IFI Pro IDSD Dac/Music Streamer
IFI Audio have now launched their DAC-cum-music streaming device, the iFI Pro iDSD.
The iFI Pro iDSD uses a Quad ‘stack’ of Burr-Brown Bit-Perfect DSD and DXD DACs in a custom ‘interleaved’ configuration, which enables a total of eight pairs of differential signals to be used and mixed – that’s 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 parent company AMR’s DP-777 DAC.
Digital processing is handled by an 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. All inputs (including USB) are galvanically isolated and the USB input is self-powered. With LINKPLAY™ Wi-Fi/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 playback.
If the Multibit DAC is one half of the ‘heart’ of the Pro iDSD’s digital engine, then the other half is the Crysopeia FPGA (field-programmable gate array). It handles the up-sampling duties to attain the DSD1024 audio format. In fact, the Pro iDSD can handle all audio formats to DSD1024 or DSD512 or PCM 768K with user-selectable digital filters. The retail price of the Pro iDSD is US$2,499 (ex-tax) or €2,749/£2,499 (incl VAT).
