The old. Onkyo Receiver, Bose 6.1 system that's 10 years old, still sounded good and was working well, buy It was out of date. No bluetooth, wifi, usb, etc... In with the New! Yamaha Aventage RX-A840 from a different online retailer. Everything else is from Crutchfield.
Fit & Finish is amazing for this price; Sound is incredibly smooth; Hand built; Great warranty..
Absolutely None!
