I think you mean the DAC is a Delta-Sigma, which some mistake for DSD. DSD is encoded using Delta-Sigma.
https://en.wikipedia.org/wiki/Delta-sigma_modulation
DAC's are either multi-bit or delta-sigma, although I think there's some hybrids with 2 bits, and I think the famous dCS ring DAC was complicated 5 bit Delta-Sigma, but now I may be making stuff up. Schiit makes a big deal of using multi-bit DAC's.
99% of current DAC chips are Delta-Sigma types.
A common feature is "Asynchronous Sample Rate Conversion" though it may be called "reclocking" or upsampling or something. ASRC can go up, or down or even keep the sample rate the same, but with a new low jitter clock.
