@audiopoint Excellent post. Ive been involved in pro and consumer for 40+ years. Stand demos are the most shocking demos in the business. Cheap stands add a sound to the speaker that cannot be removed. A good speaker can be ruined by a crap stand. Even a good looking one.
I really wonder how many people are convinced all these accessories (stands, cabling) are all just evidence of "the man" trying to rip people off. Funny, if you do an audio demo, it's hard NOT to hear a difference. In a proper mastering room you will find a very high mass stand and weight tuned springs to completely decouple the speaker from the floor.
Here's an interesting mastering room tour of speakers mounted in glass (high mass), isolated with weight tuned springs. https://www.youtube.com/watch?v=ZAO9WjsFcaI (full disclosure, we are the supplier of ATC to Northward Acoustics and understand why he does what he does)
