Default Modifying the NAD C521BEE

This project is a work in progress. Some pics of what I've done so far:

Reinforced the disc-clamping bridge with epoxy.




Added dynamat to transport frame, laser assembly, drive motor, main chassis, and top cover.




Added a pair of Mundorf 10uF M-Cap's bypassed with WIMA 0.22uF in each channel for output caps.






Installed an IEC jack and 12ga power wire. The hole came out a bit rough and I scratched the case a few times with the file , but it works.








Eventually I plan on getting a few different op-amps to roll, installing some nicer RCA jacks, replacing all the electrolytic caps with Rubycon ZL series, and changing the S/PDIF out from a RCA to a BNC jack. I don't want to go overboard modding this player since I'm saving the good stuff for a DIY DAC, probably something like the DDDAC1543 MK2.
