But that is exactly what I am saying. I listened to my Yamaha for YEARS in my home with MY speakers and then swapped it out for a Rotel. Using the same source and same speakers, The sonic difference, right out of the gate was quite apparent.
Fair enough, but as you admitted you were offering your own opinions, not facts. That's one reason why I only read reviews to see measurement data and ignore the reviewers subjective description of their perceived sound quality. For me, accuracy (response, distortions, noise etc) is important as one can do their own thing to tune the SQ to their liking.
Based on my experience (I understand yours are different), higher end Rotel, Anthem, Yamaha, D&M products will not likely be the bottleneck in most people's music/ht systems if used well withing their power output limits. Again, we all have our preference, and I prefer neutral sound that could approach what I hear in live unamplified concerts.
