    I use this USB cable: https://www.amazon.com/Monoprice-3-Feet-Micro-24AWG-Ferrite/dp/B002GH8OCG/ref=sr_1_3?keywords=monoprice+ferrite+micro+usb&qid=1565365650&s=gateway&sr=8-3&th=1

    It is well shielded, comes with a ferrite and it's only USD 5.

    I can also recommend this OTG: https://www.amazon.com/UGREEN-Adapt...5366032&s=gateway&sprefix=otg,aps,177&sr=8-15

    I use an iFi iSilencer3.0 (a little bit better than a jitterbug, in my opinion) between the OTG and the USB cable.

    I used to have this cable as well, it's great for the price, and sounds slightly smoother than the stock cable.

    Doesn't the iSilencer reclock the signal, thus adding it's own distortion?

    To me, the Mojo stock without that gear, with USB, sounds thinner than my laptops onboard sound. More refined with better separation etc, sure, but thinner.

    The iSilencer has an "active noise cancellation" filter but doesn't reclock the signal.

    I don't recall anyone else mentioning it.

    I will buy it and report back soon.

    I'm getting great results with JB + Curious Hugo Link - I'm sure there are many options
    out there, let your ears decide if at all possible.

    ''REBalance® literally rebalances the signal to address the common problem of clicks caused by jitter and distortion in USB signals. Our technology adjusts the signal to get rid of this unwanted noise.''

    Anyway, what sonic difference have you found between the Jitterbug and iSilencer?
  10. Totoxio
    Rebalance is a confusing term. iFi Audio uses a lot of catching words for marketing reasons, I think. In other sites I found that REbalance means DC offset removal (maybe just a capacitor). Other terms they use on some other products are "REgenerate" and "REclock". I think these two should mean the same, since reclocking means also regenerating the signal. But iSilencer doesn't reclock, I'm pretty sure of that.

    In the brief time I had the JB, I found that the iSilencer was a little smoother, and more detailed (darker background?) but really just a little. There's an interesiting post with some comparisons here*: https://audiophilestyle.com/forums/topic/30593-group-test-usb-gadgets-aq-jitterbug-uptone-regen-ifi-iusb30-ipurifier-ipurifier2-update-on-p15…/#comments

    Note: The second graph shows a comparison between Jitterbug and iPurifier v.1, which is now discontinued. The comments on the iSilencer3.0 are on page 15.

    *This is on another forum, I really hope this doesn't represent a problem with the moderators here. In that case, I'm sorry and please feel free to delete or edit this post.

    Well that's first for me I've never heard mojo sound thin no matter what its connected to or with and to top it off it's being used with a headphone that's known for its thick meaty sound, HD650.

    Maybe your laptop is eq-Ing the sound - and its adding bass?
  13. dakanao
    I have no DSP's actived with my onboard soundcard. But ofcourse the bass is more distorted, and can appear thicker that way
  14. adeseaso
    Yup, my phone and laptop have more bass than the Mojo too, but it's not a good sound.

    But I don't think it's as simple as 'the Mojo is too clean for bass impact', because side by side the Hugo is such a nice upgrade in the bass department with significantly more oomph, despite also having a more extended treble that may work to skew the impression in the other direction.
  15. dakanao
    With the additional shielding gear I've bought, the bass is way more punchy than my laptops soundcard, when it's in the recording.
