This does provide another rung up the ladder for people that have allot invested in a USB system without spending a ton to beat it. Surely you must understand that perspective.I for one appreciate discoveries and possible hidden gems on a realistic budget. Although $1270 is a hefty sum for another device to add, it gets its own supply, own ground, own chassis, makes the USB source matter less. It is helping a big problem.
Another option, the Totaldac GIGAFILTER. It is a similarly priced cable that has been amazing in my system. Of the many upgrades in my digital system, this one was the most significant. I believe it is doing allot of the same thing as the one mentioned in the OP.
