A Signature step upThe Signature takes the original Pro iDSD and pushes it even further towards perfection. The Pro iDSD Signature has:
E-tailoringThe 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.
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.|
|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’.|
