I've had multiple speakers, from different companies, in my space since enabling XT32 on my Onk. They all sound like garbage without Audyssey. Ditto with my EP600. The room and the speakers form a system whose response is controlled by Audyssey.

It sounds freakin' amazing and that's not just my opinion but the opinion of everyone I've blind-folded and converted to an audiophile. Once they've heard it, they can't go back to the junk they used to call "good enough".

I don't want to listen to the Model T 'cause I'm sure mine would sound like junk in comparison.
