With the choices my Denon has given me, I have experimented with this delemma. I think it depends on source, room, the listener's preferences etc. etc. I like DTS movie soundtracks, they seem to have more oomph in the sound effects. I have a concert DVD with a DTS sountrack that sounds great. But, TV with DD 5.1 is also great. Now, DPL IIx (cinema) is fantastic for CD and regular TV, preferred over NEO 6. But I switch to DPL IIx (music) for any music programs. I have just moved my rear surrounds closer together for a more pronounced rear effect, vast improvement and am looking forward to borrowing "The Incredibles" this week to experiment with DD ES/EX. I'm glad Denon gave me the options.
