The EAR 509 100 Watt mono is a Tim de Paravicini design classic that has been in continual production for over 30 years. Its timeless rectilinear form is hand finished in polished chrome giving a clean and elegant look.

The EAR 509 have been built with reliability at its heart, backed up by three decades of servicing experience for the product. Changing valves is intuitive with the EAR 509’s self- biasing. Accurately set the operational biasing by adjusting two sets of dials. With four LEDs, it informs you that it’s set with equal intensity, allowing you to easily adjust the biasing when necessary. EAR Yoshino’s transformers sing with just about anything. Tim de Paravicini bespoke designed both output and power transformers with music in mind. EAR hand-build them locally and then rigorously test them to ensure they meet our exacting standards. They engineered the EAR 509s to take full advantage of this quality while maintaining the 100 watt output.

From one the best audio designers the world has known, the EAR 509’s have become legendary. And for good reason. They’re a solid workhorse with power and musicality that makes them so enjoyable to listen too. There’s a rightness to their sound that others struggle to achieve. A smoothness, and wonderful flow of energy that keeps you locked into the music. These have balance input. RCA input available on order at slightly lower price.
