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
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
iFi 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.
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)
- 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 iFi 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!) |

The Pro iDSD Signature has a ‘quad stack’ of Bit-Perfect DSD and DXD DACs by Burr-Brown. The ‘interleaved’ configuration means up to 8 pairs of differential signals can be used and mixed, equal to 4 pairs of signals per channel. |
|
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. |
|
Upsampling to DSD1024 has previously only been available to a select few. The iFi Pro iDSD Signature makes it available to a wider audience. The DSD1024 remastering is handled by the Crysopeia® FPGA and this is where we believe the FPGA excels. |
|
Data is sent to the Memory Buffer from all inputs. Here it is de-jittered to eliminate any transmission of source jitter to the DAC output. The data from the Memory Buffer is further re-clocked by the low-jitter Global Master Timing® clock, which also drives the X-Core 200 and FPGA. |
|
With LINKPLAY™ WiFi/network playback, built-in Spotify and Tidal, and wide protocol support for 32-Bit/192kHz and DSD64, the Pro iDSD Signature can be also used without a computer to stream audio directly. |
|
Galvanic isolation is the ‘holy grail’ of computer audio.
All inputs are galvanically-isolated (including USB). The USB input section has its own separate power management system with multiple regulators and filtering operating from the galvanically-isolated voltage generated to power this section. |
|
Unlike other amplifiers that have the same circuit and just switch in/out the tube section, the original Pro iDSD and now the Pro iDSD Signature are among the very first to have two individual input circuits – one tube (General Electric 5670 tubes!) and one solid-state.
This results in the ‘best sonics of both worlds’. |
|
The amplifier audio circuit is fully discrete, fully-balanced with either tube or J-FET input switchable, bipolar second stage and MOSFET-buffered bipolar Class A Power stage. |

We’ve given the iFi Pro iDSD Signature an extra Tube+ setting. This reduces overall loop-gain and negative feedback to the minimum and presents a different sonic perspective between the tube’s natural harmonics and transient performance. |

The iFi Pro iDSD Signature is packed full of premium components – a Japan Alps rotary volume potentiometer, audio-grade ELNA Silmic capacitors and a bank of Elna Dynacaps ‘super capacitors’. |
