iFi Audio micro iDSD Signature

Beskrivning

Out of this world
Sporting a Space Blue finish and powered by a built-in rechargeable battery, the micro iDSD Signature is a transportable DAC/headphone amp that’s ready for anything that the universe throws at it.

Battery power means it’s ultra-clean with ultra-stable DC power and avoids the pitfalls of AC mains – dips, spike and noise-inducing RFI/EMI pollution.

And with up to 12 hours playing time, depending on the headphones and performance mode engaged, it feels like you could take it to the moon and back.

Finely tuned
Based around two Burr-Brown DAC chips in a custom ‘interleaved’ configuration, the digital engine has four pairs of differential signals – two pairs per channel. This means

* a lower noise floor
* improved channel separation
* finer musical detail and micro-dynamics

The micro iDSD Signature handles up to PCM 768, DSD 512, 2xDXD and MQA. All this is done natively. Both PCM and DSD remain ‘bit-perfect’.

Precision personified

Extensive jitter-eradication technologies are applied to the digital engine, including iFi’s GMT (Global Master Timing) femto-precision clock and the intelligent memory buffer.

The micro iDSD Signature also comes with iFi’s GTO (Gibbs Transient Optimized) digital filter installed. And exclusive firmware available on our website means you can change digital filters as you wish.

Circuit training

With up to 4100mW of power the micro iDSD Signature can drive all manner of headphones with aplomb, from highly sensitive in-ear monitors to current hungry planar headphones.

The signal path has been refined to maximise sonic texture. High spec components featuring class-leading qualities such as low ESR (Equivalent Series Resistance), high stability and low distortion mean top-notch sound quality and maximum musical enjoyment.

Add in the direct-coupled nature of the circuit – no coupling capacitor is present – and the micro iDSD Signature definitely runs rings around the competition.
