Full Technical Explanation

Lush is a subjective listening term used to describe an audio presentation that feels rich, warm, and full-bodied. It often implies slightly elevated lower mids and a gentle high-frequency roll-off, giving the sound a smooth, flowing quality. Lush sound is generally perceived as musically pleasing rather than strictly accurate, and it contrasts with analytical or sterile presentations. It is commonly attributed to equipment like tube amplifiers, vinyl systems, or speakers with voiced warmth and wide harmonic content. While not always neutral, lush sound is often sought after for its emotional appeal and long-term listening comfort.
