Quick question guys,
 
Will  http://a.co/6lwjLHq [Mediabridge RCA Right Angle Adapter - 90° Female to Male Gold-Plated Connector - 2 Pack] work for digital signal without degrading sound?
 
The mediabridge website says this: 
 
 Impedance 75Ohms

So I guess it's okay? (I'm confused because the ohms in RCA is supposed to have to do with RF interference right?)

  WEIRD! maybe i'm tripping out, idk. Oh well. But then there's this post:
 
Just tested it (again, there's no REAL way to tell if the battery is being used or not other than to just keep it running for a bit to see if battery is drained) and it works. @iFi audio  can you confirm this?

 
Please turn it ON before USB connection. This 100% means battery power instead of USB power!

  This is exactly my experience, when USB is plugged, you cannot play from coaxial. it sure will charge but will not play.

 
1. USB audio+power supplied (eg from PC) then SPDIF becomes output
2. USB power ONLY supplied (eg from USB charger) then SPDIF becomes input
 
That is it really. If there's a struggle still, just open an STS ticket here: http://support.ifi-audio.com

Oh ok thanks. NOt sure why others here are having issues with charging + coaxial though.

Hi, iPhone 5s 64gb as dedicated transport for the ifi micro idsd black?
Good idea?
I have a 6s but is filled with pictures and apps, I was thinking about getting an old 5s and use the usb dongle to ifi.
Besides only being 64gb, anything wrong with going that way?
Specially now with ios10 I can remove all Apple apps that would give me more room.
Thanks!

Silly question that I probably already know the answer to but I need reassurance. If I get a Sony Walkman and connect it via USB to my Micro IDSD, I'll get the same sound quality as when I do the same with my MacBook, correct?

I thought I am the only one who has this problem, I then search the whole thread and found several posts mentioned the same problem. I have "two" iDSDs, one silver and on BL. Both have the same problem. It seems like only older firmware 4.0.6 supports what iFi audio says. I think I'll return my iDSDs. It is rather disappointing.
 
How many people are able to play from "Coaxial" input while connected to a usb charger?

I had the same question, in post #4664 on page 311, and never received an answer.

My only "solution" thus far is to use a powered USB hub with individual switches for each port. Whenever I use the iDSD's optical input, I make sure the hub's port that's connected to the iDSD is switched off. This way, at least I don't have to be be connecting and unconnecting the USB cable all the time.

After  an extensive back and forth with IFIs technical support they suggested I try different versions of firmware, and finally  an older version 4.06 solved the problem .... Make sure you wait for like for 5 seconds for signal from optical input to come on.... The instructions are there on their support page as are several firmware versions.... Hope this helps!

Ok, I tried to upgrade to the newest firmware 5.2b and now it charges and takes coaxial input. Sorry for all the troubles.
