I cannot get out to test stuff. So, I buy online and when and if it gets delivered (not always a sure thing anymore now that Amazon uses such "reputable" delivery companies as OnTrac) I then listen. I am definitely hoping that what I bought does what it should. But sometimes the product falls a little short. Sometimes it falls short of the online reviews and hype.
So, the decision to buy does affect if I like the product or not, and I am biased in favor hoping the product works out. But, I have not dug in and I can still be disappointed, lick my wounds, and try something else.
For me to test drive the Kimber Kable speaker wire, I would spend over $500 for that wire with bare wire terminations at their website. I don't know if that wire would make fireworks go off and the Blue Angels do a flyover above my Apartment. But if they did not, I would be disappointed. My OFC speaker wires/small tower speakers already sound wonderful in my living room. Those Kimber Kabel wires would need to beat wonderful. That is hard to do. I am not going to be self-delusional and play "Let's pretend these are the best thing since sliced bread." For what those wires cost, I could buy an Oppo 203 universal disc player or spend a little more on their Sonica DAC/Streamer. Either of those OPPO products would be a much safer use of my money than jumping off the cliff for the Kimber Kable speaker wires. I have many more itches that need scratching first before I get the $700 speaker wire itch.
It can be hard to admit purchase mistakes. Some people buy into their bad marriages. Some people stay in bad marriages for decades and become experts at rationalization. $700 speaker wire would probably be a smaller boo boo than a 20 year long bad marriage.
The Audioholics review of the Kimber Kable speaker wire did not say if it beats wonderful. People with Blue Jeans Cable and other brands of OFC wire are already getting wonderful, affordable performance from a very basic, generic commodity like, mundane product. Exotic wire companies are competing against mundane wonderful.
