@jazz99 I have a bit of a different solution for you. I have an old pair of Acoustat 1+1 that had real problems with modern class D, and variations of it, due to the low 0.5 Ohm dip in the upper treble. Even though I could not hear where the issue occurred I could hear the result due to clipping (Schiit Tyr, PS Audio M700 and others). I tried the Coda #8, but did not like the result, although there was no clipping. I ended up with the Pass Labs XA 25. I was concerned that the power might not be enough, but since I use an active crossover (SPL Crossover from Germany -- similar to the JL CR1) with dual powered subwoofers, the XA 25 ended up being a tremendous match.
If you get a chance give the XA 25 a trial run.
