Topping EHA5 Electrostatic Headphone Amplifier

Plugged in my Stax and the soundstage opened up immediately—the high-voltage bias circuit makes a massive difference I didn't expect from such a compact unit. It's dead quiet with no background hiss, and the build feels solid enough to last years.

The high-voltage bias circuit really brings out the detail in my Lambda headphones without any harshness. It runs cool even after hours of listening and the build feels solid. Exactly what I needed for my desk setup.

Finally an amp that lets my electrostats breathe without any background hiss. The high-voltage swing gives them this effortless clarity I haven't heard before. Setup was literally plug-and-play.
