Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

DSD means One bit.

DSD refers to 1 bit PCM at an oversampled rate, typically generated by a sigma delta modulator. Most DACs that use a sigma delta modulators do so in a chip and the output of their modulators has more than one bit, e.g. in the case of the SABRE chip 6 bits (8 channel mode) or 8 bits (2 channel mode). SABRE chip DACs (and others using similar chips) are not DSD DACs, because they use more than one bit.
