Aragon to Classe.....

Well, you'll have 300 watts a side @ 4ohms, in stereo mode (vertical biamp)...I'd go there. You could probably get rid of the Carver.

With the bass drawing the most power from the amps, vertical gives you more power supply at the ready. (you can try both ways of course).

I'm not sure I understand you correctly?

The stereo amps will act as mono amps...one left, one right. Each amp gets two inputs...left channel Hi/Lo for the left amp...right channel Hi/Lo for the right amp.

I'm assuming that each amp has only one transformer?...if so, you could have some extra headroom for bass reproduction with a vertical biamp, because each channel will have it's own transformer.

This may, or may not be the case?...as I don't know the Classe amps.

Of course you already mentioned another advantage that could come into play...I'll add shorter speaker cables to that.

Thats three "possible" advantages I can think of.

Dave

Well, you do have two amps for each speaker...each stereo amp is made up of two channels.

The amps are only stereo, if you run a stereo signal to them.

Shorter speaker cables could be better...and cheaper?

You can try biamping both ways...there may be no difference at all?, or at least not one you can hear.
