I bought a cd482 for HK$200, about US$25. Which is using CDM4/19 (Not Bad), SAA7210 ( Non-OS !!! in default) and the TDA1543 DAC chip. 
1) I just cut 4 legs (3 output and the PS pin) of the TDA1543 from the PCB, raise it to 8V supply and connect it directly to a Passive I/V.
2) Added a Minimalist clock as per LT1016 spec. sheet.

3)Damped the CDM4 with blue tak.
4) Added Sanyo OS-Cons all over the place.
Now it sounds soooooooooooOOO good !!! Very very good indeed for US$40 !! I can't believe it
