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

Hi there ,
My Mojo arrived today, and I am having some issues and questions.
I am using the Mojo with my Asus padfone s via USB. I wanted to be extra smart and use a hard OTG adapter with USB female so I could use a jitterbug.(dont have one yet, so no impressions)
I have experienced disconnections via playback, and since I read the Faq now, I think the adapter / cable combination is the reason.
I read that Audio Technica makes a good 0.15m OTG micro USB cable.
Also still interested in the jitterbug implementation, maybe with another short micro USB to USB female cable instead of the adapter...and then I will get the Curious Hugo link .
Did anyone try eather of this or does anyone know if the jitterbug would work.

Please notice that this is my first post, also I am from germany...so please be gracious

I have already downloaded the foobar 2000; also added the DSD plug in for the software; have switched the mojo into line mode. Is this correct?

In Foobar on the File menu choose Preferences. Inside the dialog that shows up, click on the symbol that looks like this:

>

next to the word Playback. This expands the Playback section. In there click on the section called Output.

Now, just under the word Device over in the right-hand section, click on the drop down list. Inside that list choose the option "WASAPI (event) : Digital Output (Chord Async USB 44.1KHz-384KHz)".

I also recommend that you set the buffer length to 2000 ms. You can set the Output Data Format to 24 bit.

All of this only works if you have installed the driver for Windows.

Has anyone tried Mojo with Hifiman HE500 need to know if it can drive efficiently and get some feedback on SQ, also compared to Lhlabs Xfi how does it sound, if it can drive HE500 close to Xfi than I will sell my Xfi, go1k and DF1.2 to fund mojo ☺

Hello all,
 
apologies if this has been brought up before, but I have experienced a few dropouts in playback when using the mojo via USB with the supplied cable.
 
I've been listening to ALAC files via iTunes on a macbook pro.
 
Is this a common problem and could it be related to the supplied cable? Or something else entirely.
 
Any help would be appreciated.

Check midi setup and ensure it isn't set to something ridiculously high, try 192. For some reason mine by default was set at 768 and I had the same issue.

Thank you both for the fast replies,
 
I checked midi setup and it was set to the highest, I've now changed it and hopefully that will resolve the issue.
 
As far as cables go, are there any good alternatives people have found?
 
Mojo has just cut out again whilst typing this damn! Really frustrating.

Disconnect after changing settings and reboot the Macbook.
 
I have this cable, big improvement over the standard cable.

Try checking if it's the USB cable.
Connect it to the charger port, and have the white LED light up.
Try wiggling the cable and see if the LED goes off. If it does, it's probably the USB cable.
My supplied cable acted liked like this, changing to to another worked.

Again, thank you for the quick replies.
 
I've restarted the computer so will now wait and see.
 
I must admit, I like the look of the QED cable, 0.3 seems a sensible length as well.
 
Did you notice a sound quality improvement with this cable?
 
Thanks

Big improvement yes, worth a try, you can always return it if you don't feel there's any benefit

yeah man, i own oppo pm3 and pairing it with mojo...believe me...wow....mojo really elevate the sound of pm3, here's my impression :
pm3 direct with iphone 5 :
-its allready good
-low pronounce, but lack of thump impact
-mid good
-high good, detail retrieval not so good
-sound stage not to wide
 
pm3 direct with oppo find 7a (android phone):
-because of onboard dac chip inside oppo find7a, it just sounds ok
-low, i found it really flat, no to pronounced
-mid, a bit blurry
-high, a bit harsh
-sound stage felt intimate
 
pm3 combo with mojo, (iphone 5, oppo find7a) now, thats what magic happened :
pm3 become really really alive,
-low, wow, controlled, you can feel the punch impact, thumping effect (not basshead type of bass)
-mid, wow, u can hear the singer really breathe the air, swallowed their sulliva :), vocals just really alive and great
-high, superbs, the detail retrieval really greats, so smooth
-soundstage felt a bit wider and had a great sense of 3d depth like
-blacker background, clean
 
so, its really worth it (combo with mojo)
nice job Chord
