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

    So the Sennheiser HDV 820 trick, just with reversed effect... Anyway, hard to believe – from an electrical point of view – that 1.7 Ω do enough on a 12.8 Ω load. Certainly not 6½ dB. Also, I wouldn't sacrifice the better DAC/amp in favor of such a crude equalizing method.

    Again, what do you think of the Atlas, compared to the Vega? BTW, I don't hear any hiss from the Mojo, neither with SE846 nor with Andromeda (which have about the same sensitivity). This with 68 year old ears.

    In terms of sound signature, Atlas has deeper bass and smoother treble without the sibilance that you get with Vega based on the Sony NW-WM1Z DAP’s output. It’s a tie for me where I prefer the Vega with EDM/pop while Atlas on classical (better mids and treble tonality for me).

    Vega has no hiss at all with Mojo but with Andromeda it’s very apparent when listening to quiet tracks

    Hi. Would you recommend ASIO over WASAPI ? Somehow ASIO sounds better in my opinion. I am using Mojo + Jriver. Tks

    Serial numbers in the 50.000s were seen, mine has 46.xxx and I bought it new this year, but from an Ebay seller in UK which could mean that it has been sitting around for a while.
    If someone really wants to know if a Mojo 2 is possible he could research if there's a new FPGA chip generation with higher performance at similar power consumption.
    That would be the precondition for an update of the Mojo.

    I already have a Hugo 2, but it's size makes it a bit much for pocket use.The HiFman R2R2000 is what I'm currently eyeing as replacement due to the streaming capabilities being exactly what I'm looking for in a new mobile dac/amp. However, it's firmware seems to be full of problems that do not reflect it's price point. So, I'm left dreaming of something from Chord of similar size and capabilities. Hopefully we get some kind announcement in the coming weeks.

    Bluebird certainly got a bad press in the early days, but have become more end customer focused, and contribute to the Poly thread, for example https://www.head-fi.org/threads/cho...on-1st-page-◄★☆.831347/page-443#post-14027958

    I used to get the odd clicks and pops on my Mojo, when connected to PC. When I bought a music player that allowed me to set 'bit-prefect' output, it cured it.

    Took a few weeks off from listening to Mojo, listened to it again yesterday and it still continues to impress and engage me. It compliments Hugo TT very well with its more upfront presentation.

    I recently got a pair of AKG N40 in-ear headphones. (MSRP £350, but often on sale for anywhere near £250.) They sounded a bit rough straight out of the box, (unless it was me). They had me curious. Maybe two to three hours later they were showing good colours. Now I have about twelve hours listening on them.

    The pairing with Mojo is perfect. For the price I can not imagine a better pairing. ... (The N40 pair perfectly with my/the Hugo 2 too. It seems to be a pairing with Chord DACs.)

    I always loved the Mojo and used for a couple of years before buying the Hugo 2. Since having a Hugo 2 I generally use that. I listen mostly with an amplifier and Dynaudio Emit M10 speakers on my desktop. The difference between Mojo and Hugo 2 is to me more distinguishable on amplifier and speakers. Probably because the sound-staging and spacing leaps out, and all those extra details in are in front of you with Hugo 2. The Mojo was good; very good. However it lacked just a fraction tonal neutrality in this pairing. It also pointed the way to what more detail resolution would be like.

    Bearing in both the Mojo and the Hugo 2 are components technically above my amplifier and speakers. Going on price performance. Mojo excellent for £400, Hugo 2 £1800, Rega Brio amplifier £600, and Emit M10 £500. .. It meant that the amplifier and speakers were holding back both Mojo and Hugo 2.

    I have a similar situation with headphones. My new AKG N40 are my most expensive and best rated. .. The point I am making is that the quality, pairing - synergy, and leap with the AKG N40 was not foreseen. I can't explain the synergy. It's just perfect!

    I already loved my Mojo and got an emotional response just seeing and holding it. The AKG N40 pairing is adding even more to that.

    I know I am experiencing this from one perspective. That being, I have only heard one pair of in-ear headphones at this price point. ... In all honesty and reality though, I can not imagine a better synergy - paring. ..... Music seems alive, wrought with emotion when needed, accurate, and finely detailed.

    When I change from the Mojo to the Hugo 2. The difference is a finer, smoother, more accurate reproduction. I get the obvious impression though, that better quality headphones would bring out even more with the Hugo 2. The pairing is non-the-less synergy-wise, prefect.

    Interesting, I'm the other way there - prefer the Andromeda with the mojo, not as much as a fan with the Vega (too thick/syrupy for me).

    We definitely have different ears and sound signature preferences

    I am experimenting an issue with the mojo.

    It’s in orange battery state.

    I turn on in level out mode and at the same time it’s on charge (2a charger).

    After 1 hour or less it... turn off!

    It’s the third time it happens.

    Why this behaviour?

    Possibly overheat protection.

    Does the mojo feel very hot, just before it shuts down?
    Charging your mojo from a low battery, whilst playing music will always generate the most heat.

    I calculate about 2dB from max attenuation in the bass to min attenuation at 8-9kHz based on this impedance response graph and 1.7 ohm output impedance
