    Welp, I can't tell you that you're wrong, if you hear things that way.

    I think that iDSD BL Nano is a better long-term investition, but iDSD BL Micro is way above Mojo in my honest opinion. More like worthy to compare to Hugo, and trust me, I really loved Hugo when I tested it, so this is not something I'd say lightly.

    We all hear differently. And we all are lucky to have this many wonderful devices to choose from.

    Don't know much about the Mojo, and I own (and love) the micro BL. But I recently auditioned a Hugo2, and it blew me away. So did the price tag.

    A question for xDSD line out mode
    could we utilize the TRRS S-balanced feature in Line Out mode?
    In other words, could we line out in balanced output to other AMP that accepts balanced source?
     
  10. Fawzay
    I was wondering why there is no Line In for xDSD as the device is dac/amp?
     
  11. Currawong Contributor
    I'd say because if you want a dedicated amp, it's best to buy a dedicated amp. The xDSD is obviously designed to be as portable a DAC/amp as reasonably possible.

    xDSD – Premium. Pocket-portable. Perfection.

    Part 2 – Loaded with Technology

    We are our own sternest critics when we develop new products. Partly because of customer input and sometimes just because we can, for the sheer heck of it, we like to see how far we can push the technology envelope.

    The xDSD epitomises this. This section provides an in-depth explanation of its technology and features – and why we’ve done what we’ve done so that it is both easy to use AND sonically stunning, as is the AMR/iFi way.

    Multibit Digital Engine with Amr Global Master Timing

    [​IMG]

    The xDSD is very much akin to the micro iDSD Black Label for a perfectly valid reason. Both products are based on the Burr-Brown DSD1793 D/A converter chip and share extremely similar digital and analogue stages.

    The digital section of the xDSD is drawn from the micro iDSD Black Label with DSD512/PCM 768 compatibility with DSD via DoP, native DSD playback, USB type A and S/PDIF inputs, XMOS-based USB circuitry and clocks derived from the micro iDSD Black Label with zero-jitter operation courtesy of the AMR Global Master Timing (GMT) clock, re-clocking and data management.
    [​IMG]

    The Bluetooth section inside xDSD is derived from our Retro Stereo50 and is also subject to the AMR GMT clock system that operates with femto precision. In the xDSD, the clock domain not only covers USB, S/PDIF and Bluetooth, but also synchronises the MCU (Master Control Unit) – effectively, the entire digital functionality of xDSD is slaved to the GMT clock system. It is global by name and by nature.

    Remap – Optimise for Mqa or Non-Mqa Formats

    We do not do things by halves. We write our own software code so the xDSD will launch with two specialised XMOS firmware versions.
    • v5.30 – pre-installed and optimised for MQA
    • v5.20 – is optimised for music file formats up to DSD512/PCM768 (non-MQA)
    Each firmware version squeezes that last ounce of performance from the xDSD to suit each customer.

    [​IMG]

    Just as car enthusiasts load different ‘remaps’ into the ECU (Electronic Control Unit) for their preferred driving experience, we let our customers load their preferred ‘file format remap’ for their own music torque curve.

    S-Balanced Optimised for Balanced IEMs

    Our exclusive S-Balanced technology extracts the maximum performance from single-ended and balanced headphones alike:
    1. With TRRS, the benefit is full dual-mono with grounds separated all the way to amplifiers. Just like audiophile hi-fi systems.
    2. With TRS, you lose the full separation of the grounds, however, by having two contacts on the ground crosstalk is reduced by 50% over a standard single contact socket.
    [​IMG]

    With S-Balanced, a dedicated negative wire per channel all the way to the star-ground of each channel’s amplifier to ensure there is no crosstalk between the channels.

    Plugging in unbalanced headphones with a TRS connector instead of TRRS will cause zero issues and, in fact, there is only upside as crosstalk is cut by 50%, compared to using a TRS socket.

    [​IMG]
    All the benefits of balanced, with none of the drawbacks.

    And for those who wish to connect the xDSD to a home system, the xDSD can be set to line out mode. Its 3.5mm headphone jack is converted into a fixed 2V level 3.5mm line output. Needless to say, the xDSD remembers its settings as you left them so you can turn it on and pick up from where you left off.

    Stay tuned, there's more!

    My short review for iFi xDSD :
    *im listening the xdsd as a USB DAC*
    This device really emphasized the details in the background within or the circumference of the head-stage. Im listening thru my iem: V -shaped, known for its heavy bass and sharp treble, however, xDSD really cover all frequency spectrum. im getting smooth and controlled bass and the treble surprisingly easy to listen although i apply the 3d+ compared to my micro idsd BL; its 3d+ to me, it just give a treble boost.
    However, xdsd 3d+ is really indeed gives the 3d effect, sound stage indeed extends a little but it extends in all axis. XBass+ of xdsd is same as the micro idsd BL, it does give the more bass effect rather suffice not so overpowering.
    The Bluetooth function it does connect but require few tries then it has successful connection, sometimes it got disconnected when no music playing/idling. Im indeed surprise the sound quality coming from a Bluetooth (known to have worse quality than the wired one)
    Hisses can be heard when music is not playing.
    i haven't really delve into to much on the digital filter, but i set it on measure as it give the whole music a "fun" feeling vibe.
    Overall, xdsd is analytical, natural sounding and balanced device.
    ifi xDSD > Fiio Q5 < Fiio X7Mark2
    ifi xDSD < ifi Micro iDSD BL
    Chord Mojo =/> ifi xDSD
    Hugo 2 ......... i dunno i wanna believe ifi xDSD is almost there at the Hugo 2 standard......
