Tube suggestions for hybrid integrated amp


I've had the stock tubes (12AU7) in my Rogue Sphinx for a few years now and I'm ready to upgrade.  Right now I'm leaning toward  Tungsram ECC82 but I am open to suggestions.  I'd prefer to buy within the US as I'd prefer delivery in the next ten days or so.
Speakers are old Dynaudio Contour 1.3 MkII.  The room is lively but not overly bright or ringy.  I listen to a lot of classical chamber music, combo jazz and (mostly classic) rock. 
Any suggestions appreciated.

I have been using Gold Lion 12AU7's sourced from Ron Sheldon at Cryoset.  Very linear sound and they last a vey long time!  I buy all of my tubes there if Ron carries what I need.  My Gold Lion GZ34 rectifier tube from Cryoset is a huge improvement over the stock Sovtek tube my gear came with.

I've read many accolades for Andy at Vintage Tube Services as well.
