Woo Audio - WA11 Topaz  (LITE PACKAGE)

PORTABLE AMP/DAC

It all started when we were developing the WA8 Eclipse. We learned that in order to reduce the size greatly, it needs to be with transistors. Introducing the WA11, an ultra-compact high-performance headphone amplifier, plus DAC. Over the course of 3-years of intensive research, we created 9 working prototypes deployed in real-world applications, before getting to the final version. The WA11 delivers an audiophile sound quality that rivals many desktop systems & with the features that users dream of.

Weighing in at only 0.9 pounds & 0.95 inches thick. It is a battery-powered, fully-balanced headphone amplifier & DAC running in a Class-A topology. The WA11 is capable of driving the most demanding full-size headphones while maintaining an ultra-low noise floor for reference IEM's. The DAC is an ESS Sabre capable of decoding PCM up to 24bit / 384kHz & up to DSD128. There is also a 4.4mm balanced input for use with balanced sources such as a modern digital audio player (DAP) or home audio source.

The future is the USB Type-C port. The amp/DAC has two of them (one for an input & one for charging (USB 2.0 compliant). Separating the two allows the user to listen to music while charging the internal battery simultaneously. This feature extends the industry-leading 7 hrs. of playtime immensely.

The performance & usage flexibility of the WA11 will change the way we enjoy music, plus open a new world for what a Hi-Fi system should be.
