For those that are truly bi-amping, what electronic crossover are you using before hitting the amps?
I've been using an Ashly outboard but fear that I am introducing more noise to the signal that I need to with this unit.
Just seeing what's out there and what real experiences people have had with other audiophile units.

Everyone seems to be using the Behringer dcx2496.

I'll stick to my Ashly XR before even considering a Behringer piece.
Any consumer pro audio pieces out there that defeats self noise in the pcb?

never heard it but that Bryston x-over looks absolutely bad-ass.

The bryston gets awesome reviews. I would like to try that or one of the Marchand tube crossovers.
VSA recommends passive over active biamping because the way the speakers are designed there should be an overlap. The rep specified a wide overlap should I do active. But I want the benefit of splitting the bands so that combined peaks are lower. So I'm using a sort of hybrid approach. I feed the lower band SS amp directly. I feed the upper band tube amp through the passive filters that I made for my vandersteen subwoofer. So the SS amp is seeing full range signal and the tube amp is seeing everything above 80Hz. It sounds great but I don't really think that the sub filter is doing a lot.
If you can solder, look for a bi-amp thread I started last summer. there are links to tube based designs and a couple of SS designs that get good marks. There are PC boards available for both designs if you prefer that type of construction. The Marchand can be had as a kit but you can get a lot of money into that thing if you buy the dual mono torroidal power supply.
I've heard lots of people say passive is the way to go because no crossover will ever be truely clean. Have you tried passive?

Here's a marchand that came available on agon for a decent price.
