I am new to the club just got my Mojo today got it on impulse in 5minutes after reading a review. Until now was listening out of a DX90 but lately I Made a DNLA WiFi music server out of a raspberry PI since I much prefer picking my music out of my drive I hate loading the SD!  I did try to use the DX90 as DAC on android it worked more or less on my tablet but not from my phone witch officially does not support USB Audio anyway total surprise I got it working on it  with a powered USB OTG Hub. I also fed the mojo thru coax and DX90 much better sound and not as analytic or dry
 
I must say I am delighted by the sound of this little beast, I am kind of exited just sharing my first few hours with my new toy!

What's the android phone you're using ? And do you have the brand of the usb otg hub with pictures ?

Many of us will recognise your excitement - for many it leads to revisiting music libraries/files that have been untouched for years, plus exploring new artists and music, because it all sounds so good with the Mojo.

A couple of hundred pages back, there were a few posts from members who have built Raspberry Pi docking stations for their Mojos. You may find the posts interesting (assuming that you haven't already read them). For example:

  Many Mojo owners have shown interest in using the new Shanling M1 as a music source for their Mojos.

Sadly the first batch of the M1 will not work with the Mojo via USB, but a promised firmware update will enable the support for Mojo.
 
More bad news is that the supplied cable will not fit properly into the Mojo USB socket, so Mojo owners will need to buy a new cable.

This all means that we must wait a bit longer for the first user reviews that mention whether there is good synergy between the M1 and Mojo. 

 
It looks like the beta software update works well, and allows the M1 and Mojo to pair. Just PM Shanling if you want to try the software.

These are cool. I need to get a 3D printer.

Those looking for a small transport/ source/ DAP for their Mojo may be interested in this post on the thread that Mython previously mentioned.
 
Edit: Oops right link now.

Thank you for the links they are very informative but actually my Raspberry use has been to steam the music over my network by creating a very inexpensive Nas with OpenMediaVault (OMV) like this but just with one drive  no Raid involve at this point.

This may have been said already, I have not been reading this thread for a few weeks, 
My Lavricable is now working with iOS 10.1 Public Beta 2. It was not initially working with iOS 10 release version.

Congrats Chord on your two 'Best in Show' awards at CanJam RMAF 2016 for Mojo and DAVE! :)

Thanks rob..appreciate your reply...maybe I'll go see an audiologist after all... hope other fly users can chime in on colours used per volume... am a bit worried.... but is '25 clicks of volume' in some normal / average range?


There are a few variables that need to be determined before one can say a specific number of "clicks." The first two are determined by the headphone/earphone: sensitivity and impedance. You should be able to get those values from the manufacturer. In the case of my Angie customs, the sensitivity is rated at 117 db/SPL @ 1 mW and the impedance is 17 ohms. Typically, I set the volume between 14 and 30 "clicks." If your 'phones has different specs, then you will need to use a different range.
 
The third variable is the average volume of the music, which will be different for each song/album. That is why I use such a wide range of volumes.
 
Depending on your 'phones, it is possible that 25 "clicks" could be damaging your hearing. I would encourage you to visit an audiologist.

14-30 clicks and 25 clicks with reference to what? The preset? Above or below?

But the guy above is right. You need the nominal sensitivity and impedance number along with the output level for people to make an apples to apples comparison.

I assume the output level is measured for a full scale input to the DAC, so you don't really need to share the mean value for your audio file..

I apologize for making an assumption... In this case, I assumed that a "click" is pushing the + volume button/ball once, with the number of "clicks" is counting up from zero volume (both balls are unlit). This usage of "click" has been used extensively in this thread.

No apologies needed. I've seen instances in this thread where clicks meant clicks down from the preset (3Vrms, not max volume). That's why I asked.

Not relevant to the discussion, but I actually prefer the reference to be the 3Vrms with clicks being above or below this value. Each click is a 1dB step, so it makes calculating the nominal output level much easier. Otherwise I have to figure out how many dB down from 3Vrms one click up from mute is and then add the remaining clicks to that.

yes guys...thanks.
my mojo is zero'd down to as low as can be...then i click the volume + button,
one by one, til the balls light up and start to change colours...
25 was the blue/purple..
 
and as per xrelic's helpful info:
 the Flc8 is 11 Ohm with a sensitivity of 93 dB/mW

Did anyone try the new B&W P9 headphone with the Chord Mojo? If so, how does this pairing sound?
