The SHD Studio is cheaper on Audiophonics than the Flex when you include the Dirac with the Flex (Dirac comes with the Studio). I still think the Flex is the one for me and most likely direct from Hong Kong. There has been some discussions on ASR previously where a SHD (or SHD Studio?) purchaser was unhappy with the customer service from minidsp (and the US retailer), I can't seem to find the discussion on ASR right now.
