If you are using the headphone jack out from your laptop then you are hearing the onboard DAC in your laptop. If you want your streamable content to sound better consider buying a standalone DAC between your laptop and preamp. Tidal makes use of MQA compression, there are some affordable DAC's that can "unfold" the compression completely such as the meridian explorer 2. Or choose something like the HRT music streamer HD, no MQA support on that unit.
However if you are serious about achieving a streaming system that can rival your CD's be prepared to go down the rabbit hole :)
