There is still a small matter called preference and that varies from individual to individual...Why any engineer would choose lower (perceived) resolution or less than neutral response?
"I take it that you obliquely accept that those parameters are measurable, am I right?" (damn HTML tags not working again)
I will restate my opinion. The numbers alone do not provide any useful information. We have yet to measure RFI noise rejection. That increases noise and thus reduces dynamic range. If you were to compare two amplifiers with necessarily different spectral harmonic distortion plots, which one would you choose simply by looking at the spikes? Such information is more of a curiosity rather than providing any conclusive evidence.
Don't you know that by now? I merely state the obvious.

"Why any engineer would choose lower (perceived) resolution or less than neutral response?"Because the engineer is looking at the whole package, not just a single variable.
"I will restate my opinion. The numbers alone do not provide any useful information. "
I do not recall anyone (of note) claiming so, or do you evidence to the contrary?
> We have yet to measure RFI noise rejection
For amplifiers maybe because it is not particularly relevant, but RFI noise rejection is measureable and quoted on some products where it is a relevant metric.
"That increases noise and thus reduces dynamic range"
????, how could know you possibly know that without measurements or controlled tests. Increased noise and reduced dynamic ranges can occur as a result many other factors, to establish that it is caused by increased RFI requires measurements and controlled tests.
" If you were to compare two amplifiers with necessarily different spectral harmonic distortion plots, which one would you choose simply by looking at the spikes? Such information is more of a curiosity rather than providing any conclusive evidence."
For those that lack knowledge of how to correlate measurements to listening impressions you will be correct. However this scenario is not unique to audio but applicable to every area where measurements are used, and in a lot of cases it is simply down to a lack of knowledge on the side of the observer.
There is no explaining to do, those variables are measureable, however correlating them to listening observations requires some requisite knowledge.

By all means, choose your gear solely on numbers. Good luck!
"By all means, choose your gear solely on numbers. Good luck!"Where did I ever say that, for one the measurements are not always available nor comprehensive enough to be able to make that a viable option. At any rate, you never did answer the question, did you?

At any rate, you never did answer the question, did you?You first. That is what began this exchange.
An impasse....willing to wager that you have absolutely zilch to put on the table, if you said this five posts earlier we could have saved ourselves a lot of pointless posts.

that's exactly what I was thinking about you. What a coincidence! I ask you a question and you have evaded answering it for the following seven posts.Your lack of an answer is an answer. Same one I arrived at as well. :)
I suppose you forget the point at which you joined the conversation, i.e. I said the variables adjustment by Behringer DSP8096 are independently measurable, how else could they write a suite of program to modify them if they were not?Don't bother answering..
I directly quoted the comment to which I responded. Let me help you out....the effects of an equalizer on any given system are independently MEASURABLE.
> I directly quoted the comment to which I responded. Let me help you out.
...the effects of an equalizer on any given system are independently MEASURABLE.I wonder how Behringer managed to write a suite of programs to modify dynamics, imaging and provide dynamic noise-gating if they are not measureable.
What is your next crock?

You're talking about post processing effects and I'm referring to original audio signal integrity. The imaging to which I refer relates to less compromised signal quality, not a "setting" with a slider.
Earlier you said this"> I directly quoted the comment to which I responded. Let me help you out.
...the effects of an equalizer on any given system are independently MEASURABLE."now you said
"You're talking about post processing effects and I'm referring to original audio signal integrity"
What is the else will the effects of an equalizer? and even your new revised statement is still wrong, since you still have to measure the original "uncompromised" signal before making any adjustments.

that despite your assertion, the effects of which cannot be fully measured. Signing out. You get it or you don't.
Obviously you do not get it, because it was and still is about audio quality pre and post-processing. I love your phrase "the effects of which cannot be fully measured", yet another crock, I said measureable, let's just say "fully measured" is a waste time and money, "relevant and applicable" is where the action is. AJinFLA's post is more succinct. he said"...because we really can't measure everything, so we might as well measure nothing and just listen with the trusty ol' ghost hearing measurement devices only, the ears."
it sums up your most of your posts nicely. Signing off
