Why not get one of the "compact" models, for a better stack? I'm considering the z5 compact for my next phone, and stacking this with the mojo for a decent iem setup, so I'm curious about your decision.

 
I wasn't sure if the compact models was the same spec as the big models  I was also worried they  wouldn't work with Tidal.
 
It would do for now.

  still wondering if it could be the cables i am using, one of them plays the 24/176 music sample from the AK PLAYERS and the other 2 dont all three dont play 192,I have a sysconcept cable coming this week hopefully that will solve the mystery.

 
Just a reminder to those people who are suffering with TOSLINK optical digital cables.
 
The cable quality (not price) makes a big difference, as well as the bend angle. (as much as the optical transmistter quality of the DAP).
The TOSLINK standard was originally only intended for up to 96kHz on the cheap single core plastic fibre cables, which is what most audio optical cables use, unlike the graded/multi-strand glass fibre on expensive data cables.
 
The older and cheaper TOSLINK cables have terrible tip roughness that also limits the max rate that it can safely feed. Even the expensive cables started having pop noises above 88.2kHz. Some of those I got to work at 192kHz by polishing the end cap, but not all were successful.
 
I can't recommend any particular brand of TOSLINK cable, and it's hard to tell because most of those cable makers don't make their own brand of cables anyway.
 
Attached are some photos I took many years ago FYI.

Van Den Hul optical van have enough bandwidth to even do DSD, great cable but hard to find in short length.

 
I tried the VhH and they were great but I didn't think they made the short 3.5mm to square cables that people want for Mojo.
Often the companies that make those 3.5mm to square cables are there for early niche market and not very reputable or good quality.
 
One of the big issues is that people often neglect the tip of the TOSLINK cable. It can easily get scuffed with micro scratches, as shown on my photos earlier.
A lot of companies put a glass or hard plastic "lens" cap on the tip to reduce the scratching, but that protrudes out of the square connector and gets scuffed as well.
 
I found the TOSLINK optical is one cable where the build quality and the dust cap is very important. At least the effect is obvious because the music either doesn't lock on or start skipping.

  Interesting thread with Mojo mentioned.

cheers for the link 'wirefriend' and to quote a post in part 'The Chord Mojo is quite an amazing device. It transformed my iPhone 6 to an Audiophile-Grade DAP. Oh yeah, the shift from DAP to Smartphones as the tool for enjoying Music has begun.'... think beemarman might be onto something in exchanging a DAP for a phone... the thin width of a phone paired with a Mojo (with cable-tidy modules) could be the ideal form factor with hi-end performance as the 'kicker'.

Hello anyone uses AK100, AK100II or AK120Ii with MOJO? I have a problem with my AK100II with MOJO.

I use Black rhodium Toslink and music files with sampling rate at 192khz and higher (including DSD) cannot be played with MOJO. MOJO's power button has no light and no sound when playing these files.

I suspect that the Black rhodium Toslink cable is likely to be incapable of playing files with high sampling rate 192 or above.

Any comment please?


Just a note that DSD uses less bandwidth than 192k. Toslink ... What has already been said.



played 24/192 on my mac via toslink to mojo and no go!(Audirvana)
plays ok withAudio technica AT-HA26D with same cable so I think that confirms Mojo cannot play above 24/96 via Toslink.


Apple computers don't allow more than 24/96 from optical due to the problems already discussed.

Annoyingly my mini optical to Toslink VDH doesn't work any more. I'll probably buying a new Sysconcepts one instead.

My phone contract is up for renewal in a month or so and I am thinking of going for the Sony experia z5 as it has 32gig onboard memory and capacity for 200 gig sd, and is obviously suitable for use with streaming services. Plus it's a considerably cheaper option than the 128gb iPhone alternative.

I'm using LG G4, takes SD card and can carry a spare battery, fantastic screen & camera too. Running Onkyo HF player with Mojo seamlessly.

Dont think so!you can play 24/192 on a mac using audirvana as i explained, using the same optical cable on a cheaper dac the Audio technica HA26A my tracks played ok.

Correct - https://support.apple.com/en-gb/HT202730;
 
"The audio hardware in some MacBook Pro, Mac Pro, and iMac computers supports 176.4 and 192 kHz digital audio.

 
These computers support up to 192 kHz sample rate for audio playback:
  1. MacBook Pro (Retina, 13-inch, Late 2013) and later 
  2. MacBook Pro (Retina, 15-inch, Late 2013) and later 
  3. Mac Pro (Late 2013)
  4. iMac (21.5-inch, Mid 2014)
  5. iMac (Retina 5K, 27-inch, Late 2014) and later
  6. Mac mini (Late 2014)
To set your Mac to play high sample rate audio:
  • Connect one end of a TOSLINK optical cable to the headphone port

     on your Mac and the other end to your audio device (for example, a receiver or Hi-Fi stereo system).
  • Open the Audio MIDI Setup app (located in Applications > Utilities). 
  • Choose your audio device from the list on the left side of the Audio Devices window and, if necessary, choose “Use this device for sound output” from the Action pop-up menu 
    action-menu-osx-icon.png
     .
  • Select a sample rate (for example, 192000.0 Hz) from the Format pop-up menu."
