High-quality amplification circuits
The WM8740 Wolfson DAC samples PCM audio up to 192 kHz/24 bit and the LME49860 operational amp delivers outstanding signal & performance with ultra-low distortion, low noise & high slew rate. A high-bandwidth TPA6120 headphone amp minimizes noise, delivering more than 120 dB of dynamic range to ensure music is heard with every detail.
An internal, asynchronous USB 2.0 clock supports the highly accurate conversion of digital signals to analog sound. This precision clock signal generator also reduces timing inaccuracies when converting digital signals into analog waveforms. The result is superior audio performance with minimal noise and distortion.
Built to last.
A compact aluminum enclosure protects the delicate internal circuitry from outside interference and impacts while alloy bumpers protect the volume knob from external impact.
Flexible headphone support.
A two position, side mounted gain switch allows you to optimize amplifier output level to match varying headphone impedances ranging from 8 to 600 Ohm. Select between Low or High settings to maximize your listening experience.
