I didn't say anything about your accomplishments, only that I care not for putting my stuff in front of other people to have them tell me their opinion. A judge is a critic to me, paid for their opinion. People may follow that critic as they may share their opinions. Audio is very subjective, I might keep an opinion or suggestion in mind when making a purchase but ultimately I'd like to listen/experience for myself before I do.
Exactly. Not only is your home the easiest place to create a system with great fidelity, it's also the cheapest and most rewarding. I'm not going to spend over a thousand bucks on a car's system when it can be stolen, smashed or victim to some tragedy. One could argue a house is subject to the similar things, yet I'd counter home insurance is cheaper and tragedy less likely.
