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

So I finally got around to testing out my new 4 foot Meenova micro usb to lightning cable. Works fine. Feels well made. I like the lack of a lightning adapter. The longer cable means I can keep my phone in the front pocket of jeans and leave the Mojo in my inside jacket pocket. Also not getting interference when I place the iPhone and mojo close together - wonder if that was caused by the adapter.

When I'm using the Mojo as a dedicated DAC (either OSX or Windows 10), the sample rate indicator color ball is illuminated red, even for high-res music. Is there a setting I need to make when using the Mojo as a DAC? Is that when I should put the Mojo into line level mode?

On Windows 10:
- Go into your System tray and Right Click your Speaker Icon.
-  Left click Playback Devices
- Look for Digital Output that says "Chord Async USB" (if you are using USB connection) and click on it, then properties
- Click Advanced Tab
- Try all the different Frequency levels and you will see the power indicator change colors (when you click test).
- The power ball should be illuminated to the color/output you set the O/S to.
 
* Which begs the question... if I set to 24/192.... does the Mojo upscale my 16/44 to 24/192? (I'm sure this is in Post #3 right...?)

You are always using the Mojo as a DAC, nothing is bypassed in 'line level mode' it's just a volume preset that isn't remembered when you turn it off.

As noted above, set the sampling rate in Windows to the same as your music file. However, if you have a mix of music this will get tedious very fast. The solution is to use playback software that automatically sends the correct sampling rate to the DAC based on the sampling rate of the music file. For OSX I use Audirvana+, I don't use Windows for music playback but I know others can help you with a recommendation.

If you just check the box, it will allow 24bit 192khz files to be processed my Mojo. If you change the default sampling rate to 192khz (which you don't wanna do btw) windows will upsample to 192khz before sending the compromised data to Mojo which then upsamples to 32bit 768khz.

The data is no longer bitperfect. This has a negative effect with regards to transient timing. IME, this is completely true and my own listening tests back this up.

Use a bit-perfect output mode in your player. I'd recommend ASIO, but you can also go with WASAPI or KS.

I thought Chord DACs upsample thousands of times via the WTA tap filters and whatnot, not just up to 768 kHz.

My Sample Rate only goes up to 96Khz.

...but I can go higher in my OS settings.

So.... not quite sure what I should be setting then... as this is my HP Spectre X2 Tablet that the Mojo will normally be residing with.

Hi Mojo users...I want a phone to pair with mojo. I used samsung S3 but it often broke up (I believe the samsung UI can be problematic too). Now I want something that just works for the mojo via usb using UAPP. What is the cheapest phone I can get away with that will do it. Even s/h will do. but I want to pay least possible money.  Any ideas? tnx

Motorola G4 is cheap and fast also works very well and smoothly with UAAP running android 7

Just keep OS settings at 16 bit 44khz CD quality. Everything else looks fine.

How would the Mojo pair with Audeze isine 20 iems, Earsonics SEM9 iems, Audeze EL8 Closed headphones, and Mr.  Speakers Aeon headphones?  how would it pair with my current Shure SE846 and my V-Moda M100 hardwired?  I am slowly going to upgrade my gear, but first I would like a little insight on those pairings to see if the Mojo would be good for me or not?  I will be using it out of my laptop and desktop computers and possibly a future dap or two.  I Have a Fiio X5 1st gen currently as my only dap.  I plan on getting an Opus 1 and maybe an Onkyo DPX1A or Fiio X5 3 as well eventually.  My music is all various mp3.  I try to keep it at a minimum of 128 bit rate, but a few songs are indeed below that.  I am trying to stick with 320 bit rate as much as possible now.  I have probably close to or over 250 gigs of music.  I like to have all of it with me and a lot of my old cds were stolen a long time ago so I don't have a way to rerip them at a higher quality unless I rebuy all of those albums which is too expensive for me to do right now.  I would rather spend a little on gear instead of rehashing my past to buy all of those albums again.  I also would like a fairly portable device that doesn't take up a lot of desk space or space in my luggage when I travel.  I got a new computer and it takes up at least half of my desk roughly.  I can't really afford a Hugo or anything.  Something with a small foot print would be much better for me.
 
Thank you

Riley, I think in this situation it would be best for you to find one to demo and take all your headphones and iems with you and have a long listen/ comparison.

Thanks Deftone. This looks a good phone but I was hoping for something much cheaper maybe something old from the last couple of years that paired well with the mojo in the past and is now on the s/h market.   Although I see that the G4 PLAY isn't a bad price but it seem very cut back from the standard G4.

Ah I see, I'm not sure an older android phone would be that much of a good idea. For example the galaxy s4 mini I had lying around had problems with UAPP and OTG cables, also the SD card slot in it had max 64gb support but could not recognise my sandisk 200gb extreme at all. The only other phone I know that definiely does work is a Motorola E Gen phone but that's still around £90

I wish I could.  I live in Northern California way North of the bay in the valley.  I have nowhere to actually try this quality of gear near me.  There is one Best buy in my area and that is the about it audio store wise unless you count Target and Wal Mart.  The closest Apple store is about 2 hours or so away.  I am a farmer and don't really have a lot of extra time and money to travel long distances to shop for audio gear.  It is much easier for me to ask on here and than see different opinions and figure out what is best for me.  However I am going to San Francisco for a concert next month.  Is the Mojo available anywhere in the city itself?  I will be in Reno the next day if there is a place there i could test one please share.
 
Cheers
