When I listen to Spotify the bass is excellent. Much better than previous Outlaw Audio preamp. Movies have good bass but lower than expected; I'm sure I can adjust that. The problem comes when playing CDs on my OPPO bluray player. Bass is ridiculously low. I've tried HDMI, 7.1 direct analog, and stereo analog. It's not settings on bluray player. My outlaw audio had great bass when playing cds. I've adjusted my subs to +3dB and little effect. I have tried many settings but have not run Audessy because I'm waiting for when I install height and side speakers. I bought a refurbished Marantz AV7706. Did I get a bad one with bad analog inputs?
