Despite the tech debates in this thread (I've certainly enjoyed tossing around a few theories), I don't think there is any one answer in HiFi yet. If there was then everyone would use it. All technologies have benefits and disadvantages. So it really comes down to personal preferences. Also, many of us in HiFi get obsessed with one tech or the other and prejudice ourselves too easily. This is why you see persons having to confess that X brand or Y tech surprised them by sounding good... For example; Just because someone has never heard a horn speaker they like, doesn't mean that all horns sound bad, and one day that person may well find a horn that does it for him... I've seen persons bad mouth a particular tech/brand for years and then turn around and buy them (perhaps their tastes changed or perhaps they were too prejudiced to give the item a fair chance before, either way it shows how silly it is to get obsessed with any one belief system)...

As I said at the beginning of this thread: we will still be debating tech in the future. And until we finally figure out how to measure everything that affects why we hear what we hear, then I can't see any one tech reigning supreme. Sadly, I find that too many brands are either obsessed with traditional (insufficient) measurements, while others seem to just dismiss measurements entirely. So in extreme (yet not so uncommon) scenarios you'll have brands producing 'technically perfect' but awful sounding gear, while at the other you'll have a designer in a remote cave in Japan tuning an exotic amp by ear, that sounds magnificent but has a 50% chance of exploding and killing you, when you press the power button...
