I'm fairly new to this hobby but I would suggest trying a good quality tube pre-amp that would mate well with your bryston. I tried this and found that it took some glare and brightness off without diminishing the controlled bass that I was used to. You could also try a tubed cdp like the Jolida and see if that takes away some of the digital brightness (and still have a grand left to experiment with some tubes and upgrade the cord on it).
Just some thoughts, as I've moved into tubes recently.
