Bi-Amp Crossover Advice


I have 3 questions:

1)to finally bi-amp my Maggie 3.6R's I need a crossover and I am trying to decide between a Bryson 10b, Marchand 44 or Marchand 126. I plan on using the 2 amps and a sub, so I want to run one amp to the high/mid section of the Maggies and the other amp to the bass panel. Then I want to use the crossover to sum the low frequency and send to the sub (probably below 38hrz). I am shying away from the Marchand 126 because I have read several reviews that say it can color the sound, and I don't want that. I want to hear the amps, not the crossover. So any comments on the Marchand vs the Bryston??

1) I am keeping my Cary CAD 500 MB's for the bass panels, and either using the Cary 120s or (2)McIntosh MC275's bridged. I am leaning towards the Cary for continuity and cost. I am just wondering if 120w per channel is enough for the high/mid's? I am also thinking about the Rogue 150 MB's? Opinions on this set up? I like the idea of the McIntosh amps, I have always loved them, and even if the bi-amping doesn't float my boat, I would prob keep at least one of them, just because they are such awesome amps.

3) With the cost of this "improvement" should I just upgrade my amps to the Bryston 28sst instead? Net cost would be about the same>

Thanks.

Why not use a Dahlquist LP-1.It can be easily upgraded and isn't bad in stock form.
Are you talking bi-amping, in which both amps get the entire signal, and then feed the crossover, or do you want to go active? By going active I mean: the signal from the preamp is fed to an active crossover, which feeds the poweramps (each amp getting a limited frequency spectrum), which are directly connected to the Maggies.
Satch, I am talking active. Both the crossovers I mentioned are active x-overs.

Jallen, I have used the Bryston 14bsst in my system previously, and it is a special synergy. But to be honest, not the best amp I have used. My current Cary CAD 500 MB's I feel are a level above, and I thought the Innersound MonoBlocks were in the same league.

That is good info on the 28 Bsst's though, thanks.
Mac said, "I want to run one amp to the high/mid section of the Maggies and the other amp to the bass panel. Then I want to use the crossover to sum the low frequency and send to the sub (probably below 38hrz)."

Would you not then need a three way crossover?

"If the first 100db suck, why continue?"
The LP-1 is passive on top/active bottom.It sports L+R high/low outs and two summed/mono outputs (2 stereo/2 mono for subs).
