Sound Quality That Rivals Desktop System
It all started when Woo Audio was developing the WA8 Eclipse. Woo designers learned that in order to reduce the size greatly, the circuitry needed to use transistors. Introducing the WA11 Topaz, an ultra-compact, high-performance, solid-state headphone amplifier and DAC. It was developed over the course of three years of intensive research with nine working prototypes deployed in real-world applications. The WA11 Topaz delivers an audiophile sound quality that rivals many desktop systems and includes the features users dream of having.
The performance, capability, and flexibility of the WA11 Topaz will change the way you enjoy music and change the definition of what a hi-fi system should be.
Fully Balanced Headphone Amp Design
Weighing one pound and measuring one inch 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.
For superb sound quality, the Topaz uses a premium TKD four-channel balanced potentiometer. The headphone outputs consist of a 4.4mm Pentaconn balanced jack and a 1/4" TRS unbalanced jack for use with full-size headphones. User selectable HI or LO power level output ensures compatibility with the widest range of 'phones.
Powerful DSD-Capable ESS Sabre DAC
The DAC is an ESS Sabre ES9018M 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 of USB connections is the USB Type-C port. And WA11 Topaz has two of them - one for data, one for charging, and the ports are USB 2.0 compatible. The separate charging and data connections allow you to listen to music while simultaneously recharging the internal battery. This feature extends the industry leading figure of seven hours of playtime immensely.
The XMOS xCORE-AUDIO asynchronous clocking USB is compatible with PC, Mac, Android, and iOS devices (with Apple CCK or Android OTG adapter).
