Hi Steve,
Thank You once again for your fast shipment.
Thank You for such wonderful and cost effective products. They all worked well in my system.
The Cone/Spike grounding bass brings further improvements. Clarity, darker background, sound staging.
The preamp ultrasonic tube dampers are just FANTASTIC. I'm using them on my cd player as well as my hybrid amp.
I started putting 1 damper in the cd player. The improvements are instant. WOW!!! :thumb:Everything is cleaned up nicely. Basically, as what you've described in your products' capability, they did all you've said. it's as if a thick curtain has been unveiled and the music just flows as it is.
Next, I put 2 other dampers into my hybrid amp. And again, they did wonder!!! All the muddy, blurry, congested sounds (NOT music) are gone. Now I'm listening to music.

I've yet to fine tune the dampers position to (maybe) optimize the potential further . But I'm already very happy with what they've done.
For those using tube gears, do yourself a favor by trying these dampers. Highly recommended.
My setup is sitting on less than ideal condition. I do not have proper solid racks. Speakers are on raised wooden floor. All the vibrations are interfering each other (all audio components). Your products have helped me a lot. THANK YOU.
I'm a skeptic but now I'm totally convinced of your products. I will be looking at ordering more of your products to further treat other chains of vibrations.
Lastly, IMHO, your products do their job at tackling vibrations and they do not introduce any sound signature while doing their job. They're neutral. That's very commendable.
Cheers,
Gary
