bryston bp-26 VS cambridge 840e

hi i have a bryston bp-26 preamp im using with my bryston 4bsst amp.would i be going backward by getting a cambridge 840e got great reviews,can anyone advise,,ris
Likely. The BP26 costs twice as much, though much of that is relatively expensive labor and a 20 year warranty. I'd say Bryston's circuit design and QA is top notch. They've been refining their preamp design for decades. The BP26 has a separate power supply which could lead to quieter operation. There's also the possible synergy with the Bryston amp.

If there's a feature the 840e has that the BP26 doesn't and you need it, then that's another issue. I think the Cambridge 840 series of components offer amazing value and time may show that they are quite reliable as well.

The only negative comment I have about the BP26 is a lack of a HT pass through.
What are you looking for that you think the BP-26 is not providing?

I've had the BP-6 in my system, which is identical to the BP-26 minus the balanced connections and separate power supply, and I found very little if anything to fault. I would think you'd have to go much further up the price chain to get substantial improvements, but if you demo the Cambridge I'd be curious to hear what you find.
having owned a variety of Bryston products over the years and a BP-26/14BSST combo (the preamp on loan) I can attest to the synergy between their preamps & amps. Never having listened to the Cambridge its not really fair of me to say you are moving backwards but if the BP-26 is too "neutral" for you (which BTW its designed to be) then maybe you are looking for a "different" type of presentation?

I agree that if you want to stay with solid state and don't want to change your amp there are other choices out there and not necessarily better ones. You might want to consider a tube preamp if you are looking to warm (some people say color) things up a bit?

If reviews mean something to you you should review all the great reviews on the Bryston website
I have seen a diagram of a Bryston pre amp with XLR inputs. Funny thing is, the pre amp is not of a balanced design. I don't know if they changed that. But I always feel kind of cheated when an amp or CD player has balanced in and outputs but the design is just a standard design and the use an IC to convert XLR to RCA.
Mordante, if you are talking about this schematic:
you are mistaken about the BP26 not having differential inputs. You should not feel cheated at all.

The opamp symbol labeled DOA33 at the upper left of the diagram is Bryston's discrete implementation of an opamp and in this instance implements a differential input. It is this device that provides the common mode noise rejection. It is true that the rest of the circuit is single-ended (no harm in this). The pair of DOA33 discrete opamps at the upper right implement the phase inversion for the balanced output.

Bryston has a long history of poo-pooing the use of IC opamps. That's one of their selling points -- even in their CD players and DACs.
