Beolab 6000s have both a powerlink and traditional LINE input sockets.
But it depends on what your Samsung outputs its audio signals as; if the Samsung supports traditional passive speakers DO NOT connect the beolabs.
What model is your Samsung, where does it get its video signals from (e.g. where is the DVD, Blu-Ray, Set Top Boxes, whatever) in your setup.
First B&O (1976) was a Beogram 1500 ... latest (2011) change has been to couple the BL11 with the BL6Ks *sounds superb*
