Cable Concealment

I’m going to have my LSiC and LSi7’s closer to the ceiling, when I’m done with my remodel. What would you all suggest as a way to run wire as discreetly as possible?
I live in a rental that doesn’t have the option of going above the ceiling, and I don’t want to take the time/energy of going through the walls, or using a fish (I said fish, haha) to go from point a to b.
Ideas?

@EndersShadow uses them.
Thank you Herm.
Cable raceways in general work great. You can get them from most places online or stores.
I'd recommend using either 12 or 14 gauge speaker wire, specifically in-wall rated kind (it looks good as its circular and easy to lay down).
