BAT VK owners: How did NOS tubes change the sound?


I have been reading in the forums about several people tube-rolling their BAT equipment. Would like a survey from everyone as to:

1. Which tube brands and NOS vintages were used?
2. What sonic improvements or changes were realized over stock tubes?

Thanks in advance for your participation.

This is in my vk60. Dynamics and detail were improved beyond belief. Best $400 bucks I ever spent. I'll post later on the exact brand and vintage. Purchased from Upscale Audio.
