Even major companies like Denon are using and producing same measurements as me although sadly they are not releasing them to consumers.
OK, let’s take a look at the Sound United "Experience Center" where they test the gear as it is meant to be used, in a proper setup. You have two speakers in an untreated room with a mic and a PC. Your in room FR that looks like the Mississippi river during a hurricane.
You don’t have the proper conditions to even listen to MCH gear much less review it, you know that, please stop, ok?
You have gotten a lot wrong there. Let me start at the top. Every Denon and Marantz review is done with prior consultation with the company. See my last review of Denon AVR-X3800H for example:
And this statement: "I grabbed a preliminary set of measurements from the DAC section of the 3800H and ran it by the company. Within typical margin of error, the measurements were the same as company's own."
So we have the company being fine with my work, but you think something is wrong with my testing?
No, there is nothing wrong. I perform 2-channel testing because a) a lot of people want to use their AV products for music also and b) I use 2-channel systems as the standard that the AV industry needs to strive to match.
Keep in mind that nothing different happens in an AVR because you have 2 speakers or 10. Each is calibrated independent of any other channel. What more than 2 channel does however, is screw up your perception of fidelity. Research shows the more channels in playback system, the less critical listeners get.
The above is the reason behind you screwing up the response of your system completely yet still think it is all fine. You are lost in the spatial qualities of multi-channel, not realizing tonality is screwed up, and bass sucked out of the system. The research behind this is solid as a rock:
