He was blown away by how much better my cables were.
Wow Phil, he actually thought yours were better 
My point exactly.
All of the A&B testing I've ever done with speaker cable, line level interconnects and digital interconnects have shown no improvements over others (or none good enough to write home about). Don't get me wrong, different cables will have their own sonic merits, but none will really offer better performance in terms of transparency and detail, unless the latter parameters I've described are not in sync.
Synergy is what I think you are referring to.
Better is an adjective and is subjective. If a particular wire adds something you want more of then its better other wise its worse.
Simply saying that “…different cables will have their own sonic merits,” is enough to justify any cost as long as it’s affordable to YOU. Who are you or anyone to say what’s expensive? That too is subjective. The cost of a cable may be a days salary to one person and a weeks to another.
The point being discussed here is whether or not a wire can display ANY differences in sound character. Better, worse, cheap, expensive are all a matter of opinion.
I DIY’ed my own speaker cables. I bought wire from here and there and tried this and that, eventually I found a wire that I liked and it fairs favorably to a commercial wire costing many times as much, unfortunately by the time I add up the cost of that box of unwanted wire, dielectric, spades and allsorts it cost was as much as many comparable commercially made speaker cables.
Now if I had been happy with the Home Depot outdoor extension cord or the Radio Shack lamp cord then I could have saved lots of $$ but I wasn’t and what fun would that have been?
You can go to
www.usedcables.com and try as many cables as you like for NO fee except making a small commitment to buying something from them within a year or so and before you assume their prices are high, they aren’t – actually their prices are on the low side and you can buy used AND new cables from them of all brands. SO you have them send you two or four cables, listen for a couple of weeks and return them. You can keep going till your hearts content.
You can also buy used cables on ebay or Audiogon and listen, sell off what you don’t’ want and keep what you like. Ultimately the cost is low and the fun is high unless you are obsessive and start loosing sleep. All I can say to that is Prozac and a good counselor.
If you just don’t care then you really don’t belong here or any other audio hobbyist forum since that’s what a hobby is otherwise it’s just a tool or utility and deserves no additional discussion. If you went to Radio shack and bought whatever and say to yourself; this sounds fine then you are missing out on the fun and the learning experience. If you can’t justify spending more then RatShacks best and find it necessary to lurk and knock others who are having fun then you are likely just board or lonely. Find another hobby and/or be content and listen to whatever it is you listen too.
bgewaudio, this post isn’t specifically aimed at you. It’s a generalization to readers. What type of components and associated gear do you have? What type of cables do you listen with? What have you tried? I’m not setting you up, just interested.
