No its not stepped. I'm gonna get some attenuator plugs to put on the rca inputs see if that takes it down a little. Luckily there doesn't seem to be any imbalance at the lowest point. I can tell that my Senn's are being fed more power than they are used to. The sound is bigger with more authority, and the soundstage is just amazing! Do you happen to know what the power specs are through the hp out? I know it gives out 20 watts per channel for the speakers apparently, but can't find any info about the hp out.
