Designed to extract every nuance embedded in analogue grooves, the Tango Reference employs a single-ended Class A circuit topology that delivers rapid transient response, expansive three-dimensional imaging, and low harmonic distortion. All equalization capacitors are hand-selected and matched to achieve precise RIAA curve accuracy within ±0.1 dB.\u003c\/p\u003e\n\u003cp\u003eHoused in a 18 kg chassis machined from a solid block of aluminum and stainless steel to shield sensitive low-level signals from external electromagnetic and mechanical interference, the Tango Reference provides comprehensive cartridge loading options. Front-panel controls allow instant switching between Moving Magnet (MM), Moving Coil High Output (MCH), and Moving Coil Low Output (MCL) gain settings, backed by extensive DIP-switch micro-adjustments for input resistance and capacitance. Internal power is supplied by an ultra-clean, linear power supply, which can be further upgraded via an external power supply input to isolate the circuit from mains grid noise.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES \u0026amp; PROPRIETARY TECHNOLOGIES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle-Ended Class A Circuit Topology:\u003c\/strong\u003e Delivers pure signal linearity, fast transient speed, and exceptional spatial imaging without crossover distortion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision-Matched RIAA Equalization:\u003c\/strong\u003e Utilizes hand-measured, tight-tolerance capacitors to achieve an exact RIAA curve accuracy of ±0.1 dB.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront-Panel Selectable Gain \u0026amp; Cartridge Modes:\u003c\/strong\u003e Offers three distinct gain stages—42 dB (MM), 54 dB (MC High), and 66 dB (MC Low)—to perfectly match any MM or MC cartridge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtensive DIP-Switch Impedance Loading:\u003c\/strong\u003e Wide array of selectable input resistance settings ranging from 10 Ohms to 47k Ohms for precise cartridge load tuning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-Dense Anti-Resonant Chassis:\u003c\/strong\u003e Precision-milled from a solid block of high-grade aluminum and stainless steel, forming an 18 kg shield against EMI\/RFI and mechanical resonances.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuper-Charged Linear Power Supply:\u003c\/strong\u003e Internal ultra-low-noise DC supply architecture, featuring dedicated input connectivity for external upgraded power supply expansion.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch1\u003eSPECIFICATIONS\u003c\/h1\u003e\n\u003ctable style=\"width: 100%;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Category\u003c\/td\u003e\n\u003ctd\u003eFlagship Class A Phono Preamplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand \/ Manufacturer\u003c\/td\u003e\n\u003ctd\u003eAcoustic Signature\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel Designation\u003c\/td\u003e\n\u003ctd\u003eTango Reference\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircuit Topology\u003c\/td\u003e\n\u003ctd\u003eSingle-Ended Class A Circuitry\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported Cartridge Types\u003c\/td\u003e\n\u003ctd\u003eMoving Magnet (MM), Moving Coil High-Output (MCH), Moving Coil Low-Output (MCL)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAmplification Gain (@ 1 kHz)\u003c\/td\u003e\n\u003ctd\u003eMM: 42 dB | MC High: 54 dB | MC Low: 66 dB (Switchable on Front Panel)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRIAA Equalization Accuracy\u003c\/td\u003e\n\u003ctd\u003e±0.1 dB (Hand-Matched Capacitors)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance Loading Options\u003c\/td\u003e\n\u003ctd\u003e10 Ω, 55 Ω, 100 Ω, 196 Ω, 370 Ω, 465 Ω, 634 Ω, 979 Ω, 1734 Ω, and 47 kΩ (DIP-Switch Adjustable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Separation\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 92 dB (@ 1 kHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Outputs\u003c\/td\u003e\n\u003ctd\u003eUnbalanced Stereo RCA Pair\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply Architecture\u003c\/td\u003e\n\u003ctd\u003eInternal Linear PSU (24V DC Operating Voltage) | Upgradable via External PSU Input Connection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChassis Construction \u0026amp; Materials\u003c\/td\u003e\n\u003ctd\u003eCNC Monoblock Solid Aluminum \u0026amp; Stainless Steel Anti-Resonant Shielding Housing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (W x D x H)\u003c\/td\u003e\n\u003ctd\u003e435 x 244 x 85 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Weight\u003c\/td\u003e\n\u003ctd\u003e18.0 kg (39.7 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Warranty\u003c\/td\u003e\n\u003ctd\u003e2 Years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Acoustic Signature","offers":[{"title":"Default Title","offer_id":53800750481674,"sku":"USED-ASIG-TANG-REF-SIL-P","price":3490.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0917\/3283\/6618\/files\/acoustic-signature-tango-reference-mm-mc-phonopreamplifier-51888-p.png?v=1790179038","url":"https:\/\/audioemotion.co.uk\/products\/acoustic-signature-tango-reference-mm-mc-phonopreamplifier","provider":"Audio Emotion Limited","version":"1.0","type":"link"}
