Why do I feel a debate coming on??
"I personally think it's 'mostly' BS"
at least you state it as an opinion, rather than fact........
"prices charged for shelves or little cones "
...actually big cones are far better
Just google for vibrations+lab equipment to observe that microphony is a big subject affecting science kit as well as audio equipment.
"if it makes you happy then it's right for you."
...perhpts I am being a little sensitive but doesn't this sound a little patronising?
fwiw the gains I've made experimenting with cones and iso platforms (at little cost) have indeed made me very happy.
Power of pursuasion?
No, I don't think so. YOu can loose as easily as you can gain....and you soon know which it is. When you here an instrument you know you've never heared before you are pretty sure you've gained.
IMO of course.
