In seeking a "better" version of musical truth from their systems, there are some who are willing to try and/or buy items and/or different set-ups. There are those that, for whatever reason, seem threatened by the very existence of said items/set-ups and insist that the person reporting their experiences of what they heard cannot possibly be correct.
The majority of the naysayers haven't tried what the reporter/poster has, nor do they have a comparable system in a comparable room or, more importantly, don't have the reporter/poster's exact hearing and audio experience. To claim that the very act of trying something (paid for or not) different automatically makes the observations invalid due to bias is ludicrous. Even if you are a professional reviewer who doesn't have to pay there are still expectations, but expectations are not always bias.
So we are left with a process where a person tries a tweak, new piece of equipment, etc and in trying to share their experience and maybe even validate it a little, gets jumped on as somehow lying, being an unqualified observer etc. It is at this point where a differing opinion becomes an attack that the line is crossed, and that's where a moderator should feel free to silence the antagonist for the good of the forum.
Ridiculous assertions that someone is being ripped off or conned
How many times has this scenario played out here? Someone purchases product X, and tries it in their system. They report positive results, that it works as advertised, that they got their money’s worth, that they are happy with the purchase. Then someone, usually having zero experience with the product, replies with something like: “No, you’ve got it all wrong! You’re being ripped off! You’re being conned!
Does anyone else understand how ridiculous and absurd these kinds of assertions are?! The consumer who actually put up their own money and took the time to evaluate the product in their own home/system reports it works as advertised, they are happy with it, that they got their money’s worth. Then someone else claims they were ripped off?!
Imagine an agency investigating consumer fraud getting a complaint like this: “My neighbor is being ripped off!” “No, no, he thinks it’s great, does everything he expected it to. He’s very happy with it, but I just know he’s being conned!” Do you seriously think they’re going to open any kind of investigation into it?
You can disagree with what someone says about the effectiveness of a product all you want, but to say they have been defrauded, when they report the exact opposite, is patently ridiculous.
