Obviously they don't agree with you since they use Audyssey.
The point is, just because Room-Perfect "works better" for you personally doesn't mean it works better for anyone else.
Do you have any Room-Perfect graphs (either from you or anyone else) that show a better frequency response graph than Audyssey XT32 or Pro?
Perhaps Room-Perfect boosts the bass by 3-6dB and boost the Treble by 3-6dB? Perhaps that sounds great to you, but not necessarily to others. How do we know unless we see the graphs?
You can see from the one graph I posted of Audyssey DEQ. As opposed to the flatter frequency response of Audyssey, DEQ boosts the bass a little and also boosts the treble a little. Although the treble still looked flat on the graph, it was higher than the Audyssey curve, which had the treble gradually tapering downward.
I don't care that much about graphs, as blasphemous as that sounds on this forum
I am not at all dismissing graphs and the scientific process, but it is far from the final arbiter in this hobby.
I recently had a whole bunch of trees trimmed. The crew pulled a large wood chipper truck in my driveway, and starting grinding away. A tremendous racket as everyone knows.
About 30 feet behind the truck, a worker was using a metal rake to gather small twigs. As I listened, it seemed quite likely that while my ears and brain could make out that faint scraping sound against the cacophony of the chipper, a frequency response chart would not reveal this distinction. In fact, a graph cannot tell you if you're listening to a wood chipper or The Beatles.
Charts and graphs and numbers have their place, but to me do not capture the spectrum of what constitutes an auditory experience.
What I can tell you is I've spent years with Audysey, including xt32 Pro (Denon AVP A1, Denon 4311, Integra 80.3, and Marantz 8801). I had little expectation that the 151, which my dealer provided for a week evaluation, would be that much different than the 8801. But that was not the case. RP provided a significant advantage. It has much more horsepower than Audyssey (dedicated processors for each channel), works at a higher sample rate, and provides custom curves for different source material. Low frequencies are more articulated and balanced, high frequencies are clearer, so the soundstage becomes more articulated.
It's quite possible that Trinnov or Dirac are even better, but I've not had a chance to listen in home.
Your ears are the most valuable aspect to the experience. I'm sure both Room Perfect and Audyssey have their limits and faults, but when you consider the myriad of different rooms, playback equipment, test equipment, inexperienced skill sets, and hearing differences, preference is as valuable, if not more so, than reference.
It is in just about everything else in life, so this hobby is not immune from that. Unless there was a mic connected post-brain processing, it is not the complete picture IMO.
