The Big Ego+ is an audiophile quality stereo USB DAC which will enable you get the best sound quality possible from your CD quality and high resolution digital audio files and streaming content. The Big Ego+ supports PCM files and streams at sample rates up to 32/384k, and includes a built-in high quality headphone amplifier, separate line level analog and Toslink optical outputs, three user selectable oversampling filters, and a switchable headphone blend mode. The Big Ego+ offers the features of our popular original Big Ego DAC, but we've refined the internal circuitry to sound even better, and upgraded to a new case finish that is both more attractive and more durable.

Simply connect the Big Ego+ to any current Apple or Windows computer and it will appear as an external sound card or DAC to your favorite audio player program. The Big Ego+ is powered by the USB connection, and requires no external power source, which makes it especially convenient for driving high quality headphones from a laptop or portable computer. It will also work with most modern smart phones and tablets that utilize USB-C connectors with the included USB-C connection cable (does not work natively with Apple Lightning connector). The Big Ego+ utilizes an asynchronous USB Audio Class 2 connection to deliver the best possible performance with modern high resolution content, but it also includes a UAC1 compatibility option which enables it to play audio from many older devices at sample rates up to 24/96k.
