Tube Matching Primer

Hi all. I'm in the process of rolling tubes for the new Cary 303/300 cd player and I am a novice in tubes. I understand from reading earlier posts that tube matching may not be critical in low power applications like cd players or preamps. However, I would still like to understand what matching is and what the numbers mean. Thanks in advance for your help.

Thanks Jay. I assume "very linear tubes" are those with a wide, even frequency response and the only way to test that is with your ears, which is what I'm doing (it's really kind of fun).

Any advice on tube matching? I read a lot about tube matching and I'm not sure how to match, what the numbers mean, what the acceptable tolerances are and so forth. Any insight and advice would be appreciated from the community.
Thanks again Jay and Dcrookham53. I hope my question wasn't too naive or vague since there were no other responses -- unfortunately, I'm a tube novice. If anyone needs more clarification to my question, please let me know.
