So, after much testing, for me, in my system, with the Ether Regen, I did not hear any benefit with using the Aardvark. As a matter of fact, I thought the bass was diminished. My hat’s off to the seller who allowed me to try it and then grant a refund (-) shipping costs. This seems to be the only way to tell if these types of filters will work well within a system.
Perhaps without the Ether Regen this device would have performed differently.
I sent it back.
