Neither, play the DSD.

Ultrasonic noise is a problem when downsampling DSD to a lower sampling rate. If the filters do not prevent all aliasing, then the ultrasonic noise will fold down into the "audible band". On the other hand, if the filters do eliminate aliasing then the result may be filter artifacts and unintended loss of sound quality compared to the original DSD. The solution to this quandary is to avoid downsampling DSD to lower sampling rates. Get a DAC that will play these files in their original format. If this is not possible, then downsample them to the highest available sampling rate.

Given that you have to downsample them until you get a suitable DAC, then by all means use the highest sampling rate available. It will do the least damage. However, even going to 352.8 is not going to be transparent compared to the original DSD.
