Acoustic Signature Tango Reference MM/MC Phonopreamplifier
Frequently Bought Together
Product Overview & Specifications
The ACOUSTIC SIGNATURE Tango Reference is a flagship phono preamplifier engineered without compromise. Utilizing a single-ended Class-A circuit topology, it delivers high resolution, speed, and precise holographic imaging. Every capacitor within the Tango Reference is hand-selected and individually measured to guarantee accurate RIAA equalisation with an ultra-tight tolerance of ±0.1 dB.
Designed for complete versatility, the Tango Reference offers front-panel gain switching for MM, High-Output MC, and Low-Output MC cartridges alongside wide-ranging DIP-switch load impedance options. The internal supercharged linear power supply delivers clean, noise-free DC power and can be upgraded with external power supplies. The entire circuit is housed within a massive 18 kg CNC-milled solid aluminium and stainless steel chassis for shielding against external electromagnetic interference.
