John,

Thanks for the advice. Have been playing around with the settings and somewhere from -3dBs to -2dBs seems to work depending on the disc. Didn't like the idea of using the variable settings on the Marantz so I kept it on the fixed setting. My Velodyne's setting is at the 9 o'clock setting and like yours has a long way to go. But even at this setting, I can rock my whole house! Luckily, I don't have any neighbors to contend with so I can let the cannon blasts fly! I guess with all this discussion on settings, it still boils down to what our ears think is correct and pleasing to us.
