Hey everyone, I just started using Sound Gym and I'm running into something weird with the Pan Girl game.

When I play through my MacBook's built-in speakers, I can pick out the panning position pretty easily. But when I switch to my external speakers, everything sounds like it's sitting dead center.

Has anyone else dealt with this? Is it a speaker placement thing, or am I missing something obvious? Any tips would be appreciated.

My speaker setup:
MacBook -(USB)- Fosi ZD3 DAC -(XLR)- Fosi ZA3 Amp - Speakers
