iFi Audio - Pro iDSD - compact headphone amplifier & digital-analogue-converter
Every section of the Pro iDSD has received massive attention to detail. Classic design techniques for very low-noise design found in tube equipment have been combined with cutting-edge, 21st Century technology to deliver a superlative performance.
Quad stack – interleaved Burr-Brown DACs
The iDSD Pro uses a Quad ‘stack’ of iFi’s Bit-Perfect DSD and DXD DACs by Burr-Brown in a custom ‘interleaved’ configuration. This enables a total of eight pairs of differential signals to be used and mixed – four pairs of signals per channel.
All signals to the DACs are re-clocked with the low-jitter Global Master Timing® master clock derived from the AMR DP-777 DAC.
The DACs operate ‘Voltage Output Mode,’ giving >119dB dynamic range. All filtering is passive, using a fully-balanced third order capacitor/inductor/capacitor filter, rather than active, feedback-based circuits, to remove ultrasonic noise. (Active filters struggle with the amount of ultrasonic noise and RFI they have to handle and at a few 100kHz they can lose the ability to filter noise at all, which is precisely where a lot of noise is present.)
Using passive CLC filtering directly after the DAC means that the following analogue stage is not required to handle ultrasonic noise and RFI originating from the DAC process.
Studio Grade Remastering DSD1024
For the first time, Pro iDSD brings Studio Grade DSD1024 remastering to the mass. Now one can remaster all his/her music to a superlative DSD1024 format just like in a recording studio and enjoy the ultra-high resolution it provides.
For the DSD1024, if the MultiBit DAC is one half of the ‘heart’ of the Pro iDSD’s digital engine, then the other half is surely the Crysopeia FPGA. This is where we believe FPGA excels, by handling the remastering duties to attain the DSD1024 audio format. In fact the Pro iDSD can handle all audio formats to to DSD1024 or DSD512 or PCM 768kHz with user-selectable digital filters.
XMOS 16-Core X-Core 200 with large memory buffer for all digital inputs
The Pro iDSD features the new XMOS XU216 X-Core 200 Series 16-Core processor,with a maximum of 2,000 MIPS (two billion instructions per second) calculation power in dual-issue mode as a USB interface.
All digital processing is Bit-Perfect, without employing ASRC or up-sampling unless digital filters are explicitly selected. It can decode signals from all Inputs, from USB (up to 768kHz/DSD512), AES/EBU or S/PDIF (up to 192kHz/24Bit) and Wifi/Network/Mass-storage (up to 192kHz/32Bit).
A variety of digital filters (including Bit-Perfect mode without digital filtering) are available.
All inputs (including USB) are galvanically isolated and the USB input is self-powered. The SPDIF inputs use technology derived from the AMR DP-777 including a new, solid-state implementation of the HD-VDi, memory buffer and the Global Master Timing® clock system.
Recording engineers please note that the Pro iDSD supports the AES3id-based DARS (Digital Audio Reference Signal) as recommended in the Audio Egineering Society’s published AES11 standard.
Femto Precision GMT Clock & Reclocker
For all inputs data is sent to the aforementioned Memory Buffer, which iFi describes as ‘large’ and ‘elastic’. 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 with the low-jitter Global Master Timing® clock, which also drives the X-Core 200 & FPGA.
Wireless Playback Engine
With LINKPLAY™ WiFi/network playback, built-in Spotify and Tidal, and wide protocol support for 32-Bit/192kHz and DSD64, the Pro iDSD can directly link to a router for online music play. This gives it the option to:
