New to Bi-amping, Crossover and Tube amp


I have decided to bi-amp my speakers this is my first attempt, and I would appreciate some opinions. I was thinking of using a Marchand Xover and a Cary 120S for the highs, and keeping my beloved Cary CAD 500 MBs for the low end. I have Maggie 3.6R's and want some opinions?

What Machand Xover, or is there another suggestion? Also, is the 120S enough to power the mids and highs on the Maggies? I also thought about a VTL or Rogue, but I love the sound my Cary gear makes with the Maggies so thought I would try to continue the trend.

Suggestions and advice is welomed and appreciated.

thx.

I don't beleive this to be correct Ngjockey. In bi-amping the Maggies with an active external crossover, you do abandon the Magnepan external crossover and just use the internal crossover for the Mid's and Hi's.
As I said, I've never owned or worked on Maggies. I was just assuming the mid/hi xover was part of the external passive since there isn't a lot of room on the panel. Even better, no surgery.

I Should be more specific and point out that it's the Bryston 10B Sub and they are available in both RCA and XLR versions. Looks like the Marchand would be less expensive unless you can pick up a used 10B Sub.
Almost forgot about the Pass XVR1. Excellent and very flexible but costs more than your speakers. In the same price range, there's the DEQX processor/preamps that have digital EQ/room correction features and very steep slopes. Either are not simple to use but do not require changing boards.

At the other end of the scale there's the pro units like Rane and Behringer but it's debatable if they would be an overall improvement at your level of gear.
