My Marchand will be here soon... however...I'm curious if anyone knows of a 2-channel audiophile quality preamp with a built-in active crossover for bi-amping and/or implementation of subs.IRD is planning one (The Audiophile), but the development is on hold.Randog
I was also bugging Curt (as were a couple of others) to come out with a 6 channel preamp without processing to support 2-channel as well as multi channel music and HT. I'm completely baffled there's not one on the market.
Randog,Even tho' that good Aussie company DEQX have one, I don't necessarily think that combining your active crossover with your pre-amp is a good thing.I run an active setup - I've built 3-way active crossovers for my Maggie IIIas. This means I can have a (mono) xover box and 3 monoblock amps sitting right behind each Maggie - with 3 very short speaker cables.My stereo pre-amp, though, sits next to my sources - up the other end of the listening room.Regards,Andy
Hi Andy,I'm not sure the difference here. You can still have short speaker cables by making your long run from the crossover to the amp. It's either that or from the preamp to the crossover in your case. So it's basically a wash, right?Randog

It is the camp that believes in implementing a passive line level crossover before the amp rather than after the amp. If you split the signal from the preamp into seperate duplicate signals (preferrably seperately driven like the two outputs on the Purist) then you can replicate the passive crossover of your speakers in the line level with correspondingly smaller caps and inductors.
One thing I didn't mention is that I would still probably get a pro xo for experimenting even if I wanted to buy a Marchand xo. With Marchand it seems that either you have to buy their most flexible xo and lots of different cards for points, and sometimes you even have to prespecify the slope. I think it would be better to experiment with a more flexible xo first and when you are satisfied then order the marchand that best suits your needs.
