I'm just trying to think of myself when I was a noob to all this. I remember when I first came across EQ I didn't know if it was important or not what order I put the parametric filters - answer is the order doesn't matter, you know when you input them into Peace or whatever. And with headphone amps, if they get loud enough then they're not underpowered, related to the myth that often goes round that you need a headphone amp with a lot of power to bring out the best in most headphones. Maybe an FAQ related to "how DACS sound" - as in they don't sound like anything, if they measure well then they're transparent and don't add or take away anything from the recording. Can't think of anything else off the top of my head. I mean there's a lot more to understanding audio, but in the form of simple FAQ's can't think of anymore right now.
