Admittedly, most - if not all - off-the-shelf computers are unfit to stream digital music. They don’t have a place in a proper audiophile system.
But a purpose-built computer absolutely does. Usually this means a machine you build yourself of thoughtfully selected components, and properly set up and configured OS and software.
Or, get a Bluesound Node, LPS and nice cables, feed it to a good tube DAC (with really good NOS tubes) and be done and happy for ~$3K (+ $11 a month for Qobuz and SXM for free if you have SXM in your car) - and a nice app to control it all from every phone and tablet in the house.
