Grungebuster Washers

TA Board Improvement

Replaced the hard nylon washers under each corner of my Denon DK-300 armboard with the Grungebuster washers and they do a good job of tightening the SQ. Very pleased. An inexpensive tweak that actually works.

First purchase

Great communication. Accepted a change to my order without any issue. Will certainly use again.

Worked great on components

I ordered a few different sizes of Grungebuster Washers to isolate the transformer, rectifier tube mount, and also out four of them between each rubber feet and chassis that make noticeable improvements to my DAC. They made the sound more natural, focused, clear without being clinical, no dynamic was harmed. BTW they key to make them work is not to tighten the washers too much so that they lose their suspension property.
