Thank you Gonk again!

Your explanation into the bass management is very good. You are a "man". For some of you who may not aware, this bass management switch is only applied to 7.1 analog input. I did go back to my SACD player and re-adjusted the speakers to large + subwoofer. I also re-adjusted my center and rear speakers crossover in the receiver to 100 Hz. It is the best for my speaker size. Therefore, I have no choice but using "digital" bass management setting (HPF/LPF is fixed at 80 Hz). I keep all speakers with the same dB readout when running channel calibration using receiver test tone. I feel it is better than having higher subwoofer output. My audio system sounds pretty decent now.
