I have an Alchemist Nexus APD32a mki. I bought it new in late 1990s. It was always a good sounding cd player and still works fine, but I'm wondering if a new DAC would improve the sound? I know the answer is it depends at what price point. I am looking at $1K give/take for a DAC and can be used. Also I would like option for headphones but not for only CD but also turntable. Is that possible to have a DAC with headphones for all inputs?
