The Reference 20 is Audio Research's flagship line-stage preamplifier, a complete rethinking of the category developed without constraint in pursuit of absolute sonic transparency. The traditional stamped chassis is replaced with a multi-metal, layered construction that disperses resonant energy, and critical circuits are mounted on custom suspended, mass-loaded boards that isolate the signal path from mechanical influence. A comprehensively redesigned power supply with advanced regulation and next-generation film capacitors lowers noise on the regulated rails by an order of magnitude, and the single-chassis REF20 surpasses its two-chassis predecessor in every respect.
