Interesting test, but this kind of music will likely yield more no than yes. I found the sound quality of the test to be no better than that from FM radio so the format is not the bottleneck, the sound quality of the original recording is. He could make it 72 bit 768 MHz, it would matter a bit, FM quality will remain FM quality.
Case in point, I have bought quite a few Flac files from HD track and among them, some CD quality ones sound clearly better than a couple of 24/192 ones. For example, the 24/192 Carly Simon one sounds just a little better than MP3.
