ERS Cloth uses

search avsforum.com for "ValhallaPC"

If you do a deeper search, you'll find that ERS cloth usage has to be used very carefully. In general, I've read that using too much ERS can actually " throw some of the baby out with the bath water". Trial and experimentation is required to fine-tune the sound where you use the product.

I've had great success in using it wrapped around speaker terminals, interconnect terminations and inside CD player right above transport. Also wrapped around powercord plugs.
This stuff definitely cuts out the digital glare and harshness from your digital components. Plus lowers the noise floor.
It is a tweek that truly works!!
