Passive pre with Bryston 7B ST??


I am wondering whether the Bryston monoblocks are suitable for passive attenuators/pre while the Bryston preamps (are said) to be the weak link of this pre/power combo. As the Brystons are pretty well known I'd gues that someone would have tried it with a passive pre (FT Audio LW1 for example)

The Brystons have a high sensitivity (0,8 volt) and a high input impendance. My cd-player (Musical Fidelity Nuvista 3D) has a low impendance 2 volt output according to the red book standard.

Any comments?

Although I haven't tried any passive attenuators with my
Bryston 7Bs, I tend to agree with the majority of the peanut
gallery that an active pre-amp is the way to go. I use a
Golden Tube Audio SEP-3 tube preamp with my Brystons, and I
find the sound dynamic and extended. I think that with passive attenuators, you'll lose some of the dynamics and drive, depending on what music you listen to. I would hazard a guess that, unless the CD player was designed to drive an amplifier,( i.e. Wadia/Krell w/ digital volume control and humongous power supply and regulation) the rest of said CD player circuitry would be penalized by the output
attempting to drive an amplifier through passive attenuators. Either way, good luck in your search.
