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.

I too own and use a Bryston preamp (among many in my collection). It is the .5 from '88 (go ahead and laugh!). Still working and sounding fine indeed! I also own several tube preamps. But feel no compelling urge to switch from the Bryston .5! 
Stick with Bryston for choices in preamps. They are indeed fine sounding units! Stop being so neurotic! Enjoy what you have! Search for better recordings!
By the way, in one of my current systems I use the .5 with the Bryston 3B amp (1988). Go ahead and laugh! Still working and sounding fine! No compelling urge to change to another amp (in that particular system)!
Big difference going to new cubed series. Also new preamp i.e. an improvement. Had great luck mating 14b Sat with tubes audio note pre. 
@blueranger -- my apologies.  I've never heard a bad word about Ohm speakers and unfortunately haven't heard them myself.  I'm sure they punch way above their price from everything I've read.  Shame on me.  No way to move up in the Ohm line?

Having owned and greatly admired my Bryston BP6 and had it hooked up to a couple different Bryston amps and others, once you get your new amp burned in I'd still try to audition a good tubed pre just to see what it does.  Definitely keep in mind Al's warning about the 14B3 low input impedance though, and I think the Atmasphere pre would be an awesome pre to audition if you can.  I think a Bryston amp properly mated with a tubed pre could be a sublime combo.  Anyway, I'd be very interested to hear your impressions of the new versus older Bryston amp.
