I would much prefer "I can see testing." Live with something for about a day, week, month and notice if you will be surprised by details and nuances that you never heard before. Double blind is stupid. You run it on a system you are not familiar with... with music you are not familiar with.. in a room you have no idea how things should sound... with recordings you have not heard a million times. Detecting differences on short runs of music to be evaluated by men in white coats is not conducive for one to relax and enjoy the music. Its a test is like running an obstacle course.
What ever thing you are going to evaluate? Put it in your system and listen to it for a couple of weeks and listen to many different songs. For the music picked for the blind test might not show the contrasts that with another song the attribute change becomes obvious.
If you are a big boy and can hear? Why go blind to see the light? Its stupid. I used to run AB testing with amps and speakers when I sold audio. Its a pressure test. Not a pleasure test.
If you can't hear when there is an improvement with your own system over time? Then you leave it alone. But, stop treating those who do benefit as if they were mice in a lab. Its inane when on your own system it will either be heard, or not. Its that simple. Some won't. So they want to test others to prove that they are not missing something. Its their way of getting back for what they lack.
