Puritan Audio Labs GroundMaster CITY & RouteMaster grounding system

Terry,

I am wondering if you (or anyone else) have compared the GroundMaster City/RouteMaster to the Synergistic Research Ground Block?

The basic (non-active) SR Ground Block costs about $600, same price range as the RouteMaster.

I have the RouteMaster & GroundMaster City combo and love it. I wanted to share something I recently added to it, which has improved things even further.

It’s called the Ground Box Booster, from my friend Krissy Tetrault at Heartsound Audio. It is an unassuming, but weighty, black box with a single 5 way binding post. The contents of the box are proprietary, so I don’t have any info to share about that. It is a passive device, no power cord. You simply wire it into an available port on the RouteMaster (or other similar ground box). At some point I need to get around to trying the Puritan cable that my components are plugged in with, but, for now, I am using wire from some old TARA Labs ICs I had lying around.

Upon adding one to my system, a little more than a month ago, I I heard an increase in clarity, sense of ease, natural detail, and dynamics. Voices and instruments were simply more “real” and emotionally engaging. Shortly after, I wired in another one, these qualities increased even further, and I have been enjoying them ever since.

Disclaimer: Krissy is a friend, and I received these products in exchange for testing them.

Having said that, the Ground Box Booster has been a real game changer in my system, and I don’t anticipate it ever leaving.
