Thoughts on SS bass. Tube mid and high tube pre

Hi all. 

I am considering Bi amping my system. 

Current system is;
Audio Note M6 Phono pre amp 
Audio Note P4 mono blocks
Audio Note 3.1 dac
Tannoy. MG 12'S with split Xover
Heil air motion tweeters on top

I have a Bryston 4b pro on hand that I thought I might run the low end off of and run the mids and highs off the P4's. 
My Tannoy cross overs are split 

Your thoughts, cautions are appreciated.
