The Pro iDSD Signature is our new flagship reference class DAC and then some! The Signature edition builds on the strengths of the original, multi-award winning Pro iDSD.

It continues to cater for those who love good music delivered at the highest quality.

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 aluminium 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 the your music to 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.

  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.
  
  

  Power cleans. Absolute.

  The Pro iDSD Signature ships with our 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 – we left no stone unturned in our quest for the cleanest, purest, power for the Pro iDSD Signature (same for Pro iCAN Signature too!)
