Symphony Pro PS-1 Harmonic Resonator. Asset or snake oil?

You all probably got an email promoting the Symphony Pro PS-1 Harmonic Resonator.

I've never heard of such a device.
Anyone have experience with it or a rival product.

Pretty wild claims!

Easily a major upgrade that exceeds any cable upgrade at 1/3 the price. It adds more clarity and fullness to the sound. Definitely adds harmonic resonance.
