The R-1.5 amplifier is designed to drive any loudspeaker, producing warm, "tube like" sound quality. It has been constructed with premium parts, including metal film resistors and film capacitors, reinforcing Usher's reputation for high-quality manufacturing. High-power bipolar transistors, designed by Motorola, can handle sophisticated power and current requirements. And its massive AC power transformer works with a high-capacitive filtering system for the purest sound. Other features include Burrow-Brown OPA2134P Sound Plus Series op amps, bridging switch for mono block operation, terminals that accept both banana plugs and spades, optional balanced inputs and large handles on the front and rear panel.
