no, panning doesn't mean more stereo. especially if it's the same sound
If you use 3 layers of the SAME supersaw, and pan one hard left, other hard right and leave one centered you are not getting a wider sound at all. All you do is make them louder.
i don't have ability nor luxury to perceive stereo, but after reading some, i understood that short delay and stereo imagers are wonderful for these cases
"There are many ways to achieve a wider sounding mix. One of our favourite ways of getting a sound to fill out a wider portion of the stereo field is by using a stereo delay (not a good idea on the mix bus but it works well on individual sounds).
To do this, pick a stereo delay that lets you control the delay times of both the left and right channels individually. The idea is to set the delay time between the two channels at very small intervals, typically we will go with something like 5ms on the left channel and 8ms on the right. The effect works really great on backing vocals and guitars." - Televisor
