Evolving from the micro iDSD series, this model combines a dual-core Burr-Brown digital engine with a high-output headphone stage delivering up to 4100mW of power. Being battery-powered allows it to supply clean DC power free from mains noise and voltage fluctuations, offering 6 to 12 hours of playback time depending on headphone load and power mode.\u003c\/p\u003e\n\n\u003cp\u003eThe digital section features two Burr-Brown DAC chips configured in a custom interleaved layout to reduce the noise floor and improve channel separation. Signal processing is managed by iFi's Global Master Timing (GMT) femtosecond clock and a Gibbs Transient Optimised (GTO) digital filter, with native playback support for PCM up to 768kHz, DSD512, double-speed DXD, and full MQA decoding. The analogue output stage utilises iFi's direct-coupled S-Balanced circuit architecture on both its 6.3mm and 4.4mm Pentaconn headphone jacks, cutting crosstalk and distortion across balanced and single-ended headphones alike.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES \u0026amp;
