I want to buy new home theater system and I decided to buy center VP-100 and surround QS-2. Before I went to store I decided to go with M50Ti for front. But the guy in store adviced me to go with M40Ti because they sound better. So I little mixed up. How it is possible? I want to buy either Onkyo TX-SR500 (65Wx5) or TX-SR600 (80Wx6).

So I need your advice. Thank you all.
