Keith Eichmann HC-XTC Phono Pod vs WBT NextGen RCA

I have the old version WBT-0101 RCA plug (NOT NextGen) for my interconnect.
And now, I have purchased some Eichmann Copper Bullet Plug after reading some good review.

Now I am interested to change my RCA socket.

Who has compare this NEW "Keith Eichmann designed HC-XTC Phono Pod" to any WBT NextGen RCA socket?

My system is copper.

You may elaborate and share. Thanks.
