We did some tests a while back comparing a Zaxcom TRX742 and Lectrosonics HM to a cable connection, and to the human ear on studio monitors, none of the people we showed could hear the difference. Even the cheaper Sennheiser gear sounded pretty good - although you do get what you pay for.
It all depends on what microphones you're using, what you're recording to, and WHERE you're recording.
If you're recording device is a Zoom or a BMCC - then seriously, I doubt any professional will be able to HEAR the difference between a DECENT wireless system and a cabled mic.
If you're using the very best microphones and very best recorders in a really good environment for recording, then you might notice a very, very slight edge from cable over wireless even with the very best wireless systems. But in the real world, for people that are working with camera's costing less than $2K - I think it's a bit of a non-issue.
Wireless obviously has lots of other disadvantages compared to simply running an single XLR and plugging it in, but in terms of sheer audio quality - I definitely wouldn't be afraid of using a TRX742 on my boom pole. If I'm using the BMCC as my recorder - I'd probably still be comfortable using a cheap Sennheiser system.
