Anyone have any cartridge recommendations for a Brinkmann Bardo?

I just got a lovely new Brinkmann Bardo with their 10" arm along with a 
HRS isolation base made for it.  I put in the Lyra Delos cartridge that was in my old 'table and it sounds pretty great.....but I suspect I may want to upgrade both the stock power supply and the Delos as soon as my bank account recovers.  
Any suggestions?  Like everyone is telling me "get the tubed power supply asap!!"
