I don't have the 2/08 issue right here, but in the Letters column, someone (JA?) commented that perhaps blind tests don't have "sufficient resolving power" to pick up differences that ears can hear. The easiest way to increase the statistical power of a blind test is to increase the number of blind raters. Given reasonable listening conditions (e.g., familiar source material, components other than what's being tested that are familiar to the raters, sufficient listening time), the more listeners you have, the more chance that a difference noticed by the raters is not the result of chance.
My friend gave me an amp that is about ten years old. It's an old RBH one that looks similar to the ones built into new RBH subs, but this is seperate. Any ways, ive been listening to it for a while and it's worked perfectly, but today when i went to listen this morning, it wouldn't work. I used an ohmmeter to check the fuse, its fine, the front speakers are working, but no power is being delivered to the sub. And i checked all of the cables and they are fine.
I recently read in Stereophile of someone cleaning the non-read side of a cd (and with a way overpriced cleaner I might add) and would like to know what purpose that serves? Is there a measurable difference or is there science behind it? Don't tell me it sounds better. It's supposed to sound better because that's what the manufacturer wants you to believe.
