• 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.

  • I've avoided streamers so far; quite happy with nas -> laptop -> DAC -> amp for general purposes.

    The headphones thing does provide a slightly different challenge as the laptop is the "source" in a way that it isn't in the loudspeaker output chain.

    I've just ordered one of those aptx HD usb dongles so we'll see where that takes things.

  • No noise in the digital signal whatever the source (unless you’re talking about jitter, which is of negligible effect compared to Bluetooth compression and wireless signal issues).
