i pretty much listen to all music except for hip hop. room size i 15 by 19.

Well, if you hadn't mentioned the first three bands, I would say go for the 25i, its 25 watts double into 4 ohms. However, you always could go with Funjoe's higher output amps. His 50 watt amps double into 4 ohms, so 100 watts would've been enough for you. Your specs are slightly better than my own. I listen to mostly classical and jazz, but I haven't tried my Rage Against The Machine and Tool albums on it yet. Now I'm curious......

Well here is the deal, I can get a parasound a21 brand new with warranty for a great deal and the same with the a23. but with a good deal on the a21 its still very expensive 2k. and the a23 i can get for around $800 new. the only diff i see between the amps are power output and peak. andi would think the a23 being a john curl design along with the p5 pre would blow away my 2100 and 2250 combo.

Has anyone owned either of these amps? if so besides the obvious (a21 has more power) what is the diff between the two?
