how to modify my cdp to accept new power cord

You might want to check with Pierre Sprey at Mapleshaderecords.com who sells a splice-on PC upgrade using the remaining tail.
He feels this yields audible improvement that beats using the more traditional IEC modification.
I like the performance of his power cords, but have never used this particular splice-on power cord variation.

I would start w/the splice, which can be found here or better yet, at your local electrical supply house.

If that sounds like an improvement, then go for the IEC installed on the chassis.

Why do you want to do this? Sounds like a lot of trouble for minimal gain. Just my opinion.

Add the IEC socket. I have done this on several pieces of gear. works well. Scribe the outline of the socket on the back panel of your CDP. Then use a dremel tool with a cut off wheel to cut through the chassis. If you can remove the back panel from the CDP first, that would be a better option, since it would lessen the chance for metal particles getting into your drive or PCBs.

i believe there is a big difference in what cords you use too feed gear. i recently lost all sounstage and 3d effect. i couldnt think of anything i had changed. well i remembered that i had swapped out the power cord feeding my tube preamp. it was a bit loose at the gear. i used an extra cord thinking it wouldnt make a difference. haha that was a mistake. i put the old one back in place and the sound i was missing was back. this was to my preamp which would be less important than my cdp. the guage wire was larger and i never noticed till i put it back in. made a big change. i am getting my parts tomorrow so please monitor this post if possible johnss. your time is appreciated kevin
