To all - I started this thread to share an experience which greatly surprised me and which I thought might be interesting to some and perhaps encouraging to others. It certainly has generated some interest…
Thank you for the thoughtful and respectful post. Our youngest is pursuing her dual PhDs in Ann Arbor. Fun town but we rarely get to visit as she’s pretty busy as you can imagine.
Just to reiterate a few things - I respect your position as a skeptic. Your original post implied little room for you being open to the idea that there were perceivable differences. But your follow up post clarifies this.
As you note, I did try to remove those elements that might have caused my own cognitive bias. Aware of my own shortcomings here, I try to be somewhat careful with money. However, I will politely reject the notion that I was clouding my bias to to garner social status. Smiling as I write this, I would not spend money on cables to boost my status on Audiogon forums. I belong to no audio clubs. No one but my wife knows what I’ve purchased (brands or amount spent) and all the affirmation I get from her on these purchases is “really? Whatever.” :) Yes, she indulges my fun.
@ossicle2brain The flip switch concept is interesting as a aid in this - I never thought of that. Of course, there would still be a sizable pause between cables as equipment should be shut off to avoid the big pulse. Further, my digital gear reboots after losing power.
I’ll put some thought to a different way to do this. If I could find a way to make a high quality recording, I’d happily post those files to this forum without identifying which is which and let the forum participants weigh in. Unfortunately, I lack high quality recording gear and I don’t think going upstream there is a good spend, but if I can borrow some, I’ll do so.
Lastly, I reinforce the idea that differences in these cables can be successfully measured. I won’t dispute that there is massive subjectivity in what is good, but our ears are relatively sensitive instruments. Why can a power cord make a difference despite all the mileage to the house and the cabling in our walls?
As previously noted, I’m not a materials scientist - nor an electrical engineer but it’s worth noting that electricity does not actually flow through our cables like water through a pipe. Perhaps the best analogy I can come up with is that electricity is more akin to sympathetic resonance across all connections. In this construct, it’s easier to conceptualize why every segment of cable acts as both transmitter and antenna.
I was still highly skeptical going in to this - and doubts re-enter my mind. But, I’ll kick back and listen to some music. It seems to be sounding better than ever. If it’s placebo - so be it. It sounds damn good!
Peace.
