Signal break up on 7 month old Bluesound Node 2i


I stream music on a Bluesound Node 2i using Tidal.  I hard wired my Bluesound using CAT6 cable and I connected the Bluesound by way of RCA cables to my ARCAM AVR 550.  All of a sudden after many hours of listening, I am experiencing signal break up and a stuttering sound when playing one album titled, "Eternal Light" by Morten Lauridsen.  So far, I am not experiencing this problem when playing other albums from my library.  I wonder if anyone might have experienced this problem and if they know what might be causing this problem.  My Bluesound Node 2i is about 7 months old.

I also wonder if anyone can hear a difference when playing MQA Tidal recordings.  For some reason I think I can hear greater clarity and a larger sound stage.  Is it possible when playing my Bluesound Node 2i connected RCA to my ARCAM in order to get the complete unfold of MQA if I am hearing a higher resolution.  Perhaps higher than 24/96.  Unfortunately, the Bluesound does not display the level of resolution as when I was playing it through a ProJect S2 DAC.

You are all so knowledgeable and I will certainly enjoy reading your responses.

Since it is only one album I would think the file has gotten corrupt. I would RIP the album again replace it in my library and see what it does.

I just listened to "Light Eternal", (not Eternal Light) and hear the same thing, however, I have no basis to compare because I don't listen to that type of music.  It almost sounds like it's supposed to sound that way?

That's what MQA is all about, so yes it should sound better.  Tidal used to have some of the same album in both CD and MQA, which made it easy to compare, but I just looked for some I know they had and they seem to have deleted the CD copies.  Maybe there still are some?

The Node2i decodes MQA internally through it's DAC, then sends it out through the RCA analog outputs.  That's how it works, so you're getting the full (3) unfolds and full MQA decoding.
