I recommend the Ifi Idefender as it solved my issue. Going full ballanced doesnt ensure you to be free of grounding issue. My problem was noise coming from computer via usb port to the RME to my subwoofer and the RME + Speaker and sub were connected via XLR ballanced. Using Toslking optical...

Hi, Thanks for the feedback, Its a groundloop issue and I had the same problem with another DAC. This fix that you did is not the best solution. It allows you to find that your USB is noisy but is not a durable solution. I had the same Issue on my ADI RME DAC FS and RME strongly recommended...

Hi Everyone. New Feedback and problem solved on my side. I confirm 1rst unit had a problem. The second unit is working perfectly. Customer Service at SCHIIT Audio is very good. No question asked . I returned my unit and they sent me another unit. They also paid for return of the first unit...

Hi sidpost, Thanks, I really wanted it to work (in usb mode) and I have quite some cables/pc/mac etc at home to test. It's electronic equipment so it can happen. I sent back today the unit to Schiit CA. I will report once the SAV process is complete. Best Regards

One of the cable I tried is indeed an Anker micro usb Cable purchased on Amazon. I dont have '' audiophile ''micro usb Cables.

hi gefski , My unit usb connexion is not partially working. Not working at all. Hi Mikem1062, I tested with the 3 micro usb cables i had on hand (including the provided cable) and also on a PC instead of the Mac. It's probably a defective unit because i get no power or light when i connect...

Edit : Problem solved (replacement unit) Hi everyone, Just received my unit and sad to report it just dont work with usb at all using self powered connection and usinq usb adapteur . Tested on Imac and PC ... I probably received a defective unit. Hope Schiit SAV will handle as I'm based in...

Ordered mine today after a listening test at the parisian audio technica store.    I find them to be different and better than the old ad900 and equal or better than the old ad1000 that I tried simultaneously.

I recently did a re-cable on a DT770 Manufaktur: Some pics here: http://blasserre.wordpress.com/2013/03/06/dt-770-re-cable-balanced-mod/
