    I'll try to contact him. I had to spend a lot of coin to do my pre/phono pre just to get the right values. Now I have a ton of R's that I will probably never use, and I don't have R's that would be handy to mod XO slopes:(

    If he is still selling, lemme know. Right now I'm leaning towards one of the Marchand kits, but I'm really taking a WAG that a 4th order LR crossover will work in my situation. Something like the kit on the snippet link would be perfect to fool around with.

    I just got hooked up with a Clearview active crossover. It's variable and does a great job in the rigs I have heard it in. When it gets here, I'll let you know how it works in my rig Mr. EarlyB.

    I did the Marchand XO in my pre. It is a simple cheap kit. He has a program to figure out the slopes in case you want to mod it. They come with the BB2134 OpAmps now. All you need is a PS. A rat shack 12-0-12 transformer is fine if you mount it out of the box. The Marchand PCBs are top notch too.

    Send it down with Russ in Feb I'll test it for you for free:) Actually I would love to have something I can turn a dial on to figure out where I want to fix my XO point at.

    Like this?http://www.behringer.com/EN/Products/CX2310.aspx Believe it or not I have heard reports of some using this inexpensive unit in very good systems with very good results. They can be had for $90ish.

    Yeah the balanced only input is a pain, but you could whip up some bal to unbal adaptors/cables in a jiffy.

    I have a car stereo XO that I used to use. It worked pretty well, but no 15-0-15. I don't know how that affects SQ, but it is good to be able to turn some pots to test with. I have a GSA-700 surround amp I'll post some pics of later. I am ripping the digital out and I took a 4 1/2" grinder with a cut off wheel to the board to steal the amps. That will be my new integrated pre DAC XO. The pot that came with the Adcom is a motorized 6 channel, and I am thinking of stealing the IR control unit from my remote volume control on my other pre. The amp section is like a 535 from what I can see. I may drive the tweeters for now with that and see what it sounds like. There are a couple naughty DC caps in the signal path that I may bypass or replace with better units. It will be for the highs so caps shouldn't hurt?

    Early, et al.

    Found a pretty interesting XO project on DIYaudio while researching for my project. Basically an analog XO unit that's adjustable for order, frequency, and Q. Also has balanced and unbalanced inputs/outputs. I'm just wading into the thread, but looking at the schematics and PCB layouts on the first page it looks pretty promising.
