Chord Mojo(1) DAC-amp ☆★►FAQ in 3rd post!◄★☆

[griff2]

   
This is head-fi, anything goes. 

If you're using the line-out it's not double amping, it's using a better/alternative headphone amplifier to drive the headphones.  In my case I'm using a Ray Samuels SR-71a which through my headphones is a significant improvement to the Mojo's built-in amp.
 
If, on the other hand, somebody's using the headphone amp in non-line-out mode to feed another amp, that would make no sense as noise and distortion will be compounded.

 

[Mojo ideas]

No that's not the case for Mojo as the fixed output setting is just a set output voltage level. We don't need to bypass anything as our digital volume control is part of the Dac's noise shaper and it adds no measurable or discernible distortion

Is there any plans to release some official otg cables?

JF yes we will shortly have two cables blister packs one Andriod one Apple. They will have various bits of getting you started hardware rubber bands and the like. We can't advise a price yet as we don't know ourselves.

Will the apple cable contain a chip to negate the need for the CCK cable?

It would be great to do away with the CCK.

Isn't there a reason why Digital out from ZX2 battery life is greatly reduced ? Like high quality reading and current drawing for example ? There has to be a reason !

My Mojo arrived yesterday from Peter Tyson(excellent service).
 
Using with the LG G4 and Angie earphones.  It's a truly wonderful combo and sounds lovely.  Also sounds really good with my other phones - Oppo PM-3 and Fischer FA 4xb.  
I'd say it is a step up from the Oppo HA-2, just seems more detailed with a bit more air to the music.
 
Now here's a wee question for you all.
 
I've used some good Dap's in the past including the DX100, DX90 and ZX1.  I decided a while ago to stick with the smartphone/Dac combo however I am tempted to go the Dap route,  what would be the advantages of doing this with the Mojo over using my phone?  Is it better sound quality from the optical on a AK120 or other Dap than the USB on my phone?

optical sounds detailed with leaness. Coax sounds fleshy slightly covering some details. USB is in between. thats my view

Is it true that using a DAP like AK240 toslink out sounds better than a Mobile phone?
What I understand is ak240 might be cleaner as there are less processes used for WiFi, Android background program etc in a mobile phone.

JF here Yes it would but I'd posted earlier about this the guys a Cupertino require a complete and painful disclosure of any design that intends to accommodate their chip. If we had nothing to lose, say if we had little or no technology to hide and were using an industry standard chip we'd have no hesitation in going open book with our design but obviously we have Robs design to protect. So for us it's just not an option. Our adaptor when it's available will swallow the bulky end of the camera adaptor leaving just the tail to be less untidy.

Just please ensure the adaptor is large enough to engulf the sony otg cable as it is considerably larger than the apple official dongle. Thanks in advance.

Interesting.  Does the digital volume control vary the bit depth?

I personally liking the USB more, it is more clear in contrast to hugo where i like the optical more.
 
I got a couple of friend who liked the coaxial more than all the other connection, I can't test that so I guess stick to what sounds best for you and stop worrying

The same happened from the Note to the Fiio X3, the X3 was drawing current from the Note to charge the battery in the X3.  Connecting the Mojo desn't do this so I'm assuming it's because the USB audio in isn't connected to the charging circuit.

sounds good. Seems like this is only the beginning.

Opinions welcomed...will I be gaining greatly by adding the Mojo to my AK120ii?
