I can’t speak to a lot of the questions posed, but I have had a Pearl since it was first introduced (serial no 0017!) almost 11 years ago. Wonderful machine: detailed and dimensional. It replaced an Arcam cd-36. I also have an Oppo 205. Neither of those machines, although they both sound good, come close. I just purchased a Ruby for another system. I should get it next week. I’ll report when appropriate.
Everyone, stay safe in the pandemic.
