Bryston 14 B SST with Martin Logan SL3 speakers?

Thanks for your suggestions, your comments are what I'm looking for to force me to have an open mind about this next important upgrade. I live in Nova Scotia, tring out a wide variety of new gear at home is nearly impossible so I have to rely on other means of evaluating equipment (quess work) which means that I will purchase it used and try it into my system. The Pass Labs gear has always looked to me as very fine gear, The X250 certainly is a beautiful looking piece of gear, one that wouldn't be a problem to stare at sitting between my speakers every day.
Keeping in mind of future upgrades in speakers, ones that may handle much more or less power than my SL3's, would you still suggest the Pass Labs X250 or should I look at the X350 for it's higher power capabilities? What is the sound like with these amps, at low listening levels?
I would appreciate your comments on this.
Thanks

Thanks for all your sugestions and comments folks on the amplifier recommendations. At the end of the day, I'd really like to have an amp that would do justice to most types of music through most types of high end speakers but I think that may be asking just a little bit too much don't you think?
