Funny thing...we've had our towers cranked and you couldn't really tell it was stupid loud until you tried to talk to the person beside you or you left the room and came back after a short time. It has to be a decent recording though, crappy recordings, well enough said...
Try an app on your cell phone. It'll confirm a) the actual volume. b) your actual listening preference for the volume and c) which speaker you like best at THAT volume.
I wouldn't worry about distance to your ear causing damage with either of those but the volume will ruin your hearing over time (if it is in fact too loud).
I would expect distance to matter much more with the M5 because of the extra driver. I'd assume a minimum of 6' distance to sound their best.
