About the ADE-24

The Margules Audio ADE-24.1 Analog Digital Enhancer is a signal processing accessory that works on low-voltage RCA analog outputs from digital audio sources. It uses digital signal processing (DSP) to manipulate harmonic distortion, adding harmonic peaks similar to those produced by triode tube amplifiers. The device does not eliminate harmonics from the source but rather adds significant amounts of second and third-order harmonics to the incoming signal. According to users and reviewers, it enhances the listening experience by making instruments sound more alive and present, widening the soundstage, and improving overall musicality without compromising audio quality or resolution. It is particularly recommended for use with mid-range digital sources such as iPods, iPhones, iPads, and standard CD players, though the designer notes it was not intended for use with very high-end DACs costing $3000-$4000 or more.
