Replacing Vincent SA 31MK any experience?

I have a Vincent SA 31 MK pre amp and SP 331 MK power amp. I am considering a new pre amp and favour an all valve rather than hybrid.  Obvious choice appears to be Vincent SA T7, any experience of this set up or different pre amp. 


Buy a used pre with that cash.   You can buy often something that retailed for  double.   I bought a demo Zesto Leto and it was the best money I have spent on audio in a long time.  Totally elevated my system to next level.  It literally sounded like a speaker upgrade, it was that pronounced of a difference.   The preamp is the heart of a system,  some patience and luck could really pay off.
