Bryston preamps


Bryston is renowned for their amps obviously. I have a BP 25 into a 14b3 but have a chance to upgrade now to a BP 26 or 17. Should I instead invest in a tube preamp (5k budget) or stick with bryston for synergy. Audio Advisor has Parasound and Vincent. A forum post I read about the Para sound said it might sound to lean With the bryston. I'm looking to buy new this time around. Thanks for any input. Huh there is the George Lightspeed to ponder.

When I went from the BP 25 to the BP 17 I had more bass and the background wasn't noisey.
Is anyone having issues with the BP 17_3 with hiss ? I went to audition one and heard a louder then normal hiss from the left speaker. I might go for the BP 26 instead.
I have a Luxman CL38U-SE tube preamp hooked up to a Bryston 2.5 SST2 amp and a pair of Aerial 5T's. Excellent combination.
I own a lot of old Bryston gear purchased around 2010. Just ordered a new BP-26 and new MPS-2 for a second system. The BP casing was warped and rocked when set on a table, and the MPS-2 had parts rattling around inside, plus a visible scratch. I’ve noticed quality slipping in a few brands and never thought Bryston would follow suite but it’s hard to look past such obvious oversights. Be careful. They may be so focused on cost cutting that quality is just a fancy word now. 
The Bryston preamps are ok, but if you want to improve the overall sound you should consider an Audible Illusions tube preamp, like the L1. An excellent preamp  and known to be a very good preamp to use with solid state amps without too many connectivity issues!
