noble100"demonstrates you are either just making things up or have absolutely no experience....they are the least noisy of all existing amp types by a wide margin. Everyone who has ever heard class D will concede this...What exactly is your problem?
Perhaps his "problem" is that "everyone" does not agree with your opinion, assessment, or reasoning and you can insist that you are correct and try to insult others into agreeing with you and so the "problem" is in you’re refusal to properly acknowledge, accept, and reconcile with those with who you do not find yourself in complete agreement.
I've heard Class 'D' and think it's ironic that it's Class 'D' because a 'D' or an 'F' is what it deserves IMO..
