EHA5 adopts a new ID design, with 146dB ultra-high dynamic range and output voltage up to 700Vrms, far exceeding other electrostatic amps, so it would perform better when paired with electrostatic headphones. EHA5 supports XLR, TRS, RCA inputs and two steps of gain setting, and supports shutdown pass-through. In addition, EHA5 supports 12V Trigger input, which can be switched on and off synchronously with other devices that support this function.\u003c\/p\u003e\n\u003cp\u003eThe BIAS voltage of TOPPING EHA5 is set to standard 580V. It features real-time detection for different supply voltages internally. This protects the headphones from being damaged. 700Vrms output swing is different from the 580V bias voltage and doesn't damage electrostatic headphones. And the highest voltage won't be applied to the headphones unless the amp is pushed to do so and which in turn could damage your headphones if pushed into distortion.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eUnleash Your Electrostatic Headphones' Full Potential with EHA5\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eExperience the ultimate audio performance with the EHA5 Electrostatic Headphone Amplifier, specifically designed for electrostatic headphone owners who demand the very best from their gear. Electrostatic headphones offer unparalleled sound quality, but often their true capabilities remain untapped due to the limitations of standard amplifiers. The EHA5 outshines the competition by delivering enhanced audio details, a substantial power output, and convenient features tailored to make the most out of your listening sessions with your electrostatic headphones.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eOutstanding noise control\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe EHA5 boasts an impressive 146dB SNR, ensuring that any audible noise is eliminated. With noise levels under 35uVrms @G=L and under 80uVrms @G=H, you'll enjoy crystal-clear sound without any distractions.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eImpressive power output\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe EHA5 delivers a remarkable 700Vrms and 2000Vp-p output swing, significantly improving upon the competition.
