AquariusSACD

AquariusSACD is a term that appears in some discussions about high-resolution optical audio formats. It is not tied to any officially recognized standard or released product. In most sources, AquariusSACD is presented as a hypothetical or aspirational concept within the lineage of the SACD format (Super Audio CD).

In these discussions, AquariusSACD is described as a potential successor or variant intended to retain backward compatibility with existing SACD players while offering enhancements such as expanded channel configurations, higher bit-depth handling, or more robust archival features. Proposals commonly reference Direct Stream Digital (DSD) encoding and multichannel playback, hallmarks of SACD technology.

Disc structure for AquariusSACD, as imagined by enthusiasts, often includes a high-resolution audio layer based on DSD or PCM alternatives, possibly combined with a standard CD layer in a hybrid disc design. Some concepts envisage improved error correction, longer recording times, or more efficient authoring tools for archiving musical performances and multimedia content.

Status: There is no formal specification, licensing framework, or commercial rollout associated with AquariusSACD. The term is mainly found in speculative forums and hobbyist projects and should be understood as a hypothetical concept within the broader SACD discourse.
