Just wondering what the figures for tests on tubes represent, and what are good figures?

Below I have two examples of testing figures for matched pair tubes. Which are the better performing tubes, and why?

1. Tested : 13.5/11.8-12.4/11.2 7LC delta 0C1

13.1/11.4-12.5/11.4 7LG delta OC1

2. Tested : 9.8/9.8-9.5/9.5 7xx delta9A2

Hello folks,

I was wondering what steps you normally take in order to check monitor systems, detect their weaknesses, the balance, balance, etc? For instance, what CDs do you bring, and what specifically are you listening for?

Alecio-

Would you explain to me how you use dithering? I think I understand what it does, but in my daily setup I find no use for it. What do you use it for and are there benefits I am not seeing because I don't understand it? Please feel free to get very in-depth with this if you like, I am perpetual student of all things and do not shy from learning something new.
