David12, first off, I normally don't add to these threads after my first post. They always seem to turn ugly, and I refuse to get caught up in that. To me, proof is something that can be measured. I will admit, everything doesn't fall into that catagory. To me, I think thats rare. I have added things at home that didn't seem to make an audible difference. If you do that with 5 things, then took them all out, I think that might be audible. Some things I've seen, but not limited to, would be the likes of the "teleportation tweak", jars of pebbles, temple bells, dishes filled with water, dots on your walls, and on and on. There are just to many to list. People must buy them, so there is a market. I could tell you a certain size block of wood, sanded with a secret combination of sandpaper, and placed under my chair made my system sound better. Some fool would buy it. To me, this is nothing but "snakeoil". Do I know, or understand everything? Certainly not. It's my opinion, nothing more. I think just a bit of common sense should tell you if it even has a chance to help. For the people that buy these things, and believe, good for you. I'm just never going to be one of them. Anyone that cares to throw the insults, or testimonials, go ahead, I won't be debating it.
