Tube pre to use with Bryston 4BST

i am using a conrad johnson pv-11 with my 4b with great
result,any conrad johnson preamp will do an excelent job

A tube pre might do it, but check your CD player. I auditioned this player and thought it was too bright sounding.
I frankly doubt BAT's or Sonic Frontiers pre's (some of the few w/XLR connectors) would take away the edge you're hearing.
The Bryston is a neutral piece.

Have you considered trying a pair of different IC's
I have a kav 300 and use mit 330 cvt's with it and i hardly find it bright or harsh... If you get into a tube preamp, you will need to find a set of tubes as well that suits your needs sonically... I have an arc ls7 with my analog system that I have had 3 different sets of tubes in and it sounds different each time...
Try the IC's first, then look for a preamp...
Good luck,
Joe

I have a Bryston 4B-ST which I use with a Bryston SP-1 (which essentially uses the BP-25 circuitry). I found that the Bryston gear is sufficiently revealing that the interconnects are very important. I recently replaced the IC's I was using with Alpha-Core Goertz TQ2's and found they made a substantial improvement: cleaner, more extended treble that is sweeter and less "edgy"; and a bit more transparency and tonal accuracy in the mid-range.

By all means, try a tube preamp with the 4B-ST, but I would also suggest you try a pair of Goertz TQ2 interconnects -- I think you will be pleased with the improvement in your system's sound. There was a pair of 1.0 meter TQ's for sale here on A-gon last week for $110, so you might see if they are still available. If not, you can buy a new pair of TQ2's direct from Alpha-Core for $186.

I also have the 4Bst and was using a older SS preamp. I felt that I was robbing the Bryston of good upstream data and a new pre was needed; so I started searching different forums and boards both reading and posting questions about tube preamps.

Along my search I found a few people that are highly respected audiophiles. All agreed that the 6SN7 tube was the better choice in a preamp, and that the 6922 tube was good but no match for the 6SN7. They offered so many makes and models for a preamp I was overwhelmed, but one company they all gave " 2 thumbs up" was Cary. I asked about both the Blue Circle and Rogue preamps and they said their no match to a Cary and if both are Stereophile class B then how is the sterile Adcom GFP750 class A?

I found out that Dennis Had the owner of Cary, also owns Audio Electronic Supply and simply put is a champagne on a beer budget.I bought the AE-3 and this $600 preamp is fantastic with the Bryston, never in my wildest dreams would I have thought that a tube preamp could sound so great. If I had the funds on hand I would have went Cary......but Im happy for now.

You cant switch out of the XLR's or you dont want to? You might be passing up on great sounding equipment if it is that you dont want to? Just a thought.

Good luck, Kris
