    DIGI32 cost optimised high performance digital streamer

    After DAC32 and CORE32 the DIGI32 is our next family member.
    Like DAC32 it is based on the ESP32 processor and the fantastic squeezelight-esp32 community software.
    Instead of a digital-to-analogue converter the DIGI32 features a high performance S/PDIF transceiver chip.
    Again we took utmost care for fine-tune the surrounding audio related circuitry for best performance.
    There is a standard optical TOSLINK output along with an electrical S/PDIF one. It supports all standard resolution up to 96 kHz at 24 bits.
    Unlike most consumer graded digital streamers our electrical S/PDIF output is fully isolated to avoid any kind of ground loops ensuring highest signal integrity.

    We have learned from our two previous releases and this time there will be no pre-ordering but just a preview phase.
    So far it is playing really well and looking like the official release won't be that far away.

    If you want to be one of the first people receiving one please either send us a PM here or sign up on our website to receive a notification once it is in stock.

    No picture of the front face?

    Are those 2 LED's on the top right edge of the PCB?

    Hardly a cutting edge spec; not for me then

    For the record, the maximum resolution of DIGI32 is determined by the limits of ESP32 module, not by the SPDIF chip. The 24/96 limit is of course not an issue using the TOSLINK output, because this is the official maximum supported resolution.

    It is also worth remembering, that the ultimate performance of any product is determined by the quality of implementation. Just because a product quotes a higher resolution (sometimes determined by just quoting from the chip spec- not confirmed by measurement) does not automatically make it a better sounding product.

    That is not to say of course that there are not better products out there - its just that they will cost significantly more

    PS Just to be clear, DIGI32 will of course play stored 24/192 tracks using LMS transcoding

    Exactly the same as DAC32 on the front. Yes, those are two LEDs.

    What on earth do you need 192/24 for? Silly.
