Hi all, is it rare for a driver to fail? Essentially the sound signature of my CM Mest II has suddenly changed in that vocals now appear to be originating from slightly left of centre. For example, Oleta Adams, Get Here, her voice should appear to come from dead centre of the stage, which is where my Sundaras puts them. Her voice now appears like around the nose corner of my left eye. It's moved maybe an inch away from centre. Other aspects like bass, treble, width seem to be unchanged! It has literally done this overnight which is so weird! I've had them since around end of January, 2022. I have reached out to the company I purchased them from and thankfully I can send them back to UM to be tested (and then hopefully fixed!) Has anyone else had this issue??
