yeah. cleanest sounding amsp ive used yet. noticabley better than my rf 600a4 (which was still an AMAZING amp). I heard the same era old school earthquake amps sounded better than the arts in a direct swap.....but they're not nearly as sexy.
I wish my work schedule wasn't as hectic, ive been riding around the past few days with no front stage at all....just a **** ton of bass on tap. it's been fun listening to sine wave sweeps but i miss my highs.
