Do you mean resample DSD128 up or resample up to DSD128? Regardless, I did neither. There is no option for resampling DSD in the Foobar plugin. Isn't 352.8 equivalent to DSD256?
FWIW, I use ReplayGain so albums all have the same relative volume. ReplayGain doesn't work on DSD, big surprise, so I convert everything to PCM on the fly on playback. I only save content in its original format since anything I want done for playback can be on the fly. I like to have the option to be able to go back to the original, bit perfect, file which you can't do after you've done something to the file.
libsamplerate plugin is also converting DSD into PCM at the core. But it is also "cleaning up" the signal in the process. It does so even when down sampling.
From what I read, ReplayGain analyzes the track volumes and headrooms in the digital domain. If so, your digital work flow for DSD looks like this:
DSD Source --> Convert to PCM --> Adjust Volume and headroom of PCM --> Libsamplerate resampler --> DAC
DSD source is subjected to conversion twice before the digital stream reaches resampler. In such a scenerio, you may or may not find any improvements by resampling.
My DSD workflow path :
DSD Source --> libsamplerate resampler --> DSC
