iFi PRO iDSD

Pro iDSD Desktop DAC

There’s no wrong way to enjoy your music as long as you’re enjoying it, so we’ve created the Pro iDSD reference grade DAC and amp combo to be the centerpiece for whatever strikes your mood. In this upgraded version of Pro iDSD we have switched out the 2.5mm output for the 4.4mm, added a little more juice with 4,200 mw for balanced outputs and 1,575 mw for single ended, and upgraded the PBC. When convenience matters, stream from your favorite services like Spotify, Tidal, and Qobuz over WiFi for up to 24 bit / 192 kHz high resolution streaming audio. For the ultimate in hi res audio connect your PC, laptop, tablet, digital audio player, Android, or iPhone (with Apple Camera Connection Kit, not included) to the high speed USB 3.0 input for native playback of all formats, including FLAC, WAV, PCM, DSD and even MQA decoding. The micro SD TF card slot and USB A inputs let you connect your external library, and you can run a network usb drive through the built-in ethernet port. Dust off your CD collection and plug in your DVD player via the SPDIF optical toslink jack to rediscover old classics. On the back, RCA jacks and a balanced 3 pin XLR output connection work directly with your home audio amplifier or receiver allowing the Pro iDSD to function as the preamplifier for your home audio. When speaker listening isn’t an option, the built-in headphone amplifier will drive your favorite pair of headphones with ease as you listen to your favorite beats. Choose a filter from one of five options or apply DSD

ll incoming DC is converted to a high-frequency waveform then rectified and filtered by a choke input capacitor filter. This produces a first-level DC bus from which all further voltages are derived. The circuit also generates a galvanically-isolated power supply voltage for the USB input circuitry.

The digital section is powered by a bank of ‘Super Capacitors’ totaling 6.6 Farad (6,600,000uF). Individual low-noise TI LDO Regulators with local LC filtering provide the final low-noise power for all individual digital sections; a total of six individual regulators cover Clock, S/PDIF Input and the DAC’s digital section. For the analogue stage (especially the tubes) higher voltages are needed.

The whole stage effectively operates on a 60V rail offering massive potential dynamic range.

HIGH RESOLUTION AUDIO

Play any high-res file natively with the Quad Dual Core Burr-Brown DAC chipset, which means media file formats and information remains unchanged for the truest sound, from MP3 up to studio grade Bit- perfect DSD 512, DXD, PCM 768 as well as MQA (Decoder)

WiFi STREAMING

All controlled from the palm of your hand via an app, choose a wireless connection to stream your favorite tunes from Tidal, Spotify, Qobuz – the list is endless. 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

POWERFUL

Our balanced headphone amp outputs up to 4.2 Watts of power and will drive a wide range of headphones. Connections for 6.3mm (1/4″), 3.5mm TRS, and 4.4mm TRRS balanced

MUSIC YOUR WAY

Options include the ability to listen in solid-state, tube or tube+. We have also added digital filters to add flavor to your listening, such as the GTO filter, Bit Perfect, Bit Perfect+, Apodising, and Transient Aligned. Remaster any track (excluding MQA) to DSD 512 or DSD 1024. All there for you to customize you listening experience
