Gotcha
I’ve converted my entire music library (CDs) to FLAC files. I store them on a NAS and use Volumio for playback.
NAS > DAC > Volumio > Amp

Keep in mind that when you download HD audio tracks it’s important to verify that the service used a high quality master for the HD audio file, otherwise you’re just getting upsampled garbage.
It’s best to enjoy what you have. And then as time progresses and new (good) remasters become available you may decide to revisit a couple of albums that are worth the upgrade. At least that’s my philosophy.
