So I would rather regard 5i-A as a "music server" that read music files I got somewhere (ripped from original CDs or from music files downloaded from websitesm like HD tracks). As I listened to it last time (without those good cables), its performance was already great and way beyond 6K expectation. And I am highly interested in it in replace of my cheap CAS.
For videos, like BD, I do think that it is a bit rare in Hong Kong at the moment to buy a BD from a shop, say Batman, Lord of the Rings, and then transform them into harddisk in iso files (say). Unless BD download becomes popular in HK, harddisk players are still a minority for videos.
