Who can repair a Resolution Audio CD-50???

I bought my Resoluton Audio C-50 on Audiogon about 6 months ago. It's as nice-sounding as I had hoped it would be and it has the added advantage of having a quality internal volume control, allowing me to go from it straight to my amp. It has just developed a fault: when a disc is inserted the readout says "err." So there's something wrong with the disc drive. I contacted Resolution Audio and they responded that it is unlikely they can fix the unit as the Philips drive unit they were putting in the CD-50 and CD-55 is cheap junk and, in any case, is no longer available. They suggested that they might be willing to take the unit back with some credit toward purchase of their latest CDP...oww! Retail of this model was $3000. It's hard to believe that it is now useless trash. Anyone know where I can get it repaired? Many thanks.
