I have no idea, having never heard the Meridian. 2 questions for you.
1) I believe the Meridian does MQA. If I recall it was the player that came out the same time MQA was released. Is that important to you? Can the DAC be accessed independently? I don’t think there are very many MQA discs are out there.
2) Does the Meridian play SACD, and is that important?
Regarding PS Audio, they are rumored to be having a DAC upgrade soon
