Grand Prix versus Stillpoints

Theaudiotweak, I have been engaged in controlling resonances since the days of marble suspended on slit racketballs and Mode Squad TipToes. Most of these efforts amounted to spring with a resonant frequency somewhere. I have made comparisons of many such devices and chosen the better of the two tested, but always with most modest gain.

At one point I got a Halcyonic active device with no resonant frequency and thought it was quite good but very expensive. I could never afford more than two of these. The first StillPoints Rack with all components on it was far better than two Halcyonics and with the other components on Mana stands.

I think that the Ultras far surpass any prior device I have tried. They greatly reduce vertical vibrations. I also very much like the SR MIGs but have no idea why these cups should be effective.

One last point i want to make is that total isolation is not even desirable as there would not be a conduit for the vibrations generated inside and outside each units case to dissipate quickly. The ultras through contacting the units rid the vibrations as friction and heat. Obviously this cannot be done in total isolation as the ultras must contact unit in order to remove harmful vibrations. I just as Tbg have found the ultras to far surpass any prior device in improving the sound of my system. In fact, i was not happy with my new system until the ultras were applied.To explain why i am so sure, later this week when time allows i will write about my Odyssey of spending a 100k+ on my new system and not being happy and in fact left pining for my previous stereo until ultras were put in.Marc

Not too many audiophiles want to spend money on a Stillpoints rack.

But it is the only component in my stereo still left from 2016

(besides an Oyaide R0 outlet).

I am always amazed at how much it improves the performance of a component.

I still use the acrylic shelves, since I can fit multiple components onto one shelf (versus the grid where you can only place 1 component on each shelf).

I would probably never listen to music without the rack.
