I have owned a KPS 28c for several years, paired with a Krell amp and pre-amp. About a year ago, it stopped reading any inserted CD so I arranged to send it back to Krell for repair. For $335, Krell replaced the step gear and belt and returned the unit to me; problem was, it still did not work. Krell apologized, stating that it must have been damaged during shipping, sent me an RMA label and I shipped it back to Krell. A month later, I had the unit back for a second time. Still did not work. I have attempted to contact the rep at Krell 4 times and, quite surprisingly, no longer get a response.
