I do think after an audiophile has a speaker, amp, front end, and room acoustics picked, the audiophile can then make or break those choices with cables, fuses, and A/C outlets.
David, I totally agree with you on this point. I have tried a few different fuses and outlets, and many, many, many cables and cords over the past few years/decades. After decades of trying different cables/cords, I am of the mindset that ANY gear can be made to sound good or bad depending on the cables/cords used with the gear.
I have heard cables sound terrible with some gear, sound fabulous with other gear. I have heard some gear sound terrible with some cables, and fabulous with other cables.
It's all about system synergy and personal tastes, IMHO. I feel so strong about this, that I don't know that I agree with this statement of yours:
I have tried to report what I have heard as so not everyone will have to repeat the experiment.
While a noble sentiment, I don't know that there is any substitute for personal trial and error. What sounds good to me may not sound good to you, and vice versa. Also, since we are probably using different gear, I tend not to take anyone's opinion as something that will prevent me from running my own "experiments".
I have owned too many highly praised items over the years that did not work in my system to think that anyone can perform an experiment that will save me from having to repeat the experiment.
I've also learned that if someone is happy with there current sound to congratulate them. I do not try to stir the pot to continue to feed the disease.
I've been perfectly happy with my system a few times in the last 30+ years. I wished I could have learned to stop and just enjoy the music.
It seems every time I'm "perfectly happy" I get bored after a year or so and try to "better" my system by trying some great new XYZ that the Net and/or Mags rave about, only to screw up my perfectly tuned in sound.
Then it takes me a year or two to dial the sound into where I am happy again, but the cycle will repeat itself.
Sigh.....like a dog chasing his tail, this is what we do for fun.
