If I recall, the M200s have torroidal power transformers, so magnetic flux leakage from them should be low.
If your AV stand is made out of steel (at least the shelves), they will act as shielding.
I would also consider moving the 950 up to the shelf that the vcr is presently on and then placing the M200s on the shelf that the 950 has now vacated. The 950 will now be in a somewhat more accessible location and the AC line cords to the M200s and speaker leads do not have to go by the 950. Yada ...yada...yada...
