When operated within its operational limit, the Ground Zero brings no compromise to the musical signal. Like a good doctor, we want power products to do no harm to the audio waveform. Running through a long playlist of both dynamic rock and classical music, along with a number of delicate acoustic pieces, it’s clear that neither dynamics nor tonality are affected by inserting the Ground Zero.

The Ground Zero works as promised, solves the problems it was designed to address, and is reasonably priced. Right now, Underwood HiFi is offering an intro price of $399 – even better. There’s no point in buying exotic four and five figure power conditioning products for an $800 vintage component, or a budget tube amplifier. For that, we are happy to award the Ground Zero one of our Exceptional Value Awards for 2021. If you’re having this problem, you need one.
