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 and DAC. Over the course of 3-years of intensive research and 9 working prototypes deployed in real-world applications. WA11 delivers an audiophile sound quality that rivals many desktop systems and with the features users dream of.
Weighing at 413g and 24mm thick, the WA11 Topaz is a battery-powered, fully-balanced headphone amplifier and DAC running in a Class-A topology. It is capable of driving the most demanding full-size headphones while maintaining an ultra-low noise floor for reference in-ear monitors. The DAC is an ESS Sabre capable of decoding PCM up to 24-bit/384kHz and up to DSD128. There is also a 4.4mm balanced input for use with balanced sources such as a modern digital-audio-player (DAP), home CD player or DAC
The future is USB Type-C port. And WA11 Topaz has two of them - one for data, one for charging (USB 2.0 compliant). Separating the two allows the user to listen and recharge the internal battery simultaneously. This feature extends the industry leading 7 hrs. of playtime immensely.
The performance and usage flexibility of WA11 will change the way we enjoy music and opens a new world for what a Hi-Fi system should be.
