No, missing the point (or I'm not explaining myself well). For the sake of argument say UE900 was a triple driver and came out 4 years ago when TF10 did....and it sounds exactly as it does. Then let's say today, UE comes out with TF10 and let's just say it is a 4 driver and also sounds exactly as it does.
UE could chartge $800 for TF10 !!! "BIGGER BASS, FAR MORE EXTENDED TREBLE....." And people would buy it! You could certainly sell and market the TF10 as a big bold upgrade to UE900.
Just trying to point out the power of marketing, perception and persuation.
That's a horrible analogy...
