iFi nano iDSD LE DAC/headphone amp

We are told ....

It’s a well-known fact that if you listen to music through headphones from a smartphone, tablet or computer, sound quality can be massively improved with the addition of a portable headphone amp. Products like the Chord Mojo have earned considerable acclaim; but for the average smartphone user, the ticket price is steep. Enter the iFi nano iDSD LE: a small, rechargeable, high-performance portable DAC/headphone amp that connects via USB and combines sophisticated audiophile circuitry with a down-to-earth price tag.
