...And here I thought I was decided on silver. That black is hawt.
I have tried two DAPs (Shanling M1 and Hidizs AP60 as USB transports) and some apps with the Mojo and here is my findings about them. Any comments will be very welcomed!

P.S.: BTW I've got the best sound from the Mojo with an Audiolab 8200CD/V12 outputting optical Toslink stream to the optical input in the Mojo.
My Mojo whines when charged from the Schiit Wyrd and iFi iPower 9V power supply, but is silent when charged from my laptop.
Not sure if it would charge faster from the Wyrd, but it seems like the whining can't do it any good, and it would be a shame if it damaged it somehow.
That has been my issue from the beginning. The replacement is a bit quieter, but...I guess it is a common thing here and Chord seems to think it is "OK".
Do you get any noise when charging from a laptop? (I don't.)
I also noticed the Mojo charge light going on and off from the Wyrd, so I get the feeling I shouldn't charge it from that.

If the light is going on/off then you aren't charging the Mojo properly. A blinking charge indicator light shows you aren't supplying the minimum 1A current to the Mojo.
The light cycling on and off, sounds like the wyrd power supply is not supplying 1 amp, so the mojo keeps going through a cycle of:It is explained in post 3 I think
- start charging and check if 1 amp
If not 1 amp then stop charging
Wait a few seconds then restart charging and check ampage again
Etc

I kind of just assumed the Wyrd and iFi iPower 9V power supply would supply (lol) more than my laptop would, but perhaps not.
What do you think causes the louder whine here?
In any case, I'm just fine with continuing to charge it from my laptop as I always do.
Actually, even charging from the laptop, there's a small whine, but I can only barely hear it when I put my ear right against the Mojo; otherwise it's not audible.

Don't worry about it if you hear the noise, Mojo is not faulty and will continue to be reliable.

I thought the Wyrd was all about cleaner power, so why would it do this?
Could the cause instead be the iFi iPower 9V power supply?
