Think im gonna up my budget for my amp pre amp. Im looking at the Parasound a23 or the a21 amp, and the p5 pre amp. im sold on the p5 but unsure about the amp. would it be smarter to go with the a21 specs look the same except for the power supply of course.has anyone owned these amp?
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.
