Mcintosh c2300 preamp tube question

Anybody has tried different tubes for this preamp?
What are your experiences?

Any other changes that can be done with the preamp?

I am using JAN Phillips Black Sable 5751s now after a week with Tung Sol 12ax7a tubes. I like the Tungs better. Cant wait for the vintage (early 1960's) RCAs to arrive! All of the above improved sound greatly over stock Mac 12ax7a. BTW: the amps are 501s.
