A New Believer

I have listened to many systems over the years, and have never appreciated the difference speaker cables can make to a sound. In fact, I was so skeptical of the sound changes they can make that I have always not bothered with any special type of cables, generally going for generic (and dare I say it) roughly made ANY copper wire plugged in to amp and speaker. Well, imagine my surprise when I decided to do a blind test and listen to what difference cabling can make. Wow, my Vand 3A Sig's had been getting strangled! (some of you guys may want to strangle me if I told you what connects I had been using). So I am now a firm believer, cables DO make a difference.
Paul Graham your post REALLY made my smile of the day, thanks! Now I'm REALLY outta here.
Grannyring, I couldn't agree more. The problem I've found is that you have the people that have tried different cables, noticed a difference and then tell others to try it.

You then have others that claim they never need to try anything but just trust the "science" behind it all.

Very very few I find, try it, and find they notice no differences and then still follow the "science" crowd.

I personally don't think you have to spend a ton to get good/great results. Changing out PC, ICs, etc can be fun once you have other set items in your system such as amp, pre, source to just see what differences they make. If someone then finds that it didn't make a difference to them when they tried a few different cables then all the power to them, at least they tried it and then got to their opinion that way.

I just try and encourage someone before they just say "well Roger Russell says this, or science says that" to just pick up a pair of IC's or cables on here, and see if you notice anything. if you don't, thats fine and just sell the cables to the next person, at least then you would have "evidence" to support your claims, rather than just discouraging others from trying something.
I agree with Almarg about price correlation. I am absolutely convinced cable change makes an immediately audible difference, speaker interconnect and power, but price is no guide at all to quality.
Everyone I am sure, is aware of the cost content of expensive cables. Most of the cost is marketing, dealers markups etc. Logically smaller manufacturers that don't spend on advertising and sell direct, can be cheaper.
lou Hinkley from Daedalus Audio was over in the UK visiting last week and we tried out Boulder cables new speaker cable, designed for his speakers, against my Virtual Dynamic revelation cables. The boulder cables cost what $1200 for a 6ft single run, the Virtual Dynamics cost I believe about $7000. I bought them much much cheaper, second hand. They were clearly different, but neither of us could say which was better.
More than any other area in HiFi, I believe price is little if any guide to benefit, where cables are concerned.
I have a sneeking suspicion that cable manufacturers produce more and more expensive lines, quietly astonished at what they can get away with. Unfortunately, some of us customers buy on the basis of price, not quality, if it is too cheap, they won't consider it.
