Equitech with digital only?

It's a balanced Power System. Google equitech and balanced power.

Like all power conditioners, it lowers the noise floor. You hear a blacker and quieter background. With noise, you don't realize the amount until it's removed.

I had a EquiTech 2Q and it's the best active conditioner I had in my system. The digital, analog switched and unswitched outlets all sound different. I use digital for DAC and unswitched analog for my amps and pre. If I ever go back to active, probably get the EquiTech wall unit to avoid the switch.

All conditioners sound different removing different amount of noise so you need to demo in your system and determine if it's right for you. My brother has 2 2Q in his system and loves them.
