Tube Roll for McIntosh C2300 PreAmp


Has anyone had good luck rolling the 12AX7 tubes on this unit? I have heard the Golden Lion are good.

I hears JJ Tesla was also a good choice for tube. Anyone have experience with JJ Tesla?
I just rolled a pair of Gold Lion Super Cryo and already noticed the diff. I also got a pair of 1950 Telefunken that I will try after 100 hours with the GL. What difference could I expect from the Tele.?
