I'm curious about this "DNA" thing as it comes up every so often. How does DNA manifest itself? Is it in the core decoding? No--that is done by the same chips and algorithms everyone uses. How about bass management? There are indeed differences among processors there. Filter slope, number of sub outputs, ability to define different settings for different sources. Is this where the magic DNA comes alive? How about post processing, like Dolby or DTS surround modes. Some do offer their own modes, but we're talking movies here, so is this really a key differentiator?
BTW, all the things mentioned thus far have nothing to do with cinema heritage or DNA, as cinemas use none of this stuff. Zero.
Ok, let's turn to hardware. The Datasat RS-20i comes from the AP-20, designed expressly for cinema use. Now that's cinema DNA. Except the RS-20i does not use that hardware. All the analog stages and power supply were replaced for home use (and for very good reason -- it was too noisy). And IIRC that design work was done by ATI/Theta, not by Datasat, per se. Correct me if I am wrong.
Not to pick on Datasat, let's talk about JBL. What is a JBL surround processor? For many years is was a Lexicon with a paint job and a few programming settings. Now it is a Bryston with a paint job. Both of which feed some professional external EQs that are set by a sophisticated program called ARCOS.
Ahh, so the special DNA is perhaps the EQ. ARCOS is very highly developed, and so is the Dirac Live in the Datasat. I would say RoomPerfect is also highly sophisticated. So by this reckoning, I cannot see "DNA" as a relevant factor regarding sound quality for movies among these three processors.
Now when it comes to easy of setup and use, that's a whole different story.
