^ Do you actually use the balance control in the Windows settings?
I use Foobar2000 to play music and typically use the foo_dsd_asio output driver. I have no reason to use a balance control at all.
If I am editing in Reaper, I can use the internal (64FP bit) controls of the DAW.
I'll say that I think I prefer the sound of the volume control in software (Fb2k or reaper) over the volume control in the Topping driver (or Windows volume), which I think adjusts the ESS chip directly. I haven't performed any measurements, and so I am well aware I may just be imagining it, but what I feel that I hear is some kind of loss of body when using the Topping volume control.
I am not fussed at all, because adjusting the volume control at all stops DSD playing natively anyway, and I have no issue with the global-key-controlled volume in Foobar2000, so a moot issue if it is an issue at all.
Additionally: For anyone who cares.
TASCAM/Teac have a free program called "Hi-Res editor". It allows transcoding DSD <> PCM as well as playing back to the Topping DAC and transcoding on-the-fly or playing back native format.
KORG Audiogate also works with the Topping DAC but because it's the Lite version is limited in a lot of ways.
If anyone fancies comparing their PCM tracks played as DSD, they can transcode using the TASCAM program and give it a try. Without an extensive test, I don't think there is a massive difference, and what difference there is I'd probably attribute to rounding errors and whatnot. Others might experience different results.
