iFi Audio ZEN Signature

Yes, the ZEN Signature Set is compatible with a wide range of headphones. While it includes a specialized ActivEQ curve specifically tuned for the Sennheiser HD 6XX, the amplifier's adjustable gain settings and balanced output make it a versatile driver for many other high-impedance and sensitive models.

XSpace is an analog processing mode designed to widen the soundstage. It helps correct the 'in-head' feeling often associated with headphone listening, creating a more spacious, speaker-like presentation without distorting the original recording.

Yes, it includes preamp functionality. You can connect the RCA outputs to a pair of powered speakers or a power amplifier, allowing you to control the volume directly from the ZEN Signature Set.

Start with the lowest gain setting (0dB) and increase it only if you cannot achieve your desired listening volume. Using the lowest effective gain setting helps maintain the best signal-to-noise ratio and prevents unwanted distortion.

Yes, the DAC component features full MQA decoding. This allows you to play high-resolution MQA files from streaming services like Tidal at their full quality without needing additional software decoding.

Balanced output provides a cleaner signal path by reducing interference and crosstalk between channels, which can result in better channel separation and a lower noise floor. While single-ended connections work perfectly well, balanced is generally preferred if your headphones have a compatible cable.
