Mixing amps pre amps?

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.

I'll check th manual on that. What about the fact that cj does something like inverts the phase or something. does this matter.

My system is the CJ 14 with Classe CA-150's. I like the combo of tubes with the SS amp/amps. The sound is great for my listening room and music tastes. The bass is full and tight and the joy of tubes is there in the midrange. Hope that this helps. Steve Levick

I've got a C-J CA200 that inverts phase. When you use most C-J you have to reverse the positivie and negative at the speaker or amp. If you put a component in that does not phase invert, then you'll not need to switch positive and negative.

Getting the absolute phase of a system right is something that many people don't get right, even though it can improve the sound. Trial and error is the most common way to determine absolute phase, since each component in the chain has the potential to invert or not invert phase.

In other words, it's no big deal whether a component does or does not invert, you'll just need to put it in the system and try it both ways to see which sounds best.

thanks, Hey salevick what speakers are you pushing with the cj and classe mix? I may get classe or go back to cj. classe 2200 or even the mono blocks. cj et250s or premier 350. If I do decide on classe I may also audition the pre amp as they have it as a demo also. with cj I would definately stick with the pv14 although cj informed me they are coming out with a new preamp which is a descendant of the pv14 that is specifically meant for the et250s. Who knows, currently don't have a cj dealer here have to go over one state
