Dedicated Power Amplification from Usher’s Reference Range
Usher is a Taiwanese audio manufacturer whose range has included both loudspeakers and substantial separate amplifiers. The Reference 1.2S follows the traditional power-amplifier approach: source selection and listening level are handled upstream, leaving this unit to drive the left and right loudspeakers.
For someone assembling a separates system, that arrangement provides useful freedom. A suitable analogue preamplifier can remain in place as source components change, while a DAC or streamer with a properly implemented variable output may combine source and volume-control duties. The important consideration is matching the control stage and amplifier correctly, rather than treating a separate power amplifier as a direct substitute for every integrated model.
Choosing It for Your System
The R-1.2 family is documented as a substantial stereo design, with a published eight-ohm output rating around the 120-watt-per-channel level. That puts it in the territory of a main-system amplifier rather than a compact desktop unit.
Its size and weight also deserve consideration before installation. Plan the rack position and cable access in advance, using a sturdy supporting shelf with room around the amplifier for ventilation. This is equipment best accommodated on a properly planned hi-fi rack rather than squeezed into a small enclosed compartment.

Important Owner’s Notes
Use a suitable volume-controlled signal feed. A fixed-output CD player or DAC should not be connected directly unless an appropriate preamplifier or attenuator is in the signal path. Confirm the intended connection format before purchase if your system depends on a particular input type.
Earlier service history and capacitor replacement status are unconfirmed; no recap or rebuild is being claimed. As with other older amplifiers, future maintenance should form part of the longer-term ownership plan. Leave the heatsinks and ventilation openings clear and allow the amplifier to cool before moving it.
