PWD technical question

I’m thinking of getting one of the Empirical Audio Short Block USB filters. I’m told that it will not work if the Dac needs the 5volt in the cable… Does anyone know if the PWD MKII needs it, or is anyone using a Short Block on their USB input? Thanks!

Yes I am works fine, I love it with my Transparent Premium, sounds more analogue to me than Bridge.

Thanks… Will give it a try then!
