I came across this post which I thought was a very good read: http://www.avguide.com/blog/guest-bl...g?src=Playback
Also, this is the link he refers to regarding speaker cable testing (with actual speaker loads):
The author expresses reservations about double-blind testing and support for the idea that digital cables might make a difference to the sound. Agree or disagree, I thought it was an intelligently-written piece. Here are his conclusions:
- Don't be too quick to think you understand everything significant about the role of any part of an audio system. The fundamental scientific attitude is curious and appropriately skeptical, not judgmental.
- Claims of audible differences in components must also be subjected to both curiosity and skepticism. Could there really be a phenomenon creating an audible difference? Think creatively - what could that phenomenon be, how would we identify and measure it? Is that phenomenon significant enough to be audible?
- Remember what Bob Stuart says: we don't yet know enough about how we hear and listen to rely solely on measurements. Listening is the final, most important test.
- When presented with information or claims you don’t understand, don't rush to judgment and accuse other people of credulous idiocy. It's both unseemly, and very unscientific.
