Thanks very much for the suggestion. I bought a Khanka case off Amazon for $12 a month or two ago and have been pleased with it. It is a hard fabric case. The micro iDSD fits nicely in one half, secured by an elastic strap, and there is room for cables and connectors in the other half. In case anyone is interested, here is the product link:

But that Waterford Gear Pouch looks interesting and may have a little more room. I'll probably pick up one of those as well. Thank you. 


Can you post a picture with the iDSD in the case?


A full day at work concluding with computer problems yesterday, so just now getting a chance to post some photos of the iDSD in the Khanka case.

How will you connect the phone via OTG to the iDSD and at the same time connect it to the hub?

Does the phone have more than one USB port?

The OTG cable you showed won't do it. The cable from the hub would only power the iDSD, not the phone.


I don't want to power the phone, just the iDSD... but still send the digital signal from the phone to the DAC...
ANyway, I think I'll just buy those and try.
Worse that could happen is that it doesn't work... :frowning2:

The OTG cable you showed should work fine but I don't see why you need the hub - unless you want a hub for other purposes.

You could just use a USB power supply. If you didn't mind spending a little more, the best power supply would be the iFi Audio iPower 5V.

I have the "B" firmware installed so micro doesn't go to sleep mode and doesn't steel from my phone's battery. All is well.
But when I turn the micro off , I see that little blue light, which if I'm not mistaken means he is stealing again!
Is there a workaround for this? It's so annoying to detach the cable or turn the phone off every time.

If your iDSD micro is attached to computer via USB and turned off, I believe the blue light indicates it is charging off of bus power.

This looks good. Thanks for posting.

Yes. And it draws charge from the phone as well when it's connected via the OTG cable and it's turned off.

  Hi! Can I connect the IFI IDSD Micro to the AR-M2 player ( in order to amplify it)? 
 
Thanks
Roi

 
HI,
 
AR-M2 (or any audio device with 3.5mm out) connect it to the 3,5mm input of the micro iDSD.

Hi, thank you! Can the  IFI Micro IDSD be connected to a computer\laptop via USB and be used as a DAC?
 
Is the IFI IDSD the best option for a portable AMP\DAC?
 
Thanks a lot!

I have an annoying problem with the iDSD. I have it connected directly to my Mac USB and only turn in on when listening. Otherwise, I turn it off and leave it plugged into the USB port. However, when it is turned off and my Mac goes to sleep mode, the iDSD will not connect when I wake the Mac up and turn the iDSD on. Once this happens no amount of turning on/off the iDSD will connect and show up as an audio device. I found I have to physically disconnect the USB cable while the iDSD is still on and plug the USB cable back in. Only then it will be recognized. I suppose I could just leave the iDSD on, but if there is a simple solution to this I would be grateful to know. Neither my CDM, Mojo, or DFR have the same problem.

  Has anyone used the iDSD with Daphile, and in particular, Daphile DSD256 and DSD512 upsampling? Are there any differences in sound from PCM? Also, what CPU are you using and what is the loading like?

 
Not sure about Daphile, but Foobar:
 

 
 
Difference - it's a completely different DAC, half of which is in the software. It's a sigma-delta pre-rendering in the phase where clock jitter cannot affect it, not just upsampling. Whether you will like it depends on your personal tastes. For me now PCM is a no no (unless mobile or backward compatibility).
 
For DSD512, make sure you have a recent mainboard with a good USB implementation though (think gaming-mobos).

From afar, it is hard to say what is going on with the mac and iDSD. Could be the Mac keeps the power on the ports but shuts the USB connection down. Then the connection cannot be re-established. 
 
Possible options:
1) Set the Mac to fully shut down, not sleep.
2) Set the Mac to shut down the power to the USB Port when sleeping.
3) Using a hub may also help
