I cannot comment on that specific combination, but I had, until very recently, Vandersteen speakers (2Ce) driven by a Bryston amp (4B-ST) and it was a terrific pairing. I used an Audio Research SP-9 Mk.III preamp in the mix (as well as a McIntosh C-30) and really liked the results. Within the limitations of my budget and ambition, it was probably the cleanest and most articulate (in all the right ways) system I've had in here. My listening room is on the small side and I only moved away from that gear to go in the direction of tubes, a recent preference on my part.
I think you might have a nice combo there!
