Recommended crossovers for Maggie 20.1s


A number of contributors to these forums have voiced dissatisfaction with the stock Maggie crossover units. So what do you recommend as a replacement that would provide noticeable improvement? The Mye Stands have helped a lot, I could get larger amps (using Krell fpb 350 monos) but don't know a thing about crossovers.

Puerto, 20's and 20.1's always sound better when biamped with an active x-over in my listening experience. I would recommend the Bryston x-over, I use it in my system, which I believe retails for around $2800.00 these days. Also take a look at my recent review of Martin Logan Depth subwoofers, used as a pair, that has brought my 20's to much higher level of performance across the board.
I had the Marchand solid state, which was just OK. I suspect the Bryston is better, and the Pass Labs is better than that if you have the $$$. I haven't hear the tube Marchand. I ended up with a 2-way custom Xover made by Tom Tutay. It wasn't cheap - but it was GREAT! Really opened up the system. Ultimately sold it all because the Maggies were too big for my room.
Thanks much to each of you that responded. I will check out the Bryston product and follow-up on the related thread on Audio Asylum.

I know I own one. Used with 20.1 for 5 years.
Bryston 10B is entry level and the only reason I didn't get Tom's cause it fitted without balance.
