The EAR534 is a top quality EL34 power amplifier, designed by Tim de Paravacini to retain the strengths of traditional EL34 circuits whilst delivering excellent drive capability and detail retrieval. This is what the EAR website says ...
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 mono block amplifier. Tube life is long (and replacement costs are modest) and the circuit operates in pure Class A.
