Variac Myth-busting: 6ca7 at 90 and 120vac A/B You Decide

So I wanted to do an A/B test for you all regarding the effect of a Variac on a Plexi Marshall as it applies to the VH1 sound using real NOS Sylvania 6ca7 power tubes. Two series of tests are provided, a and b . Please vote below in the comments as to which is which and which you like better. I will post the answers here on Friday.
