Oh boy, you have some research to do.
Yes, I used a macbook years ago, and it was trounced by an audiophile streamer/player. I have since upgraded my audiophile streamer/player to a better audiophile streamer/player and music sounds even more natural. Adding quality cabling to all components raises the level even higher.
Don't be fooled by what you read regarding 1's and 0's, and a lossless data stream etc. and "bits are bits". All the sound quality improvements are in the design, the output stages, power supplies and reducing electrical noise. Use your own ears.
But technically my streamer/player is still a computer, actually more than one computer in a single box, just engineered to control and play music only.
