.....for the sake of very clear mid frequencies e.g.for brilliant piano sound.
I'm not real happy with the piano sounds on my PA3x. So......why does correct amplification "make a piano patch sound better in the mid-range?" Zuki mentioned that in a recent post also. I understand how frequency response works, I just don't understand the speaker/piano sound interaction?
P.S. I like the way you review equipment.....very thorough and very descriptive.
