My question is about bi or triamping.

Active multi-amping is quite common for pro sound reinforcement but is a bit of an oddity when it comes to home audio. As such, manufacturers build products for the market that buys them the most.

Having said that, Phil Marchand markets kits that will allow you to build the crossover of your dreams using the parts of your choice. You can substitute your own wiring, connectors, etc... using his boards or buy one of his designs in ready made form. There are also several other companies that make "audiophile grade" active crossoves, but i don't know of any that offer all of the various makes / models / versatility that Marchand has to offer. Having said that, i'd love to learn of other options in this market as my brother will be looking for a new crossover pretty soon. Sean

Hi Doc,

Take a look at www.crossovers.com. These folks can provide you with all the support you need if your budget allows. Good luck.

Doc,

I have a Marchand XM-9 Deluxe and am very pleased with it and active systems. The quality of the parts is fantastic, although they aren't much to look at. They offer 2,3 and 4 way, both fixed and adjustable, in both tube and ss. Sean is quite right about the ability (and perhaps desire) to use whatever you want if you assemble it yourself, wire, connectors, upgraded power supplies (My next project) etc, or you can have one built for you. Building one is very simple, it takes about 8-12 hours (I'm slow, I know). They come with RCA or XLR inputs and outputs, so you won't have to deal with the 1/4 to RCA adaptors, which you have to use with some of the equipment you have found. I had a Furman crossover prior, just to try out active crossovers and was sold on the idea. The Furman, although pretty good (I upgraded the OP-amps) leaves much to be desired, compared to my XM-9.

www.sound.au.com has some in the projects section. He only sells PCB's.
