I just recently replaced my Yamaha RXV-995 with a Denon 3805. I have gone through all the setup procedures. When listening to music there seems to be a lack of bass. I have adjusted the bass level to +6 and it gets somewhat better but not near the bass output that my Yamaha was putting out. I have Klipsch KLF-20 speakers up front and 12" B&W Subwoofer. I have set all speakers to large. My Yamaha had knobs for the bass and treble and a loudness button. The Denon seems to do this electronically. Does the Denon have a loudness setting that would equal the loudness button on my Yamaha ? or am I doing something wrong ?
