Preamp upgrade for Bryston 3B-SST Power Amplifier

Thank you, Rgd and Bob. I am looking for a preamp with very low noise floor. I have read that Bryston preamps have a very low noise floor.

I see a lot of Bryston BP25 on Audiogon at about half the price of Bryston BP26. Is BP26 significantly better than BP25?

I would think that if a low noise floor is a key desire than a Bryston preamp would suit the bill. If you can live with a little tube "noise" (assuming that your VTL has a wee bit of it) then other tubed preamps could be as quiet as what you have now. But I have had a BP-26 in my system on loan and its dead quiet compared to the tube preamps I have had.

Now I understand the design of the BP-26 is virtually the same as the BP-25. The largest difference is the new power supply that comes with the BP-26. Now the nice thing is this new power supply can be bought separately so if you were to score a really cheap BP-25 you could get the new PS and be ready to rock. If it were me I'd probably wait on a used BP-26 (make sure the seller has the bill of sale for the new warranty regulations). My 2nd choice would be to get a used BP-25 to see if I liked it. If not then I'd re-sell it for probably for very close to what I paid for it. If I did like it then I'd either wait on a reasonably priced BP-26 and sell the BP-25 or keep the BP-25 & pony up for the new PS.

Thank you. I am currently using 1m Nordost Blue Heaven interconnects. How sensitive is Bryston BP-26 to the interconnect cables (RCA / XLR)? Do you have any suggestions on interconnects?

I think all gear has some level of sensitivity to cables. You can do a search here and over at Audiocircle under the Bryston chat board for more info. That being said if you do get a Bryston preamp try the blue heaven cables on the single ended connections. If you like what you hear then try and acquire a used set of blue heaven balanced cables. If you don't then try something new. Buy used to reduce your costs. I had good luck with Cardas Golden Refs at the time. A buddy uses Tara Labs (forget the model) between his Bryston pre & amp. Lots of good choices out there but its been my experience that copper based cables have been better choices when using Bryston components although you may find otherwise.
