IFi Pro iDSD Signature

DAC | HEADPHONE AMP

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.

• MQA decoding

  The Pro iDSD Signature is an MQA Decoder.

  This enables you to play back MQA audio files and streams, delivering the sound of the original master recording. The LED glows green or blue to indicate that the unit is decoding and playing an MQA stream or file, and denotes provenance to ensure that the sound is identical to that of the source material. It glows blue to indicate it is playing an MQA Studio file, which has either been approved in the studio by the artist/producer or has been verified by the copyright owner.

  MQA rendering technology (used in the original ZEN DAC among other iFi products) connects to an MQA Core signal (such as TIDAL) and completes the final unfold of an MQA file. Usually, the computer has carried out the 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

• DSD (Direct Stream Digital)

  DSD is a very high-quality digital audio format that’s even better than CD quality. The higher the ‘DSD rate’ – DSD64, 128, 256, 512 and 1024 – the greater the amount of music information available, which means better sound quality.

  Files can be remastered to higher file rates to improve sound quality. The pinnacle of this is DSD1024. Not many machines out there are capable of this feat.

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

• Solid-state 'v' Tubes

  A solid-state amplifier uses electronics such as diodes and transistors to amplify the music signal. A tube amp uses valves/vacuum tubes to do the same job.

  There is a noticeable sound difference between the two methods. Some feel that tube amps create a warmer, more musical tone. Some companies choose to build ‘hybrid’ models that combine the two methods.

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

• Gainis the amount of increase in audio signal strength. Gain is often expressed in decibels (dB).

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)
• Use DLNA network audio playback with smartphones, tablets, Windows/Linux computers
• Connect to a hard disc drive (HDD)
Pop in a USB memory stick or SDHC card

And with a variety of headphone outputs – Single-Ended 6.3mm, S-Balanced 3.5mm and Balanced 4.4mm – the only choice is your choice.

XMOS XU216 X-Core 200

The Pro iDSD Signature employs the new XMOS XU216 X-Core 200 Series 16-Core processor. All-digital processing is Bit-Perfect unless particular digital filters are explicitly selected.
