Excellent sounding and extremely well made power cord. This cord has received great customer feedback and professional reviews. Sablon Audio has incorporated noise and vibration reducing treatments, along with their winding structure to produce a full bodied, very clear sounding product. I find best results are achieved when this cord goes directly into a component. Extra special results with subwoofers and tubed equipment. I have a Quantum Gran Corona, and by comparison there is little difference. The Gran Corona may sound slightly more defined in the bass, the Quantum Gran Corona slightly more full in the midrange. These results varied for different components, but not by much.
