I really and truly believe you heard a difference. I don't doubt the reality of that. You don't have to convince me of that.
However, hearing a difference can either indicate a real effect or a placebo effect.
What did you do to rule out a placebo effect?
Sorry to be repetitive, but if you clearly claim something is NOT a placebo, I want to know the basis for the statement. It sounds to me like you strongly believe it is not a placebo effect, but have not done anything to rule out the possibility.
Honestly if you prefer the sound with your new cables, more power to you! Personally I think music sounds better in low light rooms and I have no explaination other than it puts you in a more relaxed mood and clears your senses. I also think my system sounds better at night than during the day despite the noise floor in my theater room remains constant. Maybe it has to do with barometic pressure or my perception. Human perception is a very powerful tool so if it takes expensive cables to improve your perception, go for it and ignore the trolls!
I think that unless you conduct a double blind comparison of different cables, many people (including myself), will be sceptical that you really hear a difference. Sorry, but you will not convince us otherwise. If you don't care if we are convinced, that's OK. I won't try to convince you either. I can't speak for others though...
I hope you can all consider then that it will be hard to explain. I’m very tuned into sound. I (over) analyze everything I hear. At work last week, I kept asking “what is that high pitched squeal”? No one else could hear it. Turns out, it was a low battery warning on an AED unit on another floor. Please don’t get me wrong – I’m not trying to brag, honestly I wish my brain didn’t tune into and hyper-analyze every little sound I hear.
With the different components, including cable, my focus can turn from hearing the music notes being played to picking up on the most minute distortions in sound. In my particular system, I thought the distortion was from my amp or pre-amp. I switched from an average 14 gage wire to an “underdog” brand thinking there wasn’t any difference, but there it was – distortion. When I switched the speaker cable, the distortion went away, and all that was left was the sound. The very real effect of lobbing also disappeared, and I had a very smooth coherent soundstage. The Kimber was my RCA patch, the new speaker cable – (takes a big gulp as I realize this may get me banned) are Monster Z3’s I got for 75% off ($75) from accessories4less. I hacked them apart & converted two lengths into a bi-wire setup, and honestly, my system has never sounded better.
I find I can also remember distinct characteristics of a certain item, and hear differences between it, and another like item (receiver to receiver for example). What I continue to struggle with is why so many people tell me it must be in my head, or ask for verification. Why isn’t “taking my word for it” good enough? Would I be going too far by suggesting that some people must think “If other people can hear a difference, why can’t I”?
I know I’m not alone in this camp, but right now I feel like I’m standing up for others who won’t voice their observations. I’ve seen other people extol the virtues of the “sound” of a new amp or processor, and everyone says “good on you”. I feel like I’m on trial to prove myself, and it just feels wrong.
