Oh good.
Meanwhile I leave the oscilloscope on to deal with the tedious business of 'listening to music', whatever that is -along with ascertaining my pleasure with the hifi.
Lol

The onus isn't on me - it's on you. You expect one to sound better than the other and have stated so. But you've only heard one, not both. Don't project on me please.
I don't thing machines will be able to mimic human behaviour until they get to the point where an accidental fart during a meeting causes them to giggle.

Oh yeah, the topic. Cd 555 and 555ps, sorted.
Ian,
I was at a meeting where one of the senior directors farted accidentally. It was all I could do to not laugh.
Interestingly, it was the CFO who let one slip. To this day I've not been able to picture finance for the F in the title.

That was my thought too, but not sure you can pick one of those up for that sort of money yet though.Oh yeah, the topic. Cd 555 and 555ps, sorted.
Sadly it will require other behavioural requirements several orders of magnitude more complex than giggling when methane is detected.Excellent.
When I make my first robot it will be a girl one.
This avoids tricky fart based humour programming.
So you'd tell them to buy the speaker that they know isn't the one with the best SQ and that they can afford simply because they couldn't prove that in a statistically significant manner in a blind test...
How crazy is that?
It isn't crazy to recommend somebody buy something cheaper when it sounds the same as another dearer one.
What is crazy - bizarre even - is to suggest that somebody knows one has the best SQ even though they can't tell the difference blind.
Truly weird.

Careful! We're creeping into psychoacoustics territory...
The ears+brain work together in strange ways to recreate a "soundstage" - lateral positioning is mainly decoded from relative left-right emphasis while depth is mainly decoded from phase shift detection. Much of this is from a mix of direct and reflected signal. The key is the way in which the brain "decodes" the complex combination of waveforms received by the ears and passed to brain as electrical impulses.
If we accept this explanation of how we perceive a soundstage then any attempt to construct a "machine" that can both detect and measure "soundstaging" is likely to be one monumental exercise. In order to create such a machine, the creator (not capitalised) would need an accurate and detailed understanding of just how this perception is done and I'm not sure that science has enough information and understanding of the ear:brain functioning to enable such a machine to be built.
The other aspect lies in the relative intensity of some of these spatial cues used by the ear:brain to conjure up these perceptions of depth (particularly) as the intensity levels of some of the depth cues is very low in relation to the "musical information". The audio rig needs to have a very low noise floor to enable the listener's ear:brain to detect enough of these cues to re-create the soundstage and if the noise-floor is too high, these cues will be masked and render the soundstage erratic in its presentation (due to music's continual variations in intensity).
Obviously, if we detect depth from phase shift cues, then the audio rig needs to maintain phase accuracy to allow this perception function.
So, what may be a feasible solution - rather than building a machine that can re-create a soudstage and measure it - is to rather build a machine that can detect and measure the various types of spatial cue "enabling" characteristics (e.g. noise floor, phase accuracy, left:right amplitude accuracy, etc.) and, based on whether or not these measurements fall within some yet-to-be-defined limits, to give a mechanical equivalent of a thumbs-up or thumbs-down to the system's potential in this area.
But I'm merely hypothesizing...

You're making the mistake of thinking that not being able to tell the difference blind shows/ proves that it sounds the same.
Leaving aside the fact that I don't agree that that is a mistake, the point I am making is that if 2 speakers are indistinguishable to somebody listening blind they may as well buy the cheaper/smaller/easier to site model since any SQ differences sighted are obviously either imagined (look the big expensive ones sound better) or at least too small a difference to waste money or space on.
Strangely Stereophile actually comment that their A and A+ speakers often have very unusual frequency balances and require careful auditioningLeaving aside the fact that I don't agree that that is a mistake, the point I am making is that if 2 speakers are indistinguishable to somebody listening blind they may as well buy the cheaper/smaller/easier to site model since any SQ differences sighted are obviously either imagined (look the big expensive ones sound better) or at least too small a difference to waste money or space on.
