Product Highlights
This unit was recently serviced at Jeff Rowland Design Group in July 2025. A relay was replaced on the CD input and upgrades were verified. Per Jeff Rowland, this unit has: "all upgrades and updates, including total silver teflon wiring"
"The Rowland stood out well ahead of the others -- the sense of "space" and "air" was almost palpable with the Rowland, and its ability to resolve a soundstage was breathtaking. The Coherence One has an enormously natural presentation -- there is no grain, no noticeable artifacts, and the performers seem to be alive."
