Psychological expectations work both ways. Sometimes I don't expect to hear a difference and then I do. Sometimes I want whatever I just tried to do what I expected and it doesn't. I am always a little skeptical about some tweaks but try to remain open minded. Sometimes I am surprised.A bit more on topic - with cables and such, I'm a bit of a skeptic. They do matter up to a point. After that point, it's either a difference when using a spectrum analyzer or psychological (I WANT to hear a difference, but is there really a difference?).
Hey man, we are all like that. Sometimes the gain just isn't worth the cost.So, as it's my system, if I can't hear a noticeable difference, I may not go for it. Other people might hear a difference, but they aren't in my room listening to my system. I want the best, but eventually I'll hit the point of diminishing returns. Whether that is at a 14 gauge gold plated, twisted pair cable or a $20 vs $200 HDMI cable, I'm not sure.
