This three-in-one component can be used as a standalone unit in your setup, a DAC/preamp, a network streamer, and a headphone amplifier—the choice is yours! As a wireless hi-res network player or central DAC in your high-end setup, enjoying your favorite music has never been easier. A balanced headphone section means high-end headphones can also be directly connected to it so you can enjoy an intimate, immersive hi-fi listening experience with your favorite pair of cans. Enjoy an incredibly transparent, detailed, and dynamic sound that can resolve fine details and convey the subtlest nuances in your music. Whether you're a professional audio engineer, a dedicated audiophile, or simply someone who appreciates the finest in sound reproduction, the Pro iDSD Signature is an investment that will undoubtedly elevate your listening experience to new heights.
Dragon Cable Recommendation: We recommend pairing the iFi Audio Pro iDSD Signature with the Silver Dragon Interconnect Cable with XLR and RCA connectors for pairing other digital audio devices. Sold in pairs, our interconnect cables are designed as a neutrality solution meant to disappear between the components in your system. The Silver Dragon Network Cable will provide the most stable and reliable Ethernet connection when using the Pro iDSD Signature as a network player. Lastly, our Silver Dragon Coax Digital Cable with RCA connectors can be used for digital transmission, providing a more cohesive sound with a very fast attack and tight bass.

A Signature step up
The Pro iDSD Signature takes the original Pro iDSD and pushes it even further towards perfection. The Pro iDSD Signature has: features even more ultra-audiophile components for maximum performance. Enjoy a sonically darker background with a punchier bass and use the new included aluminum remote control to adjust settings and operate the device without ever leaving your seat. Upgraded power supply components like the top-of-the-range iPower Elite power supply lower the overall system noise by 300%. The Pro iDSD Signature also has added support for USB 1.0 and precisely matched NOS GE5670s tubes.
Power cleans. Absolute.
The Pro iDSD Signature ships with iFi's flagship iPower Elite. Coupled with the re-crafted power supply board which offers up to 300x lower noise, the music is buttery smooth. Within and without – iFi left no stone unturned in iFi's quest for the cleanest, purest, power for the Pro iDSD Signature (same for Pro iCAN Signature too!)
Designed to Amaze
The iFi Pro iDSD Signature is adorned with inputs and outputs making it one of the most advanced and versatile DACs on the market. On the front of the Pro iDSD Signature, you'll find an OLED display, input selector, digital filter selection, output selection mode, 3.5mm single-ended headphone output, 6.3mm headphone output, balanced 4.4mm headphone output, an analog volume control, and an infrared remote receiver. All digital inputs on the Pro iDSD Signature are galvanically isolated. The USB input is self-powered and doesn't draw power from the USB bus and the S/PDIF inputs use technology from the GMT (Global Master Timing) clocking system to reduce jitter.
The rear panel sports the following analog outputs: XLR balanced, single-ended signal output, and output selector that lets you change the signal output to different levels for home or studio use. You'll also find the following digital inputs: Ethernet, source host USB Type A, USB Type B, coaxial/digital input, micro SDHC, AES/EBU, Wi-Fi antenna, and BNC digital input. There is also a clock sync output, DC loop-out supply, DC power supply input, and clock sync mode adjuster.
Stacked. With tech.
The Pro iDSD Signature uses a quad-stack DAC design of iFi's bit-perfect DSD & DXD DAC by Burr-Brown in a custom configuration. A total of eight pairs (four for each channel) of differential signals are used and mixed. The powerful XMOS XU216 X-Core 200 series chipset enables the Pro iDSD Signature to provide state-of-the-art audio support- from MP3, 32-bit/768kHz PCM, DSD512, 2xDXD, and full MQA decoding. The Pro iDSD Signature also features a Crysopeia FPGA Digital Engine chip that enables advanced digital filtering and upsampling options, further enhancing the audio quality. It can upconvert PCM and DSD files to DSD512 and DSD1024. And all controlled from an app in the palm of your hand.
E-tailoring
The Pro iDSD Signature, like its predecessor, takes sonic tailoring to the extreme. The iFi Pro iDSD Signature is a one-of-a-kind product that is able to switch between three output selection modes: Solid-State, Tube, and Tube+. It is fully-discrete, fully-balanced with either tube or J-FET input switchable, bipolar second stage, and mosfet-buered bipolar Class A power stage (with Class AB for low impedance headphones and very high levels).
- Solid State: A purely solid-state J-FET based circuit of fully-discrete Class A topology
- Tube: The J-FET circuitry is switched to the valve Class A section based on 2 x GE5670
- Tube+: Reduces available negative feedback to a minimum. As a result, a greater amount of the tubes natural harmonic distortion is produced.
iFi's Crysopeia FPGA Digital Engine strikes again as it enables the Pro iDSD Signature to offer several digital filtering options.The GTO filter adds gravitas and a new dimension, and while the Bit Perfect, Bit Perfect+, Apodising and Transient Aligned filters give you even more choices to tweak the sound. The discrete, fully balanced Class A amplifier stage offers adjustable gain.
- Bit-Perfect: No digital fitlering is applied
- Bit-Perfect+: No digital filtering is applied, SINC roll-off is corrected
- Gibbs Transient Optimized: Minimum filtering, no pre-ringing, minimum post ringing
- Apodising: Modest filtering, no pre-ringing, modest post-ringing
- Transient Aligned: Max filtering, max pre-ringing, maximum post-ringing
Choose How You Listen
Bursting at the seams with opportunity, there is no limit to how you can use the iFi Pro iDSD Signature DAC & Headphone Amp Streamer. Stream wirelessly from hi-res music streaming services like Tidal, Spotify, Napster, QQ Music, and more. Use Apple AirPlay to enjoy playback from your iPhone, iPad, or Mac, or go wired via an ethernet connection to play from a router or NAS (Network Attached Storage). Playback from smartphones, tablets, and Windows/Linux computers can be achieved using the DLNA network audio playback. Audiophiles with a large digital music collection can access it by connecting to a hard drive (HHD) or pop in a USB memory stick or SDHC card.
With a variety of headphone outputs—single-ended 6.3mm, S-balanced 3.5mm, and balanced 4.4mm—you never have to choose which pair of cans you want to use. You can easily switch between In-Ear Monitors (IEMs), wired headphones, or power-hungry planar magnetic headphones.
