Hi-Res Edition maintains several pages detailing the majority of multi-channel audio releases, including 4.0 quad, 5.1 surround, and elevated immersive formats such as Dolby Atmos and DTS X. These may be new and back catalogue reissues available on Blu-ray, SACD, DVD-Audio, DVD-Video and downloadable formats such as FLAC and DSD. However, while we attempt to include all multi-channel releases, classical, opera, Soundtracks, and other genres are typically not covered. Additionally, sprinkled among the reviews and release recommendations one may find standard stereo and high resolution releases, but these are not intended to be part of a complete list, rather recommendations for your listening pleasure.
