Can you provide some more information as to how amps and DACs improve the audio? I’m new and need help understanding. I get that these devices are supposed to do all this really neat stuff but what I really need is a detailed explanation of how each device directly improves the audio, what specific components and interactions within the devices accomplish these things and what audible measurements these changes can be seen in.

I really just want to be an informed consumer and not have any idea how the really expensive stuff I buy works. That sounds awful. Can you imagine being like that? Just throwing money at products having no clue how they work and what they do. Glad I’m not one of those guys.

Anyway, if you could go ahead and help me understand how this stuff works in like metrics and science things, I’d appreciate it so much.
