Friends a new member here from Pune, need your advise and opinion on my first HiFi purchase. Want tobuy a AVR with bluetooth/USB port and 4k upscaling, at least 4-5 HDMI inputs. I need to know the speaker set:up that will go with this type of AVR. I will start with 2.0 or 3.0 (center channel) may be add a sub later. Which make of speakers would you all advise? (hope to get all from the same manufacturer to avoid problems with compatibility)
