Isn't it amazing how our brains interpret what we hear?
For example to me....
Warm: Marantz, HK
Neutral: Onkyo, Integra
Bright: Yamaha, Pioneer
And my definitions of the above..
Bright is in your face, edgy but not so much as to cause
sibilance. Just really energetic on the High Frequencies.
Warm is calm, not drawing too much attention to it's self.
If I were to use women a anlogy a warm woman would be one
who doesn't need the fancy dress or makeup to look good and
she treates you right.
Neutral is somewhere inbetween both of the above. This is
the woman i'd marry if I used the above analogy.
Everyone hears things differently. If we all heard the same
there would be one speaker made. If we all loved the same
woman we'd be in trouble! (Or, would she?
