Choke power supply- part 2

Back in 2008 I asked why choke power supplies were not more common. At the time, the majority of opinions were that choke power supplies were more expensive and so most manufacturer's chose not to use them. Today, with mega priced gear, I still question why manufactures are not more enamored of using them in their power supplies?

I am of the opinion that a choke power supply can sound spectacular and it does seem to offer several technical advantages...so why not more popular? Surely if it is still cost, that seems to make less sense as the price of top flite gear is now approaching six plus figures! Thoughts?
