Jason, yup my findings were similar. I read your thread and comparison with great interest. Unfortunately a VP180 is just not in the cards for me.
I have been running the M2 for the last week ever since it was delivered, but did not get down to the back to back comparison until last night. There were a lot of subtle differences I did not mention to try and keep my 1st post readable. Specifically I did not bias my wife one way or the other, so I was pleased when we both had very similar opinions on the 2 speakers.
Yes, the i/o M2 is staying so now I have to figure out what to do with the i/o VP150. Drywall repairs and painting will be commencing this weekend. Actually that may motivate me to finish off the trim and closet doors in my HT as well!
