I set up my crack amp to use 6SN7's from the beginning. Started by punching the front hole allowing me to install a second octal socket. From there all I had to do is make the necessary wiring changes during assembly. I really love the way it sounds. But I couldn't help wondering what the circuit sounded like with a 12AU7 up front. Basically I went the opposite way and bought an adaptor that converted the 6SN7 to a 12AU7. After some seriously critical tube rolling sessions I decided to stay with the 6SN7. Both tubes sounded really good. The 12AU7 actually did a better job at what I would call "micro detail." As good as that sounds there is a downside to having such good detail. That is to say that the 12AU7 really revealed all the nasties in poorly recorded material or poor analog to digital transfers. The 6SN7 is a lot more forgiving when listening to less than optimal source material.
Anyway, that's my 2 cents. As they say, "your mileage may vary." There are a lot of variables to consider. So have fun experimenting and set your amp up the way YOU like it.
