A review of the Grandioso D1X SE has been published on Secrets of Home Theater and High Fidelity, one of the oldest online Hi-Fi information sites in the U.S.

「There is a particular kind of audio component that seems to belong as much to the laboratory as to the listening room, and the Esoteric D1X SE is among the purest examples I have encountered.」

「In sum, the Grandioso D1X SE turns in an intermodulation result that is not merely good, but genuinely state of the art」

「Some components are admired for how they measure and forgiven for how they sound; others are loved for how they sound and excused for how they measure. The Esoteric Grandioso D1X SE refuses the trade entirely.」

「That convergence, the heard and the measured arriving at the same verdict, is what makes this a landmark converter and not merely an excellent one.」

「...how does it sound? Warm in the best sense, that lovely second-harmonic-predominant character, which is so prized by so many, with edge transients rendered in full detail yet without a hint of harshness, smooth as a silk tie on prom night.」

「If you have the means and the system to reveal what it does, the Esoteric Grandioso D1X SE is as close to a settled question as digital audio currently offers.」
