Your post suggests a lack of experience conducting good listening tests. If you compare electronic gear you need to ensure they are volume-matched. A slight volume difference can be interpreted as a quality difference. In order to ensure parity, you have to level match otherwise you are hearing level mismatches which means your comparison is actually a non-comparison.
When comparing gear, you need to ensure the switching is done quickly. Human auditory memory is fleeting - it can last a second or two. Comparing one piece of gear, getting up and changing the component, then sitting down again is just not good enough. By the time you sit down again you've just introduced a number of variables that could affect the sound that may have nothing to do with any equipment changes.
Getting up and sitting back down, but in a different position can result in comb-filtering changes, and comb-filtering can affect what you hear. Switching between audio gear casually, like 99.9% of people do, you could misremember subtle details that you thought you heard, and your auditory focusing may change at any given moment in time, giving you the mistaken impression that you heard more detail, more 'air' etc, when you just paid more attention to the music at that moment in time!
You need to control how quickly you switch components, you need to level match components and you need to ensure the test is blinded - the idea is to ensure complete parity so that both components are operating in a condition that is apples to apples. You seem to prefer apples to oranges comparisons, so more power to you.
Human hearing is incredibly plastic - it can be steered and influenced without effort. Sighted bias and expectation bias can result in random differences even if nothing physical had changed in the evaluation process. I have personally lost count how many people I have witnessed hearing differences between audio gear when no switching had been made!
Sight allows the fiction of sensitive perception even when nothing had changed. It is not a failing to admit that we are highly suggestible creatures, and it is impossible to use your ears, and completely detach your other senses from influencing what you hear. Bias is innate, you can't turn it off like a light switch, you can only try to mitigate its influence.
And please, do some actual research before deciding to post.
Not possible. I see a post reflecting a closed mind, and now it appears your biases have steered you into thinking that your senses are infallible.
Unfortunately being biased does not mean you are consciously aware of it - you may very well be unaware of its influence on you.
Ever heard of sighted bias? Go look up the McGurk Effect. Oh wait, here is a video :

How are you able to detach your hearing from your other senses? Please explain the mechanism you use in order to achieve this.
If only people used just their ears to listen. Unfortunately people use their ears and their brains, and the brain is where all the fun stuff happens! If you want to sell equipment to your client then a sighted test is the correct approach (well, it's the only approach you can use
), however unreliable it may be. Any other approach would negatively affect your bottom line.
