Very happy with GEMSTONES from TweekGeek.
Coincidentally I have five Shumann Resonators,
so each unit now has one stone of each flavor.
It is as if the sound is tranformed, meaning everything
positive gets a boost: lower noise floor, greater transient
speed, better placement of instruments in space, etc.
I hear no negatives.
I left the strips of five in place initially, and placed them
in my "open" circuit breaker box. Not wonderful results,
but I have a Gate in there and other things that may have
been interfering... Also struck out inside the rear of an open-cage amplifier. Near the power switch of a Synergistic Research
Powercell 12 was slightly better.
The GEMSTONES are very very small, best handled with tweezers.
I bought a roll of double-sided foam tape and cut sqaures that
were just slightly larger than the stones. This helped with seeing them
and getting the stones to stick easily, without disturbing their backing.
It really was fortunate that I thought of the SGs. It might be an
advantage to treat one kind of application rather than placing
then in different areas at the same time, which is something I have
not done. I am happy with my first complete set and likely
will not explore further.
BTW, I found that all three versions, mounted together, were much more
satisfying than just using the clear stones by themselves.
These GEMSTONES, as a complete set, are pretty impressive,
in my opinion. They truly impact the music.
