usb/optical out for fiio D3, and then for an headphones amp

post #1 of 5
Thread Starter 
hi guys

firstly, sorry if this thread isn't belong to here.
this is my near future sound system
PS3 -> Optical out -> Fiio D3 -> O2 amp or Fiio E11 -> Beyer DT990 pro or Ultrasone HFI 580
( I've just ordered the Fiio d3, snd E11 this black friday, they will arrive soon.)

but I want to use this set with my laptop too, however, my laptop doesn't have optical out :-(

so please fill in the blank
laptop usb -> [???] -> Optical out to Fiio D3

I saw something like Turtle Beach Micro ii, Syba usb sound card. Do they work? I don't know much about the optical port, will the sound quality be different in each devices? Or they are the same since it comes out from optical port???

please help

Thanks...

But I've got the Fiio D3 today. It cannot receive Digital Signal through the usb port. It work perfectly with S/PDIF cable though. 
By the way, I've bought this 
http://www.amazon.com/gp/product/B006SF68P2/ref=oh_details_o02_s00_i00

In order to use just it's S/PDIF out for the d3.

 

Thanks again.
