I have just retired and moved and planning to upgrade my entire Home Cinema and related equipment. A problem has arisen which I did not have when I last set-up my system 20 years ago.\n\nThe new system I have in mind is centered around Samsung HW-Q90R Soundbar and its wireless rear speakers. It has 2 HDMI and 1 Optical input but no RCA. I have always preferred to listen to CD music (I have a very large collection) on a dedicated CD player rather than play them though a DVD or blue ray player. For the last 20 years I have had an old NAD player that connected to the Onkyo amp via RCA cables and worked great. As part of my overall upgrade, I want to get the highly rated Marantz CD6006 player but am unsure how to connect it to get the best out of it.\n\nAs I see it, I have 2 options:\n\n1. Connect the Marantz to the Samsung Q90 via optical cable. If I did that, Marantz's own DACS will be bypassed and the soundbar's DAC will take over and play it through the 5.1 system.\n2. The other option is to connect the Marantz via RCA cables to my old Onkyo HTX-22HD, which is a 2.1 system with just 2 speakers and a subwoofer. But then the CD player's own DAC will come into play.\n\nWhich option is likely to work better?
