I keep 1TB worth of music files in my phone's MicroSD card (or Qobuz streaming) ---> Cayin RU6 R2R Dongle DAC ---> Sony - WH1000XM5 (noise cancelling/wireless) headphones
When i carry a laptop during travel, it is for work. The music stays with the phone. A PC isn't required for me to enjoy high fidelity music during travel.
