Product Description

iFi Audio Pro iDSD DAC, Headphone Amplifier and Streamer is for those who like music in all its flavours, especially high spec. With the option to listen in solid-state, tube or tube+, there’s something for everyone.

We also sell the  Signature version of this model.

DSD1024 and more

The Pro iDSD plays all files from MP3 up to hi-res DSD and MQA. For the first time, it brings Studio Grade DSD1024 to a wider audience – a rare feat. You are well and truly future-proofed. All controlled from the palm of your hand via an app.

GTO Muscle

As with most iFi gear, the engineers added filters to add personality to your listening. Just like the American muscle car, it adds gravitas and a new dimension to your listening experience. iFi offer Bit Perfect, Bit Perfect+, Apodising and Transient Aligned filters.

Music your way

Choose a wireless connection to stream your favourite tunes from Tidal, Spotify, Napster. Take it up a notch by using a wired Ethernet connection to play from a router or NAS (Network Attached Storage). Or relax with AirPlay to enjoy playback from your iPhone, iPad or Mac.

USB Connectivity

Use USB Type A to connect a hard disk drive or a memory stick or Type B to connect a laptop or server. Or slot in a micro SDHC card with music files for instant playback. Enjoy soulful tunes from your CD transport and enhance your gaming or movie experience as you connect via the coaxial/digital input.

The USB input section has its own separate power management system with multiple regulators and filtering operating from the galvanically-isolated voltage generated to power this section.

Moved by music

Finally, iFi have given you a choice of headphone sockets and outputs to cover all tastes.

Whatever your mood, however you connect or listen, the Pro iDSD has an option for you. With LINKPLAY WiFi/network playback, built-in Spotify and Tidal and wide protocol support for 32-Bit/192kHz and DSD64, the Pro iDSD can be also used without a computer to stream audio directly.


iFi Pro iDSD has a ‘quad stack’ of Bit-Perfect DSD and DXD DACs by Burr-Brown. The ‘interleaved’ configuration means up to 8 pairs of differential signals can be used and mixed, equal to 4 pairs of signals per channel. The Pro iDSD employs the new XMOS XU216 X-Core 200 Series 16-Core processor. All-digital processing is Bit-Perfect unless certain filters are selected. Upsampling to DSD1024 has previously only been available to a select few.

The Pro iDSD makes it available to a wider audience. The DSD1024 remastering is handled by the Crysopeia FPGA. Data is sent to the Memory Buffer from all inputs. Here it is de-jittered to eliminate any transmission of source jitter to the DAC output. The data from the Memory Buffer is further re-clocked by the low-jitter Global Master Timing clock which also drives the X-Core 200 and FPGA.

Galvanic isolation

All inputs are galvanically-isolated (including USB). Unlike other amplifiers that have the same circuit and just switch in/out the tube section, the Pro iDSD is the very first of its kind to have two individual input circuits – one tube (General Electric 5670 tubes) and one solid-state. This results in the ‘best sonics of both worlds’.

The amplifier audio circuit is fully discrete, fully-balanced with either tube or J-FET input switchable, bipolar second stage and MOSFET-buffered bipolar Class A Power stage. The Pro iDSD is packed full of premium components – a Japan Alps rotary volume potentiometer, audio-grade ELNA Silmic capacitors and a bank of Elna Dynacaps ‘super capacitors’.
