I mean it's not like you can just whip up something better than the most advanced AV processor ever made. Throw in patents and decades of development on their software platform, it was clearly a smart move by Harman to license it.
Harman had a world leading team from Lexicon - they sacked them!
Then when it came time to integrate the subsequent generations of AVR/AVP's they were stuffed.... hence the never-ending history of bugs ever since! - Let alone the almost total absence of R&D in the AV space.
So yeah, they don't have much choice other than going out and buying it in from someone else - their own in-house tech is now heading towards 30 years old, and in that time there has been no serious development.
Of course D&M have never been an R&D house in that sense - they were always integrators, engineers, manufacturers.
So the purchase of Sound United, won't resolve the issue - it merely perpetuates it, as they get even more integrators, engineers, and manufacturers, and still no R&D.
Now with SU, they will have the perpetual exclusive licence to Audyssey to add to their "quiver" - but also worthy of note, Audyssey basically lost interest in the product after they concluded the licence deal with SU.... Only the user interface has received (substantial) updates over the last 15 years or so.... there has been no R&D there to develop it further.
Which isn't to say I disagree with your comment
@amira - yes smart move getting what is considered the best in todays market, and using it for the exclusive flagship.... it is just sad when you look at the potential that was there, and was simply discarded.
