I currently have a single Play 5 in my living room but am thinking of buying either a Beam or Playbar (and probably adding a couple of surround Play 1s in the future). Quality of music playback e.g. music Blurays, etc. is more important to me than the quality of movie soundtracks. How does the quality of music playback from either of the bars compare to a Play 5? Would I need to add a sub to get the same level of bass as a Play 5? Any feedback would be appreciated.
