Ben4CansI imagine that all units have the grounding problem and will shock you if you are using a desktop amp but most people are not using this with desktop amps. I tried on my desktop amp and got shocked but on my Pioneer XDR-100R portable DAP, I don't get shocked.
TheocratWell, on reviews they all say it takes power to open it up or sound better. I dont have crazy power off my current DAP but I dont want to play russion roulette on what is shocking and what is ok to use.
