Bryston preamps

Marantz 8005 sacd player. PS audio P1000 power regenerator powering everything but the amp. OHM 5000 speakers with Canare 4s11 speaker wire. Pangaea and PS audio power cords and Pangea SE interconnects. Analog set up is a fully upgraded AS final tool TT with Graham 2.2 forearm and an Ortofon 2m Black cartridge and an Acoustech ph1 p phone preamp. I have the speaker cables 2 feet off the floor. All components isolated with cones or damping material. Dedicated AC line

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.
