Dac hookup....


Will there be any audible sound difference between a wireless DAC connection vs. a DAC connected by ethernet?

I like the mcgal comment, same practice here. I hard wire everything, only thing wifi around here are phones and the wife’s laptop. It is dependent on your router, no doubt, but think about that person who games online with a wireless controller. Wireless will always have a lag compared to wired...*grinz
For the best steaming results, you should ALWAYS use an Ethernet  wired connection.  I also suggest you check your modem and router to ensure they are working okay.   Several years ago, I discovered my router was dropping packets especially when streaming Tidal.   
Just remember that microwave ovens at 2.4ghz, and its harmonics, with a dirty diode or cap will play havoc and generate noise.I often pick up noise from which neighbor..i cant say.
is there a maximum distance for ethernet cable, before wireless is preferable? I know in many home the streamer may be 30+ feet away from router/modem

If you are an apartment dweller network interference is a big deal. Use an app like Wi Fi Analyzer to ensure your router is on an unused channel.
