Me too. I find TV shows are mastered to different volumes and I need to turn the volume up or down. Similarly, I find some TV/Movies/Music are mastered with different bass volumes and I need to turn the bass up or down. Or sometimes the Mrs has a headache and I need to turn down the bass.
For whatever reason, if Audyssey has already set your bass at -11dB, you have virtually no ability to turn it down further.
I like bass, and in fact turn it up more often than I turn it down. But why would you not want that capability if available? It is a choice between having the ability to turn your bass up 20dB, or turn it up/down 10dB. So far, I have never wished I could turn up the bass 20dB. But that's just me.
