Preamp upgrade for Bryston 3B-SST Power Amplifier


I am looking to upgrade my preamp.

My current Setup:

Cambridge Audio 840C CD Player
VTL 2.5 Tube Preamplifier
Bryston 3B-SST Power Amplifier

Kindly suggest a good upgrade to my existing preamp, that is a good match to the Bryston 3B-SST Power Amplifier.

Are there any advantages of upgrading to a preamplifier with Balanced Inputs?

Tubed preamps that I have owned with Bryston amps (4B-ST, 4b-SST & 14B-SST) - Rogue Audio Magnum 99, Hovland HP-100, Lamm L2 Deluxe (very nice) and now have an ARC LS-26. All were good matches with my amps. Unfortunately I have not had any VTL preamps so I cannot advise as to what may be different from those I have listed above. I will say that the ARC is the least "tubey" sounding off the units I have owned. Dollar for dollar a used Lamm L2 Deluxe is hard to beat...

They say that the 3B-SST is not a true balanced design so using single ended cables over a shorter distance may be just as good. That being said I have found that my ARC sounds best (IMHO) running balanced so I use all XLR cables/connections in all my gear (even my 14B-SST).

If you are not averse to SS preamps don't discount Bryston's own BP-26 - there is a definite synergy between it and their amps although maybe you are just a "tube" kind of guy...

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?
