After upgrading, there is no comparison. I have full, rich bass from my towers, something the 367 literally couldn't produce. My r28fs sucked the amp dry. I never had issues with distortion though. Upgrading will give you a much clearer sound. Audessey room processing really changed the way I enjoy music and movies now that I have surround. The Yamaha would make a great receiver for a couple bookshelf speakers in the garage, but if you're spending that much on your speakers, skip the center and go for something that will let you enjoy your investment. Get the center later. Something new will also pass through 4k signals which the 367 doesnt. Just my .02 Sent from my SM-G920V using Tapatalk
