What is the difference between co-axial and a 3.5 mm interconnect? It can be just the ohms required, can it? Are they wired the same?

Mojo actually has three independant thermal cut outs a special high temperature battery and very sophisticated charging circuitry . Picking up on an earlier post Mojo actually does not dissipate a lot of heat when it's working. It's only about 1.7 watts and when it's charging it adds about another watt so its not much really. However the electronics and battery are thermally bonded to the aluminium case. The Mojo's case can only shed its heat through convection or by radiating it away. This can only work if there is a temperature differential between itself and its ambient surroundings if there is an insufficient gradient between them, the Mojos temperature will rise until there is a large enough difference to pass its heat to the air surrounding it.
If it is prevented from doing this perhaps by being insulated I some way it's temperature will rise until one of the three shut down trips operate. note the battery is safe to 150 degrees and the trips all operate up too a hundred degrees lower. Therefore it's perfectly safe. In fact if it's feeling mildly hot at first to your hand. Your hand alone will easily soon bring the unit down to a reasonable temperature.

Thank you for adding this. (It was a little of post 5862, and then posts 5863-5 that were discussing this. Then post 5867 echoed the impression that it gets quite hot when charging and running.)
 
I appreciate that all the details you laid out have been covered before. I think technically the battery charging curcuit is brilliant. I mean in regards to being able to use the Mojo as a desktop DAC. Thinking in desktop mode, I understand that once charged the battery is not drawing power, until it loses a little. Therefor it will run quite cool in desktop use. I would be thinking about using the batery charge now and again. It's advisable with re-chargeable batteries, to discharge the now and again.
 
After having been used in a portable way, the Mojo could require use and charge at the same time. Considering some people were showing concerns over temperature I worried how it might be in summer. For charging and using at the same time. It does seem like you are suggesting it will be OK, and unlikely to cut-out. Cutting-out is my worry.
 
I also would not be averse to fitting it with a heatsink. I think it would look great. If in summer if it got hot I would not mind placing a fan near it when next to my PC. There are plenty of small noiseless fans which will run from 5V USB power source. I have a heatink which I rescued from a dead motherboard. It measures 5cm x 4cm x 3cm (height), picture added.

Hello, I've followed this thread from when I first heard of the Mojo and it has spurred me to post briefly.

I received my Mojo today and I am totally blown away by its performance! I might well be alone on this thread in what I listen to, which is predominantly technical death metal. I thought for years, I'd have to put up with a lack of detail when things really get going but after listening with this device I'm pleased to say this is no longer the case. As people have already reported, I'm hearing detail that I seriously never thought I'd hear without going to a live concert. I honestly cannot give enough praise to this little unit, I can't even begin to describe its impact and I've only used it for six hours.
Can you tell I don't do reviews!

Having used it as I say for six hours, in my pocket with iPhone 6 and Tidal, I'd say it was rather warm to the touch. I mention this as I live in the tropics, and it was 34 degrees today and the Mojo didn't die on me so I'm thinking the English summer won't do much heat-wise ;-/

Thanks to Chord for making this wonderful device and thank you very much to you all on this thread for pointing me in the right direction and getting me started before I even got my Mojo on

P.S. My power and volume buttons were nice and loose straight out of the box, bonus for not needing to stress about sticky buttons

Hi

I've just picked up a Mojo and have to say I think it really is a miracle of engineering to produce such sound quality from a tiny box (I was amazed how small it was when I opened the box) it really has made an amazing difference to my full size cans (HD700 and HE400i)

I however have a query regarding DSD files, according to the box and manual the button should glow white when playing DSD files however mine seems to glow the light pink colour which is supposed to indicate 768khz this is from iPod touch using Onkyo HD player, anyone else noticed this or have any ideas why ?

Thanks, Carl

 
Just bumping this, anyone have any ideas re the DSD playback ?
 
Also anyone in the UK know where I can get a Coax digital cable with mini jack on one end ?
 
Cheers, Carl

Sennheiser HD600s. Hope to try some HD800s soon.

 
Cool, same here, have you tried the HD600 directly to the Mojo?
I find that the Mojo can drive them and a slightly more details comparing to the crack head. I have to compare properly tho.

Finally settled on my portable setup seeing as my 128GB S6 wasn't doing anything.
 
Really nice & portable for my offline or streaming (Tidal/Spotify) with some select Hi-def/DSD tracks via UAPP app. The Mojo Buttons are protected too from accidental change. Weight at 345g but sound out of Mojo so much nicer than the Sony ZX2. I don't have a SIM in it or you get too much interference but none over wireless (plus can hotspot to my phone with SIM in it anyway).
 

 
Solid connection with Heavy Duty Velcro

No worries as long your DAP or source has a regular mono 3,5mm ouput you can use regular short (> 10 cm) stereo 3,5mm to 3,5mm audio cables. No need for real coax cables with 75 ohms, as long the cable keeps as short as possible.
 
Like iBasso DX50/DX90, old FiiO X3 or X5 all have coax mono output and can use a regular 3,5mm stereo cable for the Mojo.
 
If you use i.e. the new FiiO X3 2nd Gen / X5 2nd Gen or Shanling M2 the use a different coax output and a regular stereo cable will not work.
 
I use a cheap FiiO L17 cable between my iBasso DX50 and Mojo works perfect, zero issues.

Okay, tell me the truth - is the Mojo a better sounding device - and a smarter investment - than an ak240? (Given I could add any old player (like the ak100 or the x3ii) for source). Cause I'm getting second thoughts here - I was supposed to get a 240, but now it looks like the game has changed...
 
Would be using it with Angie or Dita The Answer Truth Edition.

Personally, I think the Mojo sounds better than any of the AK players including the 240 and the 380 even with the external amp.

I'm driving my Mojo with an old AK120 (since it has two storage slots) and am extremely happy with it sound-quality wise. If I didn't already have the 120 I'd likely have snagged one of the AK100 TTVJ was selling for $375, since it's a better fit if you stack them.

Definitely agreed. The combination of Mojo and AK100mk2 sounds perfectly to me via Sysconcept optical cable better than X5+Mojo or iPhone 6+ and Mojo.

Is amazing how good Mojo sounds for only £399.
Finally an audiophile device made affordable!

An emphatic yes IMO. The Mojo, to these ears, is MUCH better than the AK240 when volume matched SE or balanced with the Angie.

The Mojo completely licks the AK240.

Wow. A nice spread of Mojo endorsements today
 
I've just pulled the trigger and ordered a pair of T1's... will advise how they sound with the Mojo early next week hopefully. I am cautiously optimistic!

George, this is how a coaxial cable looks inside:





Note the dielectric (non-conductive) material between the signal and ground. Also note the extra shielding on the outside. The difference is that a regular interconnect will not have the shielding around the outside, and the ground and signal wires aren't as isolated in a regular stereo interconnect but at these very short lengths the differences should be negligible.
