Bryston preamps

Wow.  Frankly, you've now got $11,000 amps powering $7000 (or less) speakers.  It's absolutely worth seeing how your system sounds with the new amps after they've had 100+ hours to break in, but at the very least at this point you've got to explore the possibility of upgrading your speakers.  My extensive experience with a Bryston BP6 in my system is that it will neither create, nor mask, a glare in any area.  It's a virtual straight wire with gain, and since the BP6 shares very similar topology with the BP26 (as per James Tanner) I'd have to surmise going that direction will not bandaid your situation in any way.  Once you have your new amps broken in I'd suggest following up here.  I know there was a big change from a 2BSST to a 3BSST2 I had in my system in terms of refinement and more natural sounding treble, so you may well be on the right path.  But still, I can't help thinking those amps could deserve and reward you with better speakers down the road.   Anyway, keep us posted.

very sweet system that you are putting together.I am in a similar situation w/ the Bryston cubed series (power amp and matching pre-amp). Hopefully I will get my audition in August.Also, the Marantz SA-10 catches my eyes as well.  Keep me posted on the delivery and break-in on the SA-10.
As soon as I demo the 4B3, I will update here for you.
Happy Listening!

Thanks all. Yes I might be a little anxious and not estimating the impact the 14b3 will have

I haven't heard neither the 14BSST nor the 14B3 but my brother's 7BSST monos were simply transformed when he switched from the BP25 to an ARC REF5SE. His Magnepan 3.7i speakers never sounded so good. Just one (more) data point for whatever its worth.

Hey soix. Those OHM speakers are actually closer to $20k speakers in real value.
1. You buy direct from the manufacturer bypassing the dealers.
2.The soeakers do not have to be very robust and reinforced since the sound waves travel off the cones differently.
3. There is only one driver and tweeter. They are quality ones unlike mid price speakers with multiple drivers where cheaper ones would have to be used to compete costwise. 
4.Down side is the bigger ones are power hungry and they might not be the most dynamic. They do take a while to break in.
For me they do convey the music. 
Now I just cant wait for the 14b3.
