ifi Audio Say….
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.
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.
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’.
Features:
Octa-DSD512/PCM768 and 2X DXD.
Dual-Core Native DSD/PCM Burr-Brown® chipset.
Fully balanced 4.4mm output with (4,100mW).
