The DAC you have is Schiit's most expensive DAC, you can find out now or find out later, there is no getting around the fact that USB cords matter and none are better than the WW Starlight Platinum 7. Is it insanely expensive? Maybe, Is it worth the investment? Absolutely. Buy one new or used, and if you don't find yourself gobsmacked, you can sell it quickly for no less than 80% of what you paid for it. You will not end up selling it.
I understand that in your current configuration you have four sources and only one uses USB, and it's a laptop. If you want to get the most out of your DAC, use a music storage device that buffers high amounts of the music data and has none of the "noise" that a laptop has, e.g., an Aurender or the like. This would be your source for ultimate audio playback of digital files.
