It sounds to me quite decent, until attention is paid to the imbalance in sound level between the front and rears (fronts are the EPS 4ohms, rears are the rear/sides in parallel =2ohms). I have not found such an imbalance with any of my 2 PDX installs with the exact same OEM EPS speakers in the same exact configuration.

The one HD-600/4 I came over with was NIB from JL. I did switch the amps (HD-600/4s) and I got the same uneven power output with the 2ohms vs 4ohms!
