40+ watts SET, cost is not a problem
Phasemation MA-5000  
Small factor phono stage
Check out the Lejonklou Slipsik/Entity (mm/mc), very "tube like" sound, hard to beat for the price.  
Aric Audio
doodlebum, I use to run a pair of Zu DW, worked surprisingly well. I have since moved on to a pair of Lii Song origin s10, match made in heaven.

I can only join the choir singing praises for Aric. Happy owner of Super 2A3 SET for little more than 3 years now. I have yet to consider looking anywhere else for another amp. Feed it from a passive Slagle autoformer preamp, audio bliss.
