Other Notes: "The amplifier is probably the best entry-level amplifier I’ve ever encountered. There is enough power to drive almost any headphones. The 4-steps gain adjustments make this amplifier usable for anything from sensitive IEMs to low sensitivity or high impedance full size headphones. It has a pleasing sound signature that’s easy to like, and a simple opamp swap instantly boost the sound quality." - Headfonia
