The EAR534 has been designed to meet a wide variety of needs, from the most demanding of audiophiles to the professional seeking high-quality monitoring equipment in the studio field. The circuit design uses push-pull output and driver stages, a high-quality in-house designed output transformer, and low negative feedback. It is capable of operating in bridged-mono mode, to make a true monoblock amplifier. Tube life is long (and replacement costs are modest) and the circuit operates in pure Class A.
