Thanks for the fast response. So I understand you suggest the Beoconnect Core (new). I mentioned the BeoSound Core (legacy). Will the BeoSound Core be sufficient or is the Beoconnect Core needed? This first one is available for around 300-400 € at eBay where the later is > 1.000 €. Furthermore the BeoAmp 2 is also very expensive, more like 650 €. Therefore I tend for a 3rd party solution as it should be a budget solution. Its just for background music.
You mentioned Adapter Cables to run 3rd party Amplifier and Speakers. What would I need here?
