Any MP3 players have a digital line out?

I really like the Archos 604 wifi and would get that in a second if it had a digital line out.

Well some portable DVD/MP3 players have digital out like this one - http://www.amazon.com/M520P-Portable-Player-10-2-Inch-Widescreen/dp/B0009RMGTC

then there's stuff like http://www.zzounds.com/item--EDIR09

Audio outputs: Headphone jack (stereo miniature phone type), Digital output jack (optical miniature phone type), Line output jack (stereo miniature phone type)
so i think that would work. itd be nice if standard players had that feature

Hrm it seems there are digital outputs available on cd/mp3 players but not hdd : http://www.ciao.co.uk/Sony_CD_Walkman_D_NE1_CD_MP3_player__5602294
