| Review summary | The Denon AVR-3808CI AV receiver is absolutely packed with functionality and sounds great, but you'll need to be an AV geek to unlock all its potential. | Info unavailable | Info unavailable | The Onkyo TX-SR606 offers tons of functionality for the price, but subpar video processing and improved competition means it's less of a standout receiver than last year's version. | Info unavailable |
