sorry I am just catching up to your question.
I have not experienced any of what you have with the Morpheous with RCA terminations. The Poseidon Signature offers more detail , I don't have the Poseidon Reference RCA , I do have Poseidon digital cable. The Orion is the highest level Silnote RCA I have and it takes the music to another level , again without any displeasing aspects to my ears
