This is a view of my 7.2.6 theater system.  I have been working on it for many years.  I use the room for 2 channel music streaming Amazon Music HiRes through the Marantz Heos system up to 24 bit 192khz along with watching movies through the Oppo and streaming.  I just upgraded my Parasound Halo A-21 to a Bryston 14B3 beast that is putting out 680 WPC into 8 ohms according to the Bryston tech sheet included with the new amp.
