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

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.
