Escoteric K03XD - Loss of high frequency in right channel

Hello folks, I puchased a brand new Esoteric K03XD 3 years ago and this week the right channel lost its high frequency, left channel is fine. Never had any issues before. I tested it on several other systems and it does the same thing in every scheanrio.
I am looking for any help or guidance on this matter. Anyone else have this issue with this player and if so, what was the resolve? Thank you for your time.
