Stillpoints - snake oil?


Anybody here using Stillpoints Ultras? My dealer thinks highly of them, but I am very suspicious.

I know some do...when I purchased my first Classe amp, the manual recommended an upgrade power cord...
they do know what they are doing, but they also have to sell and do business...and they can't alienate their dealers by recommending products and brands the dealer doesn't carry...
fortunately most of these products can be tried either free or for minimal cost and decide yourself after listening in your own system...
Who said anything about recommending particular brands? I said generic. If the dealers providers of  amps, transports, TT etc.. convey to the dealer hey such and such cord or interconnect , isolation device works great with our product I am sure the dealer would be more than happy to sell them in his store . This is simple marketing 101 to create relationships,  assuming of course the manufacturer believes these added devices actually  work.  Here a simple example,   say the maker of my amp, micromega advises their dealers that for example  Audioquest products work great with our amps then unless the dealer is a moron they are going to tell potental buyers, you know micromega recommends AQ products with their amps and will for sure start carring AQ if they don't already. Nothing I keep reading here makes any sense from a marketing standpoint on thus reluctance of manufacturers recommending products that their suppliers and dealers could also sell IF THEY WORK. Now if they DON'T think they make a difference then I can see the downside of recommending something. Good lord GE not only recommended Finish dishwashing detergent with my new dishwaher they gave me free samples with it.  I guess with the knowledge they were going to alienate loyal Cascade users. 
Either way, the OP is working with a dealer, and should get a free trial , then easy to decide
