The Acoustic Signature Tango Apex NEO is a reference-level phono preamplifier—a critical component in high-end analog systems designed to extract and amplify the delicate signal from a cartridge with extreme precision.

At its core, the Tango Apex NEO is built around a strict dual-mono architecture, meaning each audio channel operates completely independently, with its own dedicated housing, power supply, and amplification stage. This design dramatically improves channel separation, reduces noise, and enhances overall clarity and soundstage realism.

What sets it apart is its fully balanced signal path and extensive adjustability. With multiple gain settings (40–70 dB), customizable impedance and capacitance loading, and both XLR and RCA connections, it can be precisely matched to virtually any MM or MC cartridge. All functions are controllable via remote, making it unusually user-friendly for such a complex piece of equipment.

The engineering goes even further with separate shunt power supplies per channel and galvanic isolation between digital control and analog circuits, ensuring ultra-low noise and signal purity. A built-in headphone amplifier and optional volume control add flexibility, allowing it to function not just as a phono stage but as a minimalist control center in a high-end system.

Weighing over 75 lbs, the Tango Apex NEO reflects Acoustic Signature’s philosophy of mass, isolation, and precision. The result is a phono stage that delivers exceptional transparency, dynamic range, and musical realism—intended for systems where nothing short of reference performance will do.
