"I doubt the output stage of any Sabre DAC would come near a SN of 130dB.
Let alone the rest of the system as a whole."
The link shows claimed S/N numbers for several models. The actual S/N ratio depends on the model number (e.g. the more expensive chips are selected for lower noise) as well as the configuration (more switches are used in parallel when the chip is run in mono than in stereo or multi-channel).
There is no theoretical reason why these chips couldn't meet their claimed specifications. However, the numbers are likely to be as good as any available test instruments, making it difficult to argue with the advertised results. ESS has a white paper that describes how the chip works.
