Chord Mojo DAC-amp ☆★►FAQ in 3rd post!◄★☆

Discussion in 'Portable Source Gear' started by Mython, Oct 14, 2015.

    I'm talking about extremely loud alien noise that plays instead of the music every once in awhile, not stuttering.
    As for stuttering, here are my original comments from five days ago. Using a virtual RAM drive fixed that for me.

    I have the Sennheiser IE 800 and the JVC HA-FW01, both of which work very nicely with my Mojo. The JVCs are particularly exceptional at their price point.

    I had similar issues on DSD128/256 and DXD, but it went away after finding a good USB cable that works.
    More importantly, I had serious stuttering issues when I was using a USB3.0 port on my PC, and the problem went away as soon as I put a USB2.0 hub onto it. Maybe it's worth a try simply for the sake of diagnosing where the problem lies.
    There was some documentation I read somewhere that the USB3.0 has faster burst throughput but has more aggressive queueing and traffic management implemented by the motherboard chipset, so it was not ideal for a continuous flow of data that audio requires, particularly when other peripherals are connected to it internally (e.g. laptop trackpad, Bluetooth, camera, etc). My old Mac Mini had issues where the music would pop every time I used the Bluetooth mouse.
    Also on one PC motherboard I had to disable the power management entirely because DSD256 had pops every time the CPU clock wound down to economy state. I guess DSD256/DXD is pushing the limits of USB2.0 bandwidth, and exactly how the data packet stream is sent off to the DAC is entirely up to the chipset/OS design.
    Having said that, I haven't encountered these issues when using iOS+Lightning CCK+Mojo.

    This got me thinking, I listen to my music from my windows pc -> optical -> mojo. Are there any benefits to using a dedicated device like this? I thought about trying my mac mini but haven't got round to it yet.

    welcome to the growing world of USB audio, eh?
    who'd have thought of this stuff even 4 yrs ago?
    sorry but i'm not the best dude to answer that as I'm still wrapping my head around its purpose and capabilities (and limits)
    .basically if I'm correct it's a bridge that makes a reg USB into an audiophile USB.
    there is a thread towards it, too here:
    ...helpful people on there.
    from Darko: http://www.digitalaudioreview.net/2016/10/sonore-at-rmaf-2016-talisker-taste-on-a-teachers-budget/
    since it's computer audiophile related, BIG thread here:

    Do you know if there's a way for me to try the optical connection with my Alienware M11x R2 laptop? Perhaps via some sort of adapter cable?
    Apparently there are USB to optical adapters...but I dunno if I'd want to buy one just to see if optical sounds better.

    Did you try this Meenova Lightning to MicroUSB DAC cable instead of CCK + USB cable.

    Thanks for everyone's responses regarding IEMs and Mojo. For specific IEMs, I haven't done a ton of research yet but I would consider even the Layla II, which is actually the IEM that prompted the question as I have heard that they can be picky with what amp you pair them with (I hear they are unbelievable when paired with the VorzAMPpure II). Would anyone have any concerns with an AK100/Mojo/Layla II rig? 
  10. x RELIC x Contributor

    Concerns? Drive ability and output impedance is not an issue at all, far from even considered an issue. Sound preference is the only question. I absolutely love the JH Angie with the Mojo and I imagine the Layla would be just as enjoyable (for me at least). For reference, the Vozamp Pure II and Mojo have about the same output power.
  11. jwbrent

    The AK100 was a bit buggy and the volume knob was very wiggly, did not inspire much confidence in regards to build quality. You may want to take a look at the current model that sits at the beginning of the A&K lineup ... I believe it's called an AK70, and it too is a small design that would mate well with the Mojo.

    i have compared against modi 2 if that helps
    quick comparison, modi is better than any computer output but compared to mojo its much more digital sounding with harsher edgy treble. kind of explains the "schiit aggressive sound" people talk about. mojo is also better sounding than any other desktop dac iv heard up to £1400.

    damn mine has no code, it was purchased at launch [​IMG]
  14. maxh22
    Have you heard any of their Multibit offerings?
  15. Music Alchemist
    I had the Modi 2 as well and concur with your synopsis...except that I could not distinguish between the onboard DAC of my laptop and the Modi 2. Some computers are better than others.
    What's interesting is that all these DACs have a neutral measured frequency response, so the significant difference in sound with the Mojo comes from other things, such as timing accuracy and the lack of noise floor modulation.
