What amp/amps to drive magnepan 20.1's


Just purchased a six month old set of M20.1's from a dear friend who left oversea's for an open ended work asignment.He had been powering them with a pair of VTL 450 mono's who he had promised to his brother. Question; I have a pair of bryston 7bsst's that i have been hoarding away in anticipation of the comming of my inherritance, and now i feel i can further my debt to income ratio by buying something else.
1.should i buy another pair of brystons and passive biamp ? active biamp with 10b bryston x-over ?
2.Sell the mono's that i have and get some used pass x600's or big mcintosh 1201's ?
3.keep the bryston mono's and put some big tube's on top end with brystons on low freq. with active x-over ?
I have about 8k. until i'm sonic'ly rich but cash poor Please help me before my senses kick in !!!

I'm in the process of biamping my MG 20's with 4 VAC 220 Monoblocks and a tubed Marchand XO. I'll let you know how this works out in mid-Jan after my 2nd pair of 220's return from a factory update. Goodluck!
I've seen a number of threads posted on the MUG forum about biamping with ss/tube combo's, but I am afraid to mismatch the amps. I even sent the second pair of 220's back to VAC to have them matched to the specs of my first pair. Several biampers informed me that the more I used the gain controls on the XO to match the amps, the worst the output...I really don't know how true this is, but I thought it easier and safer to stick with similar amps. What XO do you plan to use and what crossover freqs/slopes?
