Not necessarily. There are an infinite number of positive numbers, but -13 will never be one of them. Ergo, even with infinite possibilities, you still may not see a particular combination (even if it does fit the criteria; my metaphor is imperfect).

In theory, yes. I’ve never actually plugged it into a computer. It’s a Sony PS-LX300USB. Looks like you can pick one up used for less than $100. Might be worth it if you’re currently buying everything twice.

My record player has a USB port…
