They're all 20 bit colinear chips and not 18 bit as I read here. I wouldn't use PCM63K in piggyback configuration, for financial as well as for technical reasons.
Please use desolder braid and give up the thought that the old PCM's will survive the desoldering. They are sensitive I can tell you. Clean the board with alcohol and a cotton cloth afterwards while wearing an antistatic band around the wrist that's connected with ground/earth. Make sure you clean again with a dry cotton cloth.
Ok so I want to know if the newer (and AVAILABLE unlike the other one), PCM1704K DAC will work? Or would it require further modification to work?

Put an LCaudio clock in,
replaced tre coupling caps with film caps,
We both like the player.
Months later we replaced the PCM63's with K grade, but that was a minor improvement IMHO.
