24 bit anything is nice stuff; I noticed a great improvement in quality when I bought a rather low cost Lexicon FX unit. Nice and clear and not boomy as many Fx units are, unless you buy the 24 bit and higher if it exists.
If it's analog, you are hearing it with your ears.
If it's digital, it is a formula of numbers that converts analog into nice sound via the digital process; when you hear it again, it's analog. It's a simple world sometimes.
