Well, like the thread title states...I'm a bit confused as to the advantages of having a HU with DTA over one that doesn't.
I'm kicking around the idea of upgrading my HU once I return stateside and as I am a rather loyal Kenwood fan the choices would be either the eXcelon KDC-X889 or the 25th Anniversary XXV-01D. I know that some say the only real difference between the two is the XXV has a bit better display but according to the stats on paper it is allegedly built with better internals than the eXcelon stuff....but that has nothing to do with why I've made this thread.
The 4-band EQs I feel confident that I could work out pretty easily. I'm further intrigued by the ability to use different EQ settings for the front and rear simultaneously. This seems like it would allow for a bit more in-depth system tweaking than my current HU allows for. I have heard/read from several trusted sources that the presence of the SRS WOW processing does more to detract from the sound quality than it does to improve it so it being part of the onboard processing doesn't particularly impress me much.
The DTA, however...I've never had a HU that incorporated it. Seemingly every HU that has it which also has an automatic DTA setting option seems to garner reviews that the AutoSet feature leaves much to be desired and that the user would be much better off making these adjustments manually.
What advantages does having DTA provide and how would one go about setting it having no real previous experience doing so?
EDIT: An involved answer isn't absolutely required...YES, I DID search. I found no in-depth discussions on DTA but rather simply mentions that this HU or that one actually has the feature. If there is an pre-existing online discussion about it that someone can link me to I would be most appreciative!
