iFi Audio iDefender+

This product did help but it didn’t completely take the problem away. I’m happy with this purchase and I would recommend it to help with a ground loop problem. I just have more than this can take care but because there is a difference that can be heard I’m pleased.

Before using this product, my computer caused my speakers to produce extremely loud frequencies. After setting up the product, the blend of frequencies is reduced to one or two very loud, high pitch frequencies. Reached out to manufacturer IT support 10 days ago and no response
