Looking for suggestions - CD Changer 2 mod & use w DAC

Would like to hear from anyone who has taken a cd changer (5 CDs or more) and modded it to use with an external DAC through digital out. Not worried about TOSLink. What changer did you pick and why? What mods did you do? Power, pulse transformers? I saw Dorkus':wiz: project but am more interested in a changer for use with external DAC.

Thanks!
