Aragon to Classe.....

this would be a huge upgrade. not sure on the power required for the vmps. if you run the amps in mono, you should have enough. my ca-200 amp goes from 200 watts in stereo to 700 watts in mono.

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).

Thanks for the help, yes vertical would be ideal to give less signal creep (I think) I just wondered if its odd to run Vertical when Lch would say be for bass and Rch for mids and tweets......is this ok or go Horizontal so bass is isolated to one amp and mids and tweets to the other?

In horizontal biamp, both channels of one amp are responsible for bass in both left/right speakers, so that one amp is exposed to the heaviest load while the other amp is loafing only being asked to drive the mid/tweets of both channels. In the verticle mode (one amp) is responsible for the bass in only one channel plus the mid/tweet of the same speaker. Therefore the load on the amplifier is reduced. Also, when operated in this manner you are running the amplifier pair as stereo amps and not bridged which may present a problem with very low impedence speakers.

I would also take the Classe over the Aragon for sound quality.
