What's a good tube pre-amp to match Bryston 4BST

I've used both a Rogue 99 Magnum and a VTL TL 2.5 with a Bryston 4b-st. Both worked pretty fine, but, have to admit, the Rogue and the Bryston always seemed to have lingering issues and never really did get along as well as I might have liked....

Over the seven years I had Bryston amps (4bst then 7bst monos) I used a Melos Sha-Gold, a Rogue 99 Magnum and an Aestetix Calypso. All were great matches.

I also had pretty good luck with a Rogue 99 magnum with the 4B-SST I had. Even better was a Holvand HP-100. Rogue was more "tubey" sounding than the Hovland at least with the tubes I had in it which at this time escape my memory as to what they were. Many Bryston amp owners have used ARC gear with much success.

I use an ARC LS 25 into 7 B-STs and am happy and previously used an ARC LS 8 II that sounded ok with the Brystons.

I owned the 99 magnum with stock tubes. It builds like a tank with separated PS and the remote is first class. I do believe some reviewer claimed the lower 66 sounds more tubes than the 99. Eventually, I sold the 99 with 120 mono block . One bad thing abt the entry level SP16l pre is the lowest volume was set pretty loud so late night listenning may not be suitable to some folks.
