Glad you are enjoying your new system TDIPablo. I am impressed to learn the EP175 is able to fill that large of a space. As I said yesterday in my M5 post, the M22's with a sub are one heck of a good speaker. I've been loving mine for the past 7 years.
While you are in your audition window, I do suggest you look at a vertical center if it can physically work in your space. I switched from a VP150 to an M2 and for me in my space it was a nice improvement - and cheaper too!
Feel free to PM me if you want more info
Cheers,
