I had 3.6R's for years, and liked the match with Bryston very much (although I must say the Sanders Magtech was by far the best amp I ever used with Maggies, followed closely by the Cary MB500's) and when I first got those together I had a Bryston preamp.
I eventually switched to a Cary SLP98p F1, that was the hot rodded version sold through Upscale Audio. I still have the preamp, and now that I'm in a smaller room, I've traded my 3.6R's for a super MMG system (with a Bryston 4BSST2 btw).
I love the sound of Cary preamps, it's decidedly warm, and that balances, to my ear, the sound of high powered planar speakers with matching amplification.
The SLP 05 or SLP98 models will work very well for you.
I've also always loved the ARC preamps, but they are not as warm as the Cary's.
Good luck, cheers.
