Upsampling to DSD 64 with Benchmark DAC3 [USB Audio 1.1 default, switch to USB 2.0]

I’m glad that worked for you. Benchmark ships the DAC3 in UAC 1.1 mode by default because it wasn’t until fairly recent patch levels of Windows 10 that it supported UAC 2.0 without additional drivers.

These settings have to do with the algorithms being used to convert from PCM to DSD. Here’s a post from @brian regarding how they work:

My personal preference is for PCM over DSD (particularly single-rate), but you should figure this out for yourself, as it has a lot to do with the specifics of your equipment and your own personal preferences.

This setting is mostly for working around buggy devices or drivers that misbehave otherwise. I wouldn’t touch it if you’re not having issues.
