Add ipod touch gen 6 to system

@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.

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.

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.
