Last year a friend of mine wanted to venture into the home cinema market and tasked me with finding him the best setup for £500 (Receiver / Speakers / Accessories). I set about scouring the market and concluded second hand was the best bet. We ended up with an Onkyo TX-NR609 and a Q Acoustics 2000i 5.1 Speaker system. I visited him last weekend and was absolutely blown away by how good it sounds. It makes my system sound like I'm listening to a soundtrack underwater by comparison. My setup comprises: Yamaha RX-V379 Receiver Tannoy Mercury F3 Custom Fronts Tannoy Mercury FC Custom Centre Tannoy Mercury F1 Custom Rears Tannoy TS10 Subwoofer My speakers are knocking on the door of ten years old and my receiver oh probably three years old. What's the weak link in my setup? The Amp or the speakers? Would I be better finding myself a TX-NR609, or a Q Acoustics 2000i speaker package? (Yes yes I know, both, but gun to the head one or the other what would you go for?) For note both mine and his receivers are being fed DTS HD or Dolby True HD audio tracks.
