Vintage TDS-II True Dimensional Sound Active Audio EnhancerUp for sale is the rare and highly sought-after TDS-II True Dimensional Sound Audio Enhancer. This is the desirable active, non-passive model that features its own dedicated power supply circuit, delivering a noticeable boost in presence and gain that the later passive units simply couldn't match.Derived from submarine SONAR technology designed to isolate specific acoustic signatures underwater, this legendary analog processor breathes incredible life, space, and depth into any two-channel stereo system. If your current setup feels flat, compressed, or sterile, putting this unit inline is like cleaning a dirty window—the difference is night and day.Key Features & Sonic Performance:• Active (Non-Passive) Circuitry: Unlike the passive licensing variants (like the AR TDS202), this standalone unit utilizes an active signal chain to provide a clean voltage gain boost (approx. +3dB) and maximum impact.• True 3D Soundstage Expansion: Drastically opens up the front-to-back depth and height of your music without using cheesy digital delays or artificial phase-shifting tricks.• Psychoacoustic Harmonic Restoration: Restores the trailing decay of notes, brings buried micro-details to the front of the mix, and sharpens transient attacks (like cymbal strikes and acoustic plucks).• Pure Analog Signal Path: Sits perfectly inline between your source component (CD player, DAC, Tuner) and pre-amp, or right inside your tape monitor loop.Condition:• Cosmetic: Excellent used condition with minor shelf wear on the chassis. Faceplate looks great.• Functional: Fully tested and 100% operational. Passes clean audio, switches seamlessly, and the active gain stage functions perfectly.• Includes:TDS-II Unit and compatible 12V power adapter
