1. Should one have the possibility to acoustically treat the room the less Audyssey MultEQ may be needed or can even be turned off,...but there is one condition. One must always listen to movie soundtracks at 0 dB reference level, although having MultEQ on won't really hurt!
2. Should one not be able to listen to movies at 0 dB reference level DEQ is a must. Should one turn it off doesn't mean lack of understanding how DEQ works, but how our ears work and especially why (level dependent frequency depenency).
3. Should one have a desire to use their HT systems with MultEQ and DEQ for music, ...well, there are a lot more things to consider.
4. Should one have a desire to tweak settings or in other words to enter Preference Land it's always A-OK once it is started from reference.
