Hi, I have just become the proud owner of a Sony Bravia KD55X8505 4k led tv, and now need to upgrade my sound system. At present I have an old Samsung DVD 5.1 home cinema in a box but feel I need to invest in something better. Most of our viewing is done via a sky HD box and I am an avid gamer using a Playstation 4. The room in question is about 6m x 5m. My budget is around the £500 mark but could stretch a little for the right product. I am looking for some help and advice as I am not the most knowledgeable on this subject. I currently have a stereo pair of play 1’s in the room (I am very happy with the sound when streaming music via deezer or from a NAS). I am unsure whether to go for a Sonos soundbar (the stretch) and add the sub at a later date or use something like the Sony BDV- N5200W or ONKYO HT- 54505(B) set up. I have a play 3 in another room which could also be utilised. Is there any other system that could utilise the play 1’s as rear speakers through an AV receiver, or is this only possible with connect or connect amp which would probably use too much or my budget. So to summarise, should I add a Sonos soundbar to my play 1’s, go for something like Sony BDV- N5200W, or piece together some other system that will use the play 1’s as rear speakers saving me money, allowing for better components for the rest of the set up. Any help or suggestions will be gratefully received.
