Okay, I used the Audyssey that came with the Marantz and it measure distance levels and you could do calibrations from multple positions. Okay, it sounded very good.
However, I have also set it from one listening postion later with an SPL meter so that the sound level from the listening position was equal and I liked the sound a lot better tahn the Audyssey setting; maybe it was just me ?
I am sorry if i gave bad advice about intechangeable mikes.
However, the reason I said what I said was because I used the Marantz Audyssey mike to setup my older Pioneer Elite AVR in the media room and at least for that intercahnge of mikes it worked very well. Sorry, I made a general empirical assumption.
Take care,
