02-12-11: AntonkkWhich output tap are you using (2, 4, or 8 ohms), and have you tried the other ones? If you haven't tried it, I suspect that going to the 2 ohm tap may help, assuming this is the impedance curve for your speakers.
My main problem right now is the lack of power in the bass region with weak and muddy bass.
