Add ipod touch gen 6 to system


I'm in the process of adding a w4s dac replacing ancient Audio Alchemy equpment. What is a reasonable setup for using my Ipod touch gen 6 as my music source? I was considering a wadia i170 but they come and go and I'm not sure the gen6 is compatible.

Go read the info at Computeraudiophile.com. According to some of the folks over there, the iPod/iPhone will output bit perfect digital over the USB 3 Camera cable. The USB 3 camera kit cost $40 at Apple. Give it a try, you can't go too far wrong.

My NuForce Icon iDO definitely will output bit perfect digital output. It also has a built-in DAC and can output 2-channel analog line level. 
The W4S dac has an a-b usb input. What I don't know is if the itouch gen6 will send digital output to the dac. Wadia produced a dock that was compatible with the earlier generations but I don't think it is compatible with mine.
@credalter - Does the W4S DAC have a USB input? You may be able to use an  Apple Lightning to USB 3 Camera Adapter. Check the forum over at ComputerAudiophile.com for information. It has been reported to work for many people.

Another alternative is a NuForce Icon iDO. I have one of these and it works great with an older iPod with 30 pin connector, as well as with a newer iPod with Lightning connector. My buddies come over with newer iPhones 8's, 10's and it also works just fine with their phones too.
