I'm pretty much a newbie but I have spent a good bit of time over the last couple months auditioning speaker systems. I definitely have a preference for sound generated by what is referred to as warm systes vs. bright (or even revealing) systems. FYI...I determined that I have this preference by taking notes on systems I listened too and later looking up reviews for that speaker/component. In other words, I used a pretty unscientific methodology . If I were to look at the audio spectra for a system that appears to be "bright" vs. a system that sounds "warm", what differneces would I see? What physical phenomena with regards to construction and composition in speakers, amplifiers, pre-processors, and cables leads to warmer sound? Finally, does this indicate a bias or defiency in my hearing? or is it just a matter of taste?
