The AS Resonators package consists of Basic (copper), Gold and 2 Silvers, all are new.
The Resonators work in any room in any system. simple to move and reposition.
What they do is amazing- They are small (unlike ugly and cumbersome tube traps) and are tuned to the listeners position resulting in soundstage focus, width and depth, bass clarity, treble extension…
Normally, I’m skeptical, but an A/B comparison at CES and at home confirmed that these precious metal bowls are indeed the real thing.
If you’re through with spending tons of money on ICs, amps and preamps, consider the AS resonators.
Original packaging and manual included.
