It was a one off attempt to design and manufacture a unique lateral bearing vibration control device. I was given two sets of three (6x) to test on my audio components. They should be able to handle most light to mid weight components, ie: source, preamplifier, amplifier, speaker, power conditioner, etc.
I tried them at my Pioneer UDP-LX500 4K BLU RAY player.
I did notice the soundtrack of the movies played sounded cleaner with tighter low bass, clearer mid and slightly airier high.
As for picture quality, I could have sweared a slight darker black and clearer outline at images. The colors were slightly more layered.
Unfortunately, they have decided to stop producing the device…fortunately, I got to enjoy the six pieces here.
