A somewhat obvious thought (to me at least) is that the dealer should be willing to demo identical systems with and without Stillpoints to give prospective purchasers a chance to hear any differences without having to take them home first. I understand that each of us might not get the same results with our own systems as the ones in the store but if you don't hear any differences between the two (or three or more if application variations are possible) whilst there, you likely won't at your home either....
Stillpoints - snake oil?
Anybody here using Stillpoints Ultras? My dealer thinks highly of them, but I am very suspicious.
