Summary: starting from scratch I purchased the Denon as part of a surround system. starting with a Samsung SMART TV, 2 JBL speakers, sub woofer. center speaker and r-speakers on order. PROS: good looking and good quality. great sound, good HD FM CONS: i am NOT an audio engineer, but have had my share of surround systems. The Denon is very technical. the initial hookup was easy enough but the programming was very difficult for me.
