±0.005 PPM (±5 ppb – Parts Per Billion) stability Emerald OCXO

State-of-the-art ±0.005 PPM (±5 PPB – Parts Per Billion) stability Emerald OCXO (oven controlled oscillator) delivers the most stable timing in the presence of environmental stressors such as airflow, temperature perturbation, vibration, shock, and electromagnetic interference (EMI).

2X lower noise

Equipped with the latest linear voltage regulators, the USB Card XE EVO delivers an astonishingly low noise level of 0.46 µV RMS. This is nearly half the noise level of the already impressive LT3045 regulators used in the previous model (USB XE), ensuring an ultra-clean power supply for your USB DAC and instant improvement in sound quality.

EMI Filter

The USB port on the USB Card XE EVO includes an advanced EMI noise reduction filter. This feature significantly reduces electromagnetic interference, resulting in clearer, more accurate audio signals and enhanced overall sound quality.

optimized firmware

The USB Card XE EVO comes with the latest firmware specifically optimized for superior sound quality. Power management features are switched off to ensure that every bit of processing power is dedicated to delivering the best possible audio performance.

External PSU option

External PSU option eliminates computer as the source of power for lowest noise & best sound quality (requirements for the PSU: 5V/1.5A min). Our OPTIMO power supplies are highly recommended for absolute best sound quality.
