Hi there , whilst you wait for a reply I can tell you my experience with the headphone amp section of the dacmagic plus. While the sound through the rca into the amplifier was really great I did not like the headphone amp part.my audeze lcd2's didn't have the life I expected through the dmplus . I was really quite disappointed with it especially as it was such a good sound. I ended up hooking it up digitally to my beresford caiman which was not the same class to my ears but was much better headphone output.
I am on the look for one having taken mine back after a trial. I have several headphone amps now. I was so impressdd with it's sound. I too am wondering how the meridian performs, it's certainly looking at a different marketplace being pc only.
