Hi, I currently own an Onkyo TX-SR577 av receiver. I finally looking to upgrade my speaker package from a Tannoy FX 5.1. I'm mainly looking at the Q Acoustics 2000i 5.1 pack for about £530.00. However, I have also seen the Tannoy HTS101 pack for £325.00, which seems like a bargain. So my two question are: 1) Between the two speaker packages would I notice much difference for the additional £205.00, if I opted for the Q Acoustics? 2) Will my receiver be powerfull enough to get the best out of either of these packages (More so the Q Acoustics) or will I need to upgrade? Many thanks
