If I had reason to believe you were correct regarding 99% of forum readers, but
that I had successfully opened the mind of just 1% of readers, I would feel I was completely successful in my endeavor to promote evidence based science over the huge amount of superstition, myth, and snake oil peddling, I see so often in this forum.
"Open" and "airy" might properly be used in describing a device like a speaker or a microphone, both transducers, due to predominantly frequency response differences, whereas opamps on the otherhand, such as Denon and Marantz ones, have "ruler flat"
frequency responses over the audible bandwidth (not to mention negligible distortion and little noise under most conditions). Because of this, anyone describing the AV7005 as "open and airy due to the opamps it uses
; I can hear that." is
B) errantly applying an expectation bias they have as to "which should sound better" [Gee, more expensive separate preamp over cheaper all-in-one receiver? How surprising.] in their decision making, because their test is not using scientific protocols to preclude human biases
C) falsely attributing a small change in the system's
frequency response which they deem "open and airy" (a perfectly acceptable description, I have no problem with) caused by other
factors, such as different microphone placement during Audyssey room correction calibration runs, (or small, expected, sample to sample variations, even if they glued down
the same microphone to the exact
same room locations for the two calibration runs)
