IFI nano iDSD Black Label DAC /Headphone Amp

Description

Amazing portable IFI headphone amp/dac in excellent condition with all accessories and factory packing materials.
This precise, analogue volume control
is normally found on items at a much higher price point. Its transparent sonic nature delivers a smooth sound with no loss in music retrieval. It delivers the sonic goods.
Zero Jitter
® equals good audio. Is it essential to have a
very precisely buffered digital signal before it goes to a DAC.
We pushed the envelope even further by doing this not only with the
nano iDSD BL
‘s USB input, but the rest of the digital interfaces as well.
This unit has up to 10 hours of non-stop playing time. Always make sure you switch it on first and then plug in your device.
The Burr-Brown True Native® chipset means file formats remain unchanged or ‘bit-perfect’. This means you are listening to music as the artist intended in the format in which it was recorded.
At iFi we use Burr Brown extensively in our products having selected it for its natural-sounding ‘musicality’ and True Native architecture. Our experience with this IC means we know how to make the most of it.
Listen to Master Quality Authenticated audio straight out of the box. Connect to Tidal Masters and check the option to stream MQA.
MQA is an award-winning audio technology that enables music fans to stream the original master recording into their home, car or on their mobile. In the words of Gilbert O’Sullivan, iconic Irish-born singer-songwriter, “The great thing about MQA is that it delivers the finesse that was there in the desk sound. It’s tremendous, it sounds really good.”
