In regards to the whole bright/warm amp thing:
I have a hard time understanding how a solid state amp can "sound" either warm or bright.

I mean, what manufacturer in his right mind is going intentionally create an amp that causes listener fatigue?

Of all the talk of an amp having a particular sound weather it be warm or bright I've never heard from anyone (hobbyist or professional reviewer) what exactly causes this perceived phenomenon. What exactly makes an amp warm or bright? Can anyone be specific on the cause without making generalizations?

I live the life I love and I love the life I live.
