The MA900 is dark/warm, if anything. Treble's noticeably held back, no real sparkle to it without an EQ to kick it up a notch. Mids and bass are noticeably more prominent. I'm surprised anyone considers that bright...maybe not being able to hear above 14 KHz is throwing me off.
I don't believe in amps as EQ; they need to be transparent while all intended coloration happens at the source. That is to say, EQ on the source.
