What is wrong with the system or what did I do wrong?
First listens with HE400i/JDS Labs Atom stack, and voices sound like there is a huge hole/recessed/bad connection/faint, along with sibilance. The rest sounds really amazing - bass, detail, imaging, air, high instruments, etc. HE400i plugged into the laptop headphone jack confirms something terrible is going on with the mids using the stack. But why would it only really affect the voices/mids mostly? All I know is one or both of the units are defective. It sounds the same with low and high gain. Computer volume was nearly all the way up. Cable connections are all firm and correct.
