If you’re more concerned with quality than size, there are two comparable new headphone amps. The Acro CA1000T is a second-generation “carriable” model that employs ESS’ latest high-end ES9039MPRO dual DAC and a triple amp system that allows you to choose between dual hoover tubes, conventional amping, and a hybrid that blends the two technologies. It will be available alongside the HC3, but at $2,299, it will only be available to wealthy audiophiles.
