A:Answer Hi DonWan13, You can connect any speaker as long as it has a nominal impedance of 6 ohms to 16 ohms. And to get most out the features of this receiver, I'd recommend getting our latest TV models which are the 800H, 950H, and A8H models. And for the Bluray player, I'd suggest looking at the UBP-X800M2, UBP-X800, and UBP-X700 models. -Sam
