Roy Gregory has posted a review of the Harmonic Resolution Systems RXR ($6495) and R-Shelf ($1395) at The Audio Beat. His conclusions:
“The RXR frame might not be the whole story, but the fact that it has been at the center of my system for as long as it has is a story itself. In a very real sense it’s the core element that brings all the strands together, a product that makes a virtue of doing nothing — quietly. Like they say in Hollywood, Never underestimate the strong, silent type.”
