Tried with Audeze LCD-1 and Sennheiser HD 6xx. I only had Woo Audio WA7 gen3 and Hegel H95 to compare with side by side. Aune has darker background than WA7 and is a touch more dynamic and a bit more resolving. There is greater separation of instruments and the soundstage is deeper (again, a bit). Considering the price, this is an amazing accomplishment. Hegel H95 throws a wider sound stage, but I'm not sure if it's more accurate. Overall, very pleased with the unit. I normally don't buy lower priced units, but this is the only portable class A unit I could find under 1k. This unit holds its own against much higher priced desktop amps.
