iFi Audio Pro iDSD Signature (DAC, Amp, and Streamer)

Use the Pro iDSD Signature as a standalone unit, a DAC/preamp, a network streamer, and a headphone amplifier.

A Signature step up
The Signature takes the original Pro iDSD and pushes it even further towards perfection.

The Pro iDSD Signature has:

• a sonically darker background and a punchier bass
• upgraded power -supply components to lower the overall system noise by 300%
• precisely matched NOS GE5670s tubes
• added support for USB1.0 (PS4/PS5)
• a new aluminum remote control
• a top-of-the-range iPower Elite power supply included

Stacked. With Tech.

The Pro iDSD Signature uses a quad-stack DAC – 4 x DACs in an interleaved configuration – to deliver exceptional resolution.

The powerful XMOS XU216 X-Core 200 series chipset processes incoming digital data and 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.

Thanks to the Crysopeia FPGA Digital Engine the Pro iDSD Signature brings studio-grade DSD remastering to a wider audience. 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.

Listen to your music in solid-state, tube or tube+ modes, your choice, all at the flick of a switch.

Our Crysopeia FPGA Digital Engine strikes again as it enables the Pro iDSD Signature to offer several options when it comes to digital filtering. 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.

Your choice. The only choice.

• Stream wirelessly from Tidal, Spotify, Napster, QQ Music, and more
• Use Airplay to enjoy playback from your iPhone, iPad, or Mac
• Go wired via an Ethernet connection to play from a router or NAS (Network Attached Storage)
