Again more circular arguments. How do you know that the other drivers are more technically competent and have less limitations ?
You ignored what I said about "small", so I will repeat it again. As regarding size, I don't know of any connection between driver size and quality. Size is generally necessary for volume/efficiency or bass.
Your argument seems to be "the T50RP driver is inexpensive and small, so it must be wimpy relative to drivers used in more expensive headphones".
The entire reason that there are so many T50RP mods by people like Dan and LFF is that the driver is capable of producing sound quality far beyond its cost.
Because they sound better?
The size of the driver obviously has a consequence on the sound, otherwise why bother to make it big or small and just make it the way it is most affordable to build with no other concerns?.
Yes, some small drivers might give you deep bass extension (in small rooms, though) but look at the other end of the spectrum: are they good at reproducing mid-range in such a configuration? The answer is most likely a big no.
Take the Airmotiv 4s, for instance. They have excellent mid-range and the bass feels adequate if you have no comparison and an adequate (read small) room.
But then switch to the 6s. The bass is more extended, has better punch/definition and the mid-range stays pretty much the same. Everything else stays the same.
Which one of the two would you consider the better speaker then? The 4s are very close in most area, except bass. The driver is the same technology, but obviously the bigger one is the better one here.
The bigger driver has an obvious advantage in that it has a bigger range of operation. It is what it is. This is enough to make it the better driver of the two, IMO.
What Dan achieved with the T50RP is probably fabulous (and this is my opinion), but I still feel the ADs lacks bass extension and tactility compared to the MDs. Same drivers, different operation. If one cannot have both at the same time, then it is safe to say that the driver's limit was reached.
Things can be pushed more by designed new cabinet (cups here). This is what happened with the ADs. Overall, they are (much) better than the MDs across the board, but out of the 100% change in sound (be it tonality or technicality) is feel """only""" 80% was for the better. Bass belongs to that 20%.
That's still a very good score here and yes, I'll say it again, the Alpha Dogs are clearly the better headphones and retain almost the same (very good) value as the MDs in a pricier segment.
