Comparing sound of cables v. wireless

I'm asking about the quality of sound of wireless speaker connections compared to more typical cabled connections. I have a 2-channel mid-fi system (Adcom, ADS) in which I use Home Depot 14 gauge speaker cable. I may or may not upgrade the components in the future. I'm remodeling and can do some in-wall (actually, in-crawl space) wiring, but someone made the suggestion that I go wireless (a transmitter at my amp and receivers at my speakers). All equipment will be in the same room. Does anyone have any experiences or thoughts to share about how the two connections might compare? Thanks in advance.
