I am using the new Mullard long plates and new GEC Gold Lions (from what I have read, the consensus is that these are the most highly regarded new production KT88's and some say they are *better* than the originals) in an Audio Note Kit 2 and have no complaints. Both are good tubes. There is no *best* tube as they are all circuit dependent. I have not tried the new Tung Sol 6SN7 but it is certainy a different tube from the EH.
I have been around tubes for a long time and there is a lot of *marketing* hype in the world of NOS too. I am just happy to see good sounding affordable new production tubes.
