In fact, excepting for personal preference, it’s likely to be worse to upsample anything to DSD external to the DS. If you have to change the from double or quad rate DSD to a lower rate because of the limited bandwidth thru the bridge II I’d recommend to go to 24/176.4 not single rate DSD. The possible exception is if you know that your DSD to DSD sample rate converter does all of it’s math at the highest sample rate of the input and output. Most go to a lower rate PCM as an intermediate step to avoid filtering at the high DSD sample rate.
Of course, use whatever path sounds best to you.
