Summary: As luck would have it, my basis for comparison is the similarly priced Yamaha RX-A830 7.2-Channel Network AVENTAGE Home Theater Receiver , perhaps one of my favorite receivers built. For reference, I tested both receivers using the same speakers in the same room with the same audio sources. Out of the box, the Onkyo is a heavy monster, weighing in nearly ten pounds higher than the Yamaha.
Summary: This Onkyo is a hulking beast of an AVR. It's big, black and bulky -- at least 1/3 larger than my Denon AVR-1913 due to its 3 zone capacity and maybe some other internal components. My previous Onkyo was a non-networked Onkyo TX-SR606 7.1 Channel Home Theater Receiver that served me well for several years. It was reliable and simple to operate. Judging from the numbering scheme, the 828 is two generations later, with updated features, ports, and networking standards.
Summary: Excellent sound/features. However Onkyo's implementation of the Audessy features limits access to Audessy Dynamic Volume and DSX with my Definitive Technology Mythos SSA-50 sound bar. DF recommends that auto-speaker setup tools, such as Audessy EQ, not be implementer its Mythos SSA-50 sound bar.
Pros: Great sound and features
Cons: Implementation of Audessy features and lack of backlit remote.
Summary: This Receiver replace an older model Onkyo receiver that gave its life to enterainment pursuits, IE my kids were always forgetting to turn it off. I am very happy with the new one easy setup and great sound I have it hooked up ot Polk Audio's speakers and using a Velodyne sub
Summary: Pour le moment cet appareil me donne entière satisfaction. Les réglages ne sont pas toujours évidents mais bon avec les nouvelles technologies, rien n'est facile quand on est de la génération des appareils à gros boutons frontaux.
