A standard 10 metre USB cable will not carry the audio signal properly (it will not work well) but by adding the iPurifier 3, it will actively repeat the signal and extend the run. Therefore, by adding 2 x 5 metre USB cable lengths, then it is definitely possible to use the iPurifier 3 in the centre to extend the USB run.
So by adding it to the middle, the chain will look like this: 5m USB cable > iPurifier 3 > 5m USB cable, which results in a 10m USB cable run.
