BBIBH, Thank you for your reply. You understand my case very well. I agree with your suggestion so I am going to buy the M3Ti now. Hope that is a set of speakers good enough for musical listening.

By refering to the "Epic Master Home Theater System", I will probably choose QS4 as surrounds but EP125 as subwoofer. Regarding the center, I am not sure if I will go for VP100 or VP50. Anyway, I can leave this question until I start to build the HT later this year.

Thanks a lot for your advice.
