I recently purchased the in-wall M22's and the on-wall VP100 along with the QS8's and EP175, replacing an M50, M3 system. The M22's are fantastic and the whole system is awesome. I was advised by this board to go with VP150 and EP350 and while I'm sure they would make a difference, especially the bigger sub, it wasnt in the budget. I am using a refurb Denon 1712 and this system is very loud, open and very clean and I am very happy and certainly don't feel like I'm missing anything. Also they look great, nice clean contemporary installation.
