Download that and put it on your phone. Pick a time slot, there's a few good ones, and record it. I'm happy to do that. It might be a couple days.
I'm really not in any hurry any longer. I put away the mic and everything else. But I don't mind throwing up a video comparing excursion if it helps the community.
My eyes aren't great (with a detached retina years ago followed by Lasik more recently, they're actually not bad for my [middle] age), but I've avoided blindness so far.
And, to give credit where credit is due (and much deserved), the file is from Archaea's subwoofer shootouts, for which there are several (interesting) threads.
