Initially reported to an old PR implementing MBS-13690:

it looks like e-onkyo has unfortunately ceased operations as of 2024-10-16 12:00 JST, with its catalog being merged into that of Qobuz. Furthermore, links that were formerly valid (e.g., for a release) are now unusable, as they simply redirect to the front page, which shows a banner about cessation of operations.

Hence all these URL relationships should be marked as ended on 2024-10-16.
