I agree with what they guy says as to me, the difference btw a noob and an experienced guy is that a noob does not know how to explain what he hears and also what is wrong.
E.g. they wont know to say the tweeter is sharp but may say damn noisy lar ur tweeter
They may say doesnt sound good lar when they mean it lacks naturalness.
They may say missing something when your tweeters aren't that airy...
