That is interesting...
We use an ORTF mic setup. That means that the right and left channels have dynamic and timing differences (dynamic because they are oriented in different directions and timing because they are spaced apart). This setup is very good for building stereo image, but "supposed" to be not so good when played in mono.
"In theory", if you are going to record something that is going to be played in stereo and mono, you "should" use a coincidental technique. One with both mics on the same axis so that the stereo image will be created only by dynamic differences (no timing differences).
If you play both channels through one single speaker the dynamic differences disappear and only the timing differences remain. So a mono reproduction of a recording made with a coincidental technique will sound almost as if it had been recorded using just one mic while a mono reproduction of a recording made with ORTF will still have this timing differences which are supposed to be not advisable (again, that is: not advisable "in theory")
What I think might be happening here is that a coincidental technique in mono just sounds dull, while ORTF, despite of not being theoretically proper, will still have that extra timing info that far from being "wrong" makes it "interesting" (we could say it adds a bit of a choir effect to the attacks)
Maybe the fact that the recording is very clean to begin with also helps alleviate the negative effects that to much timing info could produce during the mono playback.
