seeking dac with de-emphasis circuit

Being a CD collector from way back, I still have a number of CDs that were released with a pre-emphasis curve (for example, many classical works on the Denon label, some early Columbia discs, etc.). Back in the old days, most CD players had a circuit to detect this pre-emphasis and would automatically switch in the necessary de-emphasis for playback. But my Cambridge 840C lacks a de-emphasis circuit -- which is annoying, but apparently many recent players and DACs have decided to do away with the de-emphasis circuit. I'd still like to be able to play those old CDs at times, so I'm seeking an under-$500 DAC with de-emphasis. Any suggestions? Thanks.
