Somebody said that all Monster Cable is snake oil. It's not. Especially with their older products in the hifi world, there is a distinct improvement in sound with their products over basic lamp cord/16ga speaker wire. Is their 12ga 7-nines pure O2 free speaker wire better than anybody else's 12ga speaker wire? No, not really. Are their interconnects a big step up from gimme cables? Yes. If you can't hear it, then I don't know what to tell you other than don't waste your money on something that gives *you* no value. I can hear differences in double blind and ABX. I can tell you in double blind testing if either of my line conditioners is being used--I did this before forking over my own money on them. I heard plenty of gear that did nothing. High-end power cables make no difference over any other IEC power cord. Is there a lot of marketing hubbub and less-than-ideal demo practice? Yes. Does that mean that there's no merit to the products? No.
If you're dyed-in-the-wool believing that wire is wire, then I'm not going to be able to convince you. And I've spent way too many hours successfully identifying cables in double-blind testing (even digital interconnects--must be witchcraft) for you to convince me that wire is wire. We will just have to either agree to disagree or just go our separate ways.
