I went from the M80 to the LFR1100. I think that you did hit the nail directly on the head when you say the LFR's make you feel like you are part of the recording.
The only other time I have felt that was with a rather expensive set of B&W speakers set up at an audio expo in Toronto some 15 years back.
Your take on Cowboy Junkies was poetic and directly to the point. I would say however that for me, it's her rendition of Sweet Jane that brings the goosebumps down my back.
