Never had any Zoethecus racks in my home, but I do own the Sistrum rack. To my ears it is a revelation, and it is beautiful to boot. Improvements are simply dramatic, ie you dont need "golden ears" to hear any differences. Soundstage grows wider and deeper while image specificity improves. Treble extends further, and with a life-like decay, bass tightens, and vocals become unveiled. All of this while keeping the pace and timing of the music intact. Highly recommended.
