Those of you who have heard interference with phones: can you confirm it is gone with 3G / LTE?
Enyone can still experience it with 3G / LTE?


I found it worse with 2g etc but there is definitely interference with 3g/LTE, it is like a crackling sound in the background that you can just about hear during quiet bits in song.


Sorry no I don't think you can turn it off, I think any app that doesn't use it's own USB audio output protocol like UAPP, Onkyo HF or Hiby gets up-sampled automatically by the stock android USB audio out.
If you are running stock CyanOS like me make sure AudioFX is turned off also, this can effect the sound output.

I'll do some digging around to see if I can find a better explanation for you.


Yeah I disabled AudioFX straight away because it was causing a funny glitch at the beginning of the first song played in Spotify. Regarding the up sampling I guess it isn't the end of the world if I can't turn it off so I will just live in ignorance!

  Could it be damaging in the long run to keep the Mojo permanently plugged in as a desktop DAC? I understand that it runs hot and I'm fine with that; just don't want it to explode on my face!

 
Chord are not in the market of blowing-up Customers we'd rather see people enjoy their products but to dispel any fears, here's a message from Matt of Chord...
 
Mojo gets warm. nothing nasty or dangerous. It's probably cooler than most laptops (includes my own)... Mojo runs hottest when it is charging and playing at the same time but even then it is nothing to worry about.
 
Please Note: there are two separate temperature protection circuits which will switch off Mojo before it can get too hot, hth.

Anyone try stacking with a Fiio X5 using the Fiio stacking kit? That looks promising on paper and also would be the lowest cost transport with 2 micro SD slots.

Also any chance the 2 headphone output can be switched to balance like you can with the Pono?


The stacking kit bands land just outside the width of the Mojo so it's difficult to get them to securely stay (without sliding off). A single band below the X5 screen and in between the Mojo volume and power buttons is a more secure fit.

How about a thin sheet of silicone between the two? Or maybe cut out a shape from one of those things you put on your dashboard to keep your cellphone from sliding off? HTH

Also just ordered a used AK100 as a transport for the Mojo as well as a custom Toslink to mate the two (thanks for the link to Sys Concepts - they're super responsive!). 
 
Wanted to do some direct comparisons between my X3 via coax and an AK via Toslink. Realized that the AK100 is an almost perfect size-match to the Mojo and with 2 micro SD slots it can hold all of my music. Will let you all know how things work out. 
 
Cheers

Welcome to the club, you're at least the fourth person that has gone down this route, and - I'm now no longer the newest recruit :D

...Am going to place an order for one of the sysconcept cables on Monday I think, hope it is fast shipping to the UK :D

AK120 has 2 micro SD slots. AK100 only has one I believe.

How much of a realistic improvement is this over the Dragonfly. I don't want to hear hype saying it blows it away because I doubt it's going to be a massive difference. But being realistic, what would be the difference? I like the warmth of the dragonfly so I may just stick with it and grab a Project Polaris.

No, it does have two, like the AK120

Interesting. Maybe someone with the knowledge can make a quick post of the differences of the previous AK line. I just saw a "Titan" model and not sure what that is.

I bought a Titan today, it was the same as the original AK120, but with double internal memory (128gb) and a different paint job...

Personally I don't have an issue with anything sliding. I was replying to the question if the X5 stacking kit will work and in my opinion the bands might pop off and the Mojo will fall, and the owner will be upset. Here's a pic with the X5 stacking kit. Note how the bands are angled and not straight. The notches in the Mojo help hold the bands but I'd rather use a more centred one band solution. Personal preference I guess.

Awesome! Thanks for the picture. I think I know how this might work. One could apply small silicon feet on the four corners of the Mojo, but both top and bottom. This should keep the stack from sliding and also secure the straps better by placing them on the inner side of the silicon feet. Also good to put these on the Mojo for desktop use too.

Used to own a Titan, now considering going back down that route! Was the max file limit ever changed in a firmware update do you know, or do you still need to use folder view with a large library?
