If you listen to some members you can know how everything works in every home as long as it has good measurements, LOL. These "scientific" members will flat out tell you that how something actually sounds or looks on the screen is irrelevant because that is too "subjective". Can you imagine how they explain that to their spouse?
"But it has good measurements, don't worry"
Bottom line- the system has to look and sound good, but it won't look or sound the same to everyone.
Specs are a baseline, wild claims are from marketing and those two worlds don't usually intersect, other than at the point where the equipment exists, but only by chance.
Why not have a listening party with your nifty noise eliminator and have someone who's not interested or involved in any other way connect it, disconnect it or leave it as-is, randomly and not say anything about it, in a place where nobody can see them? The changeover needs to be very fast, though. Nothing can be said about it, other than "Make notes about whether you hear a difference and describe the difference". Nothing else. Any comments about what will/might be heard can and will influence the results, so they must be avoided. You can't be unbiased, so you should remain uninvolved in the test.
Give it a shot. What do you have to lose?
