iFi - iDSD Nano LE HD USB DAC
The nano iDSD Light Edition (LE) is newest entry-level DAC from iFi audio. The iDSD LE has the same DNA as the multi-award winning nano iDSD but without the SPDIF output, digital filter selection and runs on DSD128/PCM384. This ‘pocket rocket’ comes in at the entry level with a pedigree that offers the same sonic performance as its sibling. Its scares the living daylights out of other entry level DACs and many other more expensive DACs too.
The nano iDSD LE is able to play True Native® meaning there is no conversion; PCM stays PCM and DSD stays DSD. This means no signal loss as it ensures the music file is ‘Bit-Perfect.’ This is important because it ensures the highest sound quality as there is no loss from file conversion.
The nano iDSD LE supports Hi-Resolution formats up to 384kHz and DSD128.
At iFi, we care little for ‘which format is best.’ Rather, we are obsessed with replaying each format at their optimum.
What does this mean? Selection of the most advanced chipset and exemplary implementation.
The Burr-Brown DAC chip used was developed by BB Japan and BB themselves (as opposed to BB/TI). Though the product introduction was post-merger, this chipset represents Burr-Brown’s “swan song” for the best of their converter technology and remains to this day, held in very high-regard.
The latest advancements in Smart Devices such as iPhone/iPad/Android has transformed them from a mobile phone to a portable, high-end Computer Audio Source*. These Smart Devices are able to natively encode and transmit high-res PCM/DSD/DXD audio. As the iDSD LE is able to natively decode the same, this high-end ‘Transport+DAC’ combination offers astounding sonics yet is all just palm-sized for great tunes on the move as well as at home.
Below are some screenshots taken with iPhone with Onkyo HF Player > Camera Connection Kit > iDSD LE. As you can see, each high-resolution format is being replayed, even DSD.
There are clock crystals and there are the clock crystals in the iDSD LE. The ‘clocks’ used in the iDSD LE which have been supplied by AMR, are military-grade temperature compensated master clock modules which avoid the creation of unwanted beat frequencies. Such crystals reduce overall digital noise and push jitter to the vanishing point. These clocks have been specifically-sourced from the telecommunications industry where standards are far more exacting than those in the industrial sector (which normally supplies to the audio industry).
Just like other products in the range, the iDSD LE benefits from AMR trickle-down technology to lock out jitter, the iDSD LE does not settle for Asynchronous USB transfer alone. To truly cancel jitter, it also employs AMR’s Zero Jitter® Lite technology from the famous AMR DP-777 which has Asynchronous as the starting, not finishing point.
The iDSD LE very visibly features a built-in precision analogue volume control which is more than a match for anything found at twice, even thrice its price point. Its smooth action reflects its smooth sound. It sure delivers the sonic goods.
This fastidious attention to detail and consideration for the user is standard for iFi.
A key factor behind why the nano iDSD LE sounds so ‘true’ is DirectDrive® which means there are no output coupling capacitors. This ‘direct signal’ path is without peer and is a mainstay of the iFi DAC range including the iDSD LE. The sonic transparency is there for all to hear and is second-to-none.

iFi - nano iDSD LE HD USB DAC
This is a high value product which allows one to radically improve sound quality with minimal investment of space, pretense or resources. I should imagine that only hard-core audiophiles or owners of very inefficient headphones would not be very pleased with either the purchase or result.
