TAD 150 preamp tube rolling?

Just wondering if anyone has rolled any other tubes in this preamp, and if so what was the outcome? I have 12AX7's 12AT7's & 12AU7's but haven't tried any yet.

I put the same question out there twice and only the last time did I have any responses and to my knowledge, no one has found any better sounding tubes than the ones that came with the unit. Maybe your post will trigger some different responses. By the way how do you like the TAD-150 and what is the rest of your system...

Paul thinks that the frozen tubes that come with it are the way to go. Trust him.
