What are the best drop in subs for a 12AU7??

I am considering a Minimax preamp, but understand that they sound best with rolled 12AU7s. I have some Mullards which I would try first but have heard that there are even better choices of slightly different tubes. What are they and are they difficult to find? Thanks any help is appreciated.

Amperex 7316 and Telefunken ECC802S are the top 12AU7 tubes you can find.

I had 4 Amperex 7316s sold them on ebay few years ago since I don't need 12AU7 for my application. It shouldn't be hard to find but do expect to pay $100 a pair.
Because of lower noise floor, everything sounds better in every aspects of the regular Holland made Amperex 12AU7 with less forwardness.
