new to this so need help trying to figure out what to purchase. I got suckered into purchasing the Bose soundtouch 300, acusticmass 300, and vi speakers and I was not impressed one bit so I think I'm gonna just try and build my own surround sound.I've been looking at the Onkyo 747, 757, 777. I want power, wifi, Bluetooth, 4K , something that can possibly auto calibrate and the 2 subs since I like a little more thump. I have a budget of 1k but don't wanna go that high if it's not needed.
