tube pre for bryston

Finally decided and bought the Bryston 14BSST. Thinking of putting a tube pre in front of it to drive my Legacy Focus mains. I will be looking used since I still need to upgrade my Pre/Pro for the video side soon. I have only read positive things hear about combing ss amps with tube pres. I heard a great combo (nameless for purposes of this conversation)and did like the sound, unfortuantely not a combo I can afford. Any comments and sugestions?
Thanks, dave
