Berning EA-230 Dual Mono Stereo Tube Amplifier
Best tube amplifier for audiophiles seeking neutral sound and electrostatic speaker compatibility.
The Berning EA-230 is a unique 30-watt-per-channel push-pull tube amplifier known for its exceptional performance and cult following. Designed by David Berning, it deviates from conventional tube amp design, utilizing 6JN6 sweep tubes originally intended for TV sets. This unconventional choice, combined with a low idle current, significantly extends tube life. The amplifier features a uniquely engineered output transformer and is praised for its near-perfect neutrality, making it an excellent choice for driving electrostatic speakers like Quads and Rogers LS-3/5A. It offers a compelling alternative to traditional tube or solid-state amplifiers.

Know before you buy
David Berning selected these tubes because they are highly durable and allow for a very low idle current of approximately 3mA per tube. This design choice significantly extends the lifespan of the tubes compared to conventional audio-grade alternatives.
The EA-230 is exceptionally well-regarded for driving electrostatic speakers, such as Quads. Its unique output transformer design and near-perfect neutrality provide the control and transparency these speakers require to perform at their best.
The dual mono architecture ensures that the left and right channels are powered independently. This separation minimizes crosstalk and improves stereo imaging, resulting in a more precise and expansive soundstage.
Yes, the amplifier supports 4, 8, or 16-ohm loads. These settings are configured via internal straps, allowing you to optimize the power delivery for your specific speaker impedance.
This unit has been professionally serviced, including the replacement of two electrolytic capacitors and one resistor. It also features a fresh set of NOS (New Old Stock) RCA 6JN6 output tubes to ensure reliable operation.
Unlike many tube amplifiers that add significant warmth or coloration, the EA-230 is prized for its near-perfect neutrality. It offers the musicality of a tube design while maintaining the clarity and detail often associated with high-end solid-state equipment.
