Tube Rolling for TAD-150

I will receive my TAD-150 tomorrow. I read some great reviews on this unit. Has anyone had the chance to do some tube rolling with this unit. How do the stock tubes compare with other NOS tubes?

Other components; Vandersteen 2CE sigs, McCormack DNA-1 AMP, Adcom GCD500 CD, Thorens 160 C with Goldring 1012 cartridge and LINN Basik plus arm. XTC interconnects, Signal cable and FRO-ZEN power cords....
