I think what is being mentioned as missing with this NAD-Dirac thing is that with my T758 and it's original low-level Audyssey, I could go into the setup menu anytime and bump up (or down) output level of any speaker by a couple dB even after Audyssey was run. If I changed it there would be an asterisk appearing next to the setting until I set it back to what Audyssey had calculated, although that indicator did disappear after a firmware update. Typically, I might want the center speaker to run just 2dB hotter with a movie that had a lot of very quiet dialogue. It wasn't super easy such as having a single button on the remote, but once familiar with the on screen menu it was simple enough.
Can this or something like it also be done easily with the T758v3, or does one have to go to the computer and make the adjustment within Dirac? How do you toggle between the 3 different Dirac profiles that you can save?
