The new Signature edition builds on its predecessors reputation for exceptional sound quality and versatility with enhanced circuitry in critical areas and a new 4.4mm Pentaconn headphone output, among other upgrades.\u003c\/p\u003e\n\u003cp\u003eThe new model is housed in the same 177x67x28mm extruded aluminium enclosure as the Black Label version, like all products in iFis longstanding micro range has been. But, rather than black, the micro iDSD Signature sports a Space Blue finish a new colour reserved for Signature versions of some of iFis most popular products, of which there will be more.\u003c\/p\u003e\n\u003cp\u003eAlthough powered by a built-in rechargeable battery, the micro iDSD Signature is more of a desktop-sized device than pocket-sized one a transportable DAC\/headphone amp that can easily be moved around without requiring a mains socket. Being battery-powered gives it a performance advantage over mains-powered products, too ultra-clean and stable DC power, negating the issues that can be introduced by AC mains electricity with its dips, spikes and noise-inducing RFI\/EMI pollution.\u003c\/p\u003e\n\u003cp\u003eThe battery delivers 6-12 hours of playing time, depending on the type of headphones connected and the performance mode engaged. If the battery runs low whilst in use, it can be plugged into a power source to charge and play at the same time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2 x Burr-Brown True Native® chipset\u003c\/li\u003e\n\u003cli\u003eHigh-res Audio Support with True Native® playback\u003c\/li\u003e\n\u003cli\u003eMQA Support\u003c\/li\u003e\n\u003cli\u003eCustom OV Series operational-amplifier\u003c\/li\u003e\n\u003cli\u003eiFis exclusive S-Balanced® circuit\u003c\/li\u003e\n\u003cli\u003e3D+ Holographic®\u003c\/li\u003e\n\u003cli\u003eXBass+®\u003c\/li\u003e\n\u003cli\u003eTexas Instruments low-noise ICs\u003c\/li\u003e\n\u003cli\u003ePanasonic OS-CON caps\u003c\/li\u003e\n\u003cli\u003eDirectDrive®\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFinely Tuned\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBased around two Burr-Brown DAC chips in a custom interleaved configuration, the digital engine has four pairs of differential signals  two pairs per channel.
