David Berning preamp..looking for suggestions

I am on a look out for a good tube preamp with preferably a reference grade phono stage inbuilt. I am moving from a tube amplification to solid state amplification primarily to feed my Tannoy Prestige with all the power it needs. In the process I dont want to end up in an all SS system which will be too much of a deviation. So I would love to have at least a tube preamp and if possible a tube phono too. I know it may ultimately involve using a SUT but I can take that much of a compromise (if at all). 

I am considering the Berning ZOTL-One preamp with in-built phono stage. There are many reviews of his power amp but not much about his preamp. Has anyone heard his preamp, any impressions (even second hand) would be very helpful.
