Bi amping a pair of B&K ST-140's

Hello all. I am building a second system and am looking for a pair of B&K m-200 monoblocks. I cant find a pair so I am thinking of bi amping a pair of st-140 amps. My pre does have two sets of main outs. Any other ideas? I thought of the adcom 565's, but I have always liked the b&k amps and their sound. Other thoughts were a b&k ex 442, parasound, rotel, etc. trying to keep cost under $1000. They will be driving a pair of b&w cdm7's.
Thanks all!

I have the older ones, plus I have one of the newer ones that I use for a center SPL. The old ones are one of the best values around.

The difference is mostly packaging afaik. I also had mine nodded at musical concepts.

The guy that has them is asking $850 for the pair. Is that way out of the ballpark in your opinion?I really want them and know I cannot go wrong buying them, but I also don't want to overpay.
Thanks

Also looking at a nice Ex442 sonata. I'm thinking that would also be plenty of power for the B&W CDM 7NT's

850 is high. I've seen them as low as ~450 in rough cosmetic shape to ~700 in good shape.

I'm not familiar with the ex442.

I'm in agreement with all of the above.
The older, original lower powered 70 Watt ST 140's were a bit better into lower impedances than the later 105 Watt ST 140s.
Having had both the ST 140 and M200's in my system, I can verify that they are indeed very different amps.
Do keep in mind that these amps, due to age might need some maintenance; such as new caps.
