Are you saying preamp eq isn't great like the Monique or other than Monique?Great minds think alike, the Channel One Input One on my Ampeg B-15N(C) is 5.6 Meg! You can have all the different impedance settings you want, but if the pre amp EQ section isn't great (i.e. Monique) they don't matter nearly as much.
Great sound comes from a great pre amp.
