One of the best CD players I have ever heard or owned is the Denon DCM 560, it has a coaxial output. Even though it is a carousel the dual burr brown DAC’s were outstanding. It painted a life like portrait of the performer’s. Amazing and transparent with a ever so slightly warm sound. I am searching for a used one on eBay. They are hard to find. Currently I have a nad 514 that is nice sounding but not quite on the same level.
