A new exponent of the effort made in recent years by the legendary American firm Audio Research to create tube amplifiers that not only redefine what is possible in the field of musical reproduction, but also do so based on an aesthetic incredibly beautiful.
Externally, the Reference 80S shares the same dimensions as the exquisite Reference 160M monophonic unit. Regarding the technical specifications, they are the same as those of the aforementioned Reference 160S, including an exclusive automatic polarization circuit that indicates the age of the valves and, in addition, the oscillations of the supply voltage.
Likewise, the user can select between Triode and Pentode operating modes (with output power of 2x70 W RMS and 2x33 W RMS respectively) to accommodate listening to their speakers and personal preferences.
Like the Reference range amplifiers that precede it, the Reference 80S uses a fully balanced differential topology because, according to Audio Research , it provides the highest performance (including a frequency response curve ideal for the demanding demands of the best digital “Hi-Res”) and the least possible distortion.
In short, an extraordinarily musical and truly exclusive electronic that is completed with entirely manual manufacturing in Maple Grove, Minnesota ( EE.UU. ).
