Best 12AU7 Tubes for BHK Preamp?

@erastof  PS audio has forums on their website where tube rolling is discussed.  If you're not familiar with that site, here are a couple links:

Thank you for the recommendations! 

For me the best current 12AU7 tube is Psvane 12AU7. I have tried TungSol, Mullard, Gold Lion but nothing compares to Psvane.

New to tubes, this was interesting. Just ordered GE 1289, but i kind of feel i should order another setup to. I just wonder what?

The following link will bring up a plethora of facts and opinions; regarding the various iterations of and replacements for the 12AU7.           I've found this tube monger, one of the most honest, dependable and knowledgeable, in my experience:   http://www.audiotubes.com/12au7.htm   

I have a BHK preamp and my favorite is the Amperex 7316 made in the Heerlen factory in the Netherlands. They can be labelled for other companies too. I recently bought some with the Mullard label. If you’re familiar with the Phillip’s etched codes, the 7316’s tube type is Ct.

To my ear, this tube just adds a sweetness to the music that just makes me want to listen more.

The 7316 is a variant of the 12AU7 that, from all that I’ve read, is compatible with the 12AU7.  I've never had a problem subbing it for a 12AU7.

Unfortunately, they are expensive and, having just checked ebay, people are selling some pretty shoddy tubes at NOS prices. But you may want to keep your eye open for a nice pair at a reasonable price.
