Oops. Should have read more of the other thread. Before posting to it 
Anyways - its late and its been a long day so I'll post here as well 
Its my office PC setup -
Athlon 64 PC (just built it today - well chuffed - leaves my old P3 for dust )
Cambridge DacMagic dac (off the PC's toslink out)
Used for Internet Radio and HD playback
Other sources - Michell Focus One/RB250/NAS Tracer 1 and a Marantz CD63.
Going into a Marantz 66SE KI Sig and a pair of Tannoy DC200s.
I rather like it, but the Marantz gets swapped out next week for my old Sansui AU6500 - cos I love them knobs and there is something quite funny driving a hi tech computer thingy with an old jap amp from 1972
