Don't get me wrong, the Shure is fantastic and has loads of features... most of which the average user won't use. It's integration with wireless workbench is fantastic and of course on the larger unit, the Dante feature is ridiculously good. When it gets down to it though, for a simple transmission of audio, the quality is indistinguishable. The only real world experience of where the Shure whooped the Sony was when I was Battersea Evolution. The Shure unit got over 100m from the stage and was still going whilst the Sony managed maybe 40 or 50 at a push. As you can see, err... really useful for those times you have to get that far away from the stage (eg never!)
Thanks for the comments on the showreel, glad you like it. It was a blast to make. Currently editing the next video, which is a monster but nothing like the scale of the campervan video!
