As Dcstep says above, you should be able to mix brands of amps and preamps. The only time it could be a problem is if the preamp has a high output impedance and/or the power amp has a low input impedance. For practical purposes, the ratio of amp input impedance to preamp output impedance should be at least 10:1, preferably more if you don't want to get rolled off bass and treble.
Mixing amps pre amps?
Now I have conrad johnson pv14L pre amp and also cj amp. I need more power and am starting the upgrade process. I am going to audition the classe ca2200 I think. Will it work well or is there a way to tell with the pv14L or should I also bring the cp5 classe pre amp. I just want to hear classe in my system to see if that is the route I am going to take. I may even go with the mono blocks. initially want to hear one of thier good amps and this is all my dealer has to demo.
thanks
