No_money, you're missing the point. The important thing is not "don't listen," but "know how to listen." Understand what makes a difference in sound and what doesn't. Make direct listening comparisons, preferably properly set-up double-blind or AB-X. Understand that a listening test is not a test of your hearing, but of the sound of the equipment. Therefore, "finding" differences that don't exist is no more valid than ignoring differences that do. Understand the principals of psychoacoustics so you can better know your own conscious or subconscious listening biases and how to minimize them. The more you understand about the workings of audio, the easier it will be to make your system sound better by investing in what works and avoiding pouring money into what doesn't.
