Tube preamp for my Bryston 7B3


Hi Goners...

  I'm currently running Bryston 7B3 Amps from a Bryston BP26 Preamp to Focal Sopra 2's.  VERY HAPPY with things but thinking of adding (not replacing my BP26) a tube preamp just for that occasional sound change we get. Has anyone experimented with different tube preamps for their Bryston 7B3?  I realize the Bryston has a low 7.5K ohm input and may be tough to find a good tube match. 

tnx...2bz

Budget?  What sound characteristics are you looking to gain and/or not lose with the tube pre?
Might look at Rogue RP series. Good value stuff. I have had the RP-1 for several years and really have enjoyed it. Put in matched Mullards from Andy at Vintage Tube Services. Match that with class A/B solid state amp and Focal 926.There is an RP-5 over on USAudiomart.

I had a listen at Octave at RMAF a couple years ago and their stuff is way impressive.

Octave also has this baby for even bigger $$ but very cool.

I'm using a Bryston 2.5 SST2 w/a Luxman CL38U SE tube preamp w/excellent results.
