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.

The very low input impedance of the 14B3 (7.5K unbalanced, 5K balanced) makes it unsuitable for use with the majority of tube preamps, as well as with passive preamps such as the Lightspeed. A tube preamp that comes to mind that would have no problem driving those impedances is the Atma-Sphere MP3. A dealer presently has a new MP3 listed for sale here for $5K, without the optional built-in phono stage.

Good luck. Regards,

The primary question would be, what are you trying to improve upon in your system?  If you can elaborate on that along with the rest of your system I think you'll get much better and more helpful recommendations. 

Im actually using a 14bsst now and going to the cubed version. There is some glare in the 7k region. That according to a free spectrum analyzer app. Maybe I should wait and see if the cubed Bryston tames it. I have acoustically treated my room with curtains , panels and tube traps.. Vinyl does not have as much harshness but I am upgrading to a Marantz as-10
So, what are your source components, speakers, and cables, and are you using any power conditioning?
