Is it worth hooking up a Chord Mojo DAC to a Hi Res music Player

    I have a Chord Mojo and I have just now added a Astell & Kern AK70 as a music source to replace the digital output of my Samsung Note 8 phone.

    I have output the AK70 using the provided AK mini USB-USB Cable which I have then attached to a Female USB - mini USB to connect into the Mojo DAC.

    So far I see no better music quality at all compared to either the AK player alone (giving a warm clear sound) or the Mojo alone (giving a rich and separated sound imo).

    If anything the combo just sounds clinical bright and lacking any character; and I mean that in a bad way I.e. not 'reference'.

    If I was in any doubt, the quality indicator light on the Mojo is showing Red which means worst quality possible.

    Maybe this means I have hooked it up wrong or maybe they just don't work so well together.

    If I cant make an improvement I would be tempted to sell both pieces and maybe put it towards a £700 Chord 2Qute (rrp £1000 - seems great value) or upgrade to a £1200 Chord Hugo (rrp £1400).
    Not convinced the Hugo 2 is the best value as it still retails at the rrp of £1800.

    Can anyone help?

    If your Mojo is showing Red that reflects the sample rate etc if your music files.

    I personally wouldn’t link a Mojo to something like the AK70, there probably isn’t much difference in the quality of the DAC that your bypassing.
    You should see a bigger difference when the Mojo is connected to your Note 8, that phone should support USB OTG this will give the full benefit of the Mojo.

    The mojo does not have the ability to play music without a source or the aftermarket poly attachment, so it reads like you are saying

    AK70 dap or note 8 + mojo are both better than AK70 + mojo

    But in this scenario the AK70 is only a transport for the music source files and nothing more as you say. It is possible the output on the AK70 is not up to scratch (to your ears)
    What is the usage intended to be? What will be the transport source?

    The note 8 alone or AK70 alone are pocketable. Adding the mojo means a big pocket is required. Spending money on the bigger chord pieces is not in reality pocketable but is portable with a bag.

    My advice is to go to a specialist headphone store to demo and not to buy blind, I have personal experience of visiting and buying from

    Chord DAC's are all highest quality engineering, though I personally do not like their cold, metallic sound.
    That being said, I believe these days there is a much cheaper, convenient alternative at hand.
    Samsung Note 8 or 9, Galaxy 8 or 9, LG G6 (Asian model) G6+, V20 or V30 are mobile phones with a hidden talent! (to my knowledge)
    They all have TRUE HD audio available to them, but are somehow hidden!
    The LG models mentioned have quad Cyrus DAC chips (AK70 has one Cyrus DAC chip as opposed to four), capable of playing any bitrate from 44.1 to 192Kb/s, 16 24 or 32 bit. The Samsungs can also play DSD natively(not a big-ee).
    Sound quality from these devices, when correctly setup, is second to none.
    Add the fact that they are fantastic smart phones, with SD card slots (256GB+), one can see that they beat carrying multiple devices with tiny screens with limited capacity.
    Here is the catch:
    To my knowledge, the only software that can truly playback HD audio natively (anything above CD standard) on these devices is "Neutron" when properly setup.
    This software can access the DAC directly and ouptput HD audio at native bitrates and sample frequencies to the DACs, bit-perfect but setup is tricky. DSD files can be transcoded on the fly to PCM at any bitrate/frequency you set it at.
    Neutron must address this tricky setup feature.
    BTW - I am just a happy (sort of) Neutron user and have no affiliation with them.
    Software costs a few pounds only - cheap as chips.
