Alec ... if I could trouble you to stay with this topic a little ...
I have the HD-SX6 hard drive ... is that the one you talk about that can be hooked up to a pc? ... I have done just about NO 'experimenting' or 'digging' into the kn6000 OR the HD-SX6, but the hard drive does have features you mentioned such as the playlists, the "Juke Box" feature with auto load and auto start, but I do not know if it has the 4 audio outs you mention, or the PC connectivity ... Can you elaborate on those? ...
With the 4 audio outs, can certain voices such as drums and or bass be output let's say to a mixer, so that the player can adjust those volumes individually?
As always, thank you for sharing your wealth of knowledge ...
