I would first try to get out of the bluetooth streaming option you mentioned before any purchase. Irrespective of other gear, the quality of music deteriorates with bluetooth streaming. As an alternative look for a way to stream either via wifi or a direct internet connection. A DAC will help here. Also look for an integrated with built in DAC from Yamaha or Marantz. Otherwise you will spend tons on interconnects etc. The amazon speaker wire should be fine.
