The Micro iDSD BL is the upgraded version of the award winning micro iDSD. It packs in a very compact (and portable!!!) form factor an incredible number of features which make it the Swiss Army Knife of High Quality USB D/A converters:

  • It’s an asynchronous USB DAC, with RCA outputs
  • Powered by the Dual-core Burr-Brown DSD512/PCM768/2xDXD True Native® DAC with headphone amplifier
  • It has both SPDIF optical and Coaxial inputs\outputs (so its also a SPDIF DAC or transport)
  • USB input with integrated iPurifier Technology (it reclocks audio streams, eliminates ground loops and clears USB power input noise)
  • A very good Headphone amp, capable of driving pretty much anything (and with selectable impedance match)



Why we like it:

  • It’s simply the most flexible USB DAC there is. It can be used in a huge variety of ways, and it excels in all of them!
  • It’s the best headphone amp I’ve ever had, coupled with a great sounding DAC!
  • Analog Volume control: the good old charming volume knob!
  • Adjustable output level and impedance make it suitable for every Headphone
  • It plays Native OctaDSD (DSD512) and all the DSD gamut


Made for DSD

The Micro iDSD BL plays up to True Native Octa-DSD512/PCM768/Double DXD. With its special Dual-Core Burr-Brown native DSD/PCM chipset at the heart, the micro iDSD is capable of True Native PCM768, Octa-Speed DSD512 and 2x DXD. It plays simply everything.


A killer headphone Amp

Its 8v/4000mW output makes it one of the most powerful headamps to drive even the most hungry of headphones with ease. Its Perfect-Match means it can be fine-tuned to any headgear from IEMs all the way through to large headphones, by matching their impedance with the integrated selector.

The micro iDSD has 3 different power modes Eco, Normal and Turbo. Capable of 4000mW, 1000mW or 250mW, the micro iDSD is able to drive the full gamut of headphone and amplifiers alike. With iEMatch there to dial to suit any IEM, the micro iDSD has redefined the headphone amplifier class.

Used along with the analogue volume control, the diminutive size of the micro iDSD belies its uncanny ability to drive virtually anything and everything!

And it’s portable and battery powered!

The micro iDSD integrates a 4800mAH battery, allowing it to be powered by the cleanest possible power source and to work also if your Pc\Smartphone\Tablet is not able to provide enough current for it.

Also, it works like a power Bank if you need it! SmartPower® is the micro iDSD’s onboard recharging feature for Smartdevices. Its 4800mAH battery is able to fully recharge an iPhone two-times. Compatible with Apple and Android, phones and tablets, it is another example of iFi’s commitment to customer needs – enjoy high-end audio on the go without worrying about the phone going flat.
