• I guess it isn't?

    It isn't, it's a general purpose digital communication system. The digital bluetooth stream will go through a DAC process in your wireless headphones.

  • Great. No need to worry about upstream DAC then.

    As you say, just get one of those aptx dongles and that should be as good as it's going to be on Bluetooth.

  • Another upgrade to purify the signal would be a dedicated streamer with USB out to get away from laptop signal noise. Plug the aptX dongle into the output and you might (might) get an improvement.
