Over the last two days, I've made small physical changes to my AV room that have resulted in BIG audio gains. I should have made these changes 10 years ago when I acquired my system. I really can't complain anymore about the sound quality which I always knew was due to my room and not my gear.

Nonetheless, I know from listening at Jakewash's place the VP160 blows my VP150v2 away. Given the 12 foot distance to my surrounds, I bet the QS10HPs would be a step up from my QS8v2. How big, I don't know until I try them. As for my EP600v2, I again have no doubt the sealed EP800 would add a dimension I can't imagine.

The only wild card here are the M5HPs against my M80v2. I have it on good authority the M5HPs will be more linear than my M80v2 and the cabinet will be stiffer than the M22Ti (which I have experience with). I suppose I could always buy them and return them if they don't best my M80s.
