What seperates "hi-fi" from "mid-fi" in cdp's?


I find that in my search for the right CDP I really don't know what, mechanically, seperates the good from the not-so-good. Although I understand which brands are more highly regarded than others, I don't understand why.
Along those lines, I would also really appreciate a very brief description of the primary working parts of the cdp and how they differ among "levels". For instance, how does the number of bits matter? Or is it just another useless audio stat?
Or, if I am asking a bigger question that I think I am, maybe you could direct me to a good reference for this issue? Thanks JB3

Straight listening helps, IMHO, only if one has an experience in that - one should know what to listen to, and what nuances to pay attention on...
I don't think there are characteristics that would clearly distinguish mid-fi from hi-fi... Too many manufacturers claim such things as "oversized power supply", but only some of them really benefit form it from sound quality perspective. Price doesn't mean anything eiher. I think the only way to evaluate a component is a combination of gathering info about unit's design advantages along with looking for opinions, and with listening.
