Hi, I'm new here. I'm also in a similar situation. I'm currently running an Onkyo TX-SR805 (130w x 7) with Infinity Kappa 7 Series II (89db efficiency) in a 7.1 setup. I might upgrade to the Kappa 9.1 or 8.1 if I ever come across them on CL. I'm tempted to buy the Outlaw 7700 especially since it's on sale. From what I've been reading in this thread, I won't notice much of a difference? If there's not much difference, why would anyone consider getting separates instead of a receiver? Why would anyone buy a 200w x 7 or even the 300w x 7 amp when a receiver at less than half the price of separates produces a similar sound? I don't mind upgrading to separates and a more powerful amplifier if the money I spend will make a difference. I just don't want to spend $2500-3000 if I'm not going to notice a difference. Any thoughts and opinions would be appreciated.
