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

    It took me ages to get used to the Mojo.
     
    At first I found it hollow, cold, and thin, however more detailed than my other DAC. Since it was more detailed I persisted with it for a while suspecting some burn-in. (Or brain burn in which some suggest.)
     
    After about ten days I noticed it seemed very smooth, because there were no rough hiccups from poor  quality conversion. After that uphill moment, it continued being all uphill. I adjusted or it adjusted and it was all that everyone says it is.

    Thank you, for being both prompt and informative! So inconsistent, non-linear timing inaccuracies are what cause problems in how we perceive the sound? That is surprising, since the opposite is true with adding dithering. There the randomness is what makes dithering next to being INaudible! Are we maybe talking about two completely unrelated kinds of audio processing in our brains?

    Any deals this weekend on a mojo case?

    The longer case will be available shortly. Unfortunate there was no way we could acomodate the simple adaptor or far more importantly the next far more complicated adaptor without increasing the length of the case.

    Will the SD module be touchscreen? Will it have a screen at all?

    Yes, exactly like you wrote  "hollow, cold, and thin".
    But,  I believe in break-in. I did a lot of tweaks with my tube amplifiers and I built from scratch my tube phonostage.
    I can say, that even brand new cathode resistors (are shunted by capacitors) sound horrible during breck-in period.
     
    I listen Mojo in my system with 300B amplifier and Altec 604E speakers.
    I also listened Mojo with Audeze LCD2F.

    That's a huge possibility too. These devices most likely also prevent additional RF noise from getting into the system in addition to lower jitter levels. 
     
    Hans, from the Hans Beekhuyzen Channel posted a video review of the remedy and also took measurements of jitter levels before and after. He hooked up the remedy to the Mojo and found a very noticable lift in sound quality. If this was not entirely due to a reduction of jitter than it must have also prevented more RF noise from getting in and hardening the sound.

    I think you're on the right path so to speak. As time went on the Mojo just got better everyday for me.
     
    The hollowness I experienced turned into incredible sound-staging on my desktop speakers, (which are Q Acoustics BT3). My old DAC was a warm, thick, (and almost fluffy sounding) Meridian Explorer (ME). It's a good enough DAC at its own price point, but I knew I wanted more. The Mojo is much deeper in the soundstage on speakers, and that was what I was hearing as hollow. The Mojo also fills out the sides of the soundstage with equal details as anywhere else.
     
    Whether or nor burn in of the Mojo took place, Rob Watts says no. He says it's brain burn in. I think brain burn-in really happened for me because there was a substantial difference between the Mojo and ME. However we always hear about hardware needing time. When I eventually came to terms with how much better the Mojo is though, I realised it took time.
     
    To me the Mojo no longer sounds thin. It's just that the details and effects on sounds are more spaced out. Whereas the Meridian Explorer left everything flatter in soundstage back to front. (To me the Mojo now today, sounds full and solid.)
     
    It took me about ten days of lots of listening before I began to feel the Mojo was smooth. This was due to detail and it never going out of tune or harsh. That's a lot of running time. Fast forward a few more weeks and I accepted the Mojo.
     
    There is also a really important aspect that giving the Mojo bit-perfect files makes a real improvement too. This I discovered a few weeks in with the Mojo because I was reading this thread. I bought JRiver so I could access bit-perfect files. This improved warmth and timbre: well everything really.
     
    Fast forward again a few more weeks and I was felt the Mojo was worth its price, just. It was sounding analogue and a beautifully comfortable warm, and smooth. A few weeks after that and I felt the Mojo was part of my life. Now I don't know if I could live without one. (If you can imagine going back to an ME after getting used to the Mojo.)
     
    As it says at the end of the What Hi-Fi review of the Chord Hugo. "You'll wonder how you ever managed without one."

    Well,I will add even more cable length.
    Average velocity in coaxial is around 5 ns per meter (5us/Km).
    Therefore a delay of 100us can be obtained by using 20Km of cable. :wink:

    Anyhow I do like Rob's cable analogy when dealing with delay only:not impedance, not losses,etc...
    If continuous and steady that delay is not audible. If randomly varying such delay is audible.
    Thanks Rob.

    If you tie a knot in the cable, it can confuse the signal and sometimes it can't find it's way to the end [​IMG]

    Attention, i-Device-users:    Have any of you tried this cable yet?:

    (This is not the same vendor as the TaoBao one that's been listed in post #3 for the past year)
     
    It probably works fine, but I'd like confirmation from a Mojo owner before adding it to post #3.
     
    Cheers, all.

    My my, my Mojo is sounding so good tonight! :)
    Gone for a different bunch of music and streaming Amazon Music, "Top Songs in Prime" playlist from Thursday. Not normally artists I would choose but they sound so good.
    Oh ******, battery is on a Red light. LOL. Blimey.

    I was just looking at cheap tablets in the Black Friday sales. Do tablets run out quicker on battery when sending bit-perfect data by USB, like phones and DAPs?
     
    The Amazon fire will do about 7 hours generally . The Acer Icona 8 will do about five and a half hours generally.

    Aww, snap! I fell for it :rolleyes:



    Are you expecting it to suddenly pop up, Chris?

    :wink_face:
