You can use a computer but a good streamer with a dedicated LPS power supply ,and upgrade the signal using a ddc or reclocker ,this too applies to streamers it takes the digital signal ,holds it in a buffer then uses a much higher grade clock and filtering to create a much more pristine signal to your dac ,,
another added benefit is that you can run the best audio signal I2S cable from the reclocker. online they now have pretty decent USB to I2S converters if you just want to run it into your dac, depending just how good your dac cleans the incoming signal. for even the little linear power supply in your streamer cannot match what a good DDC can do . In mine I took it up a notch, and went from Femto clocks
to precision. dual Oven clocks ⏰,plus a lot of filtering , and isolation using I2S Cable from DDC to the dac ,a Big difference in musicality for just over $1k , if you have a more moderate system around $550 for a decent one ,,buy a respectable cable ,they look like a hdmi cables, Wireworld work well nothing under $70 like the Sphere ,or Silver Sphere around $270 , to me. A worth wild option , you can spend $10k on a ddc but that is overkill IMO,That being said ,I have heard $100k digital setups ,for people with Ultra budgets . Way out of my league even when I owned a Audio store.
