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’.
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.
