Power Cord & SPDIF Coaxial Recommendations For Audiomeca Mephisto CD Transport

Hi
i have a Calif Audio lab Icon Mk 11
CD player with both digital and analog outputs

in my pre amp section of my Peachtree 150 there is only a single coax input
question-
should I use the coax or the analog input?
I have a Cambridge CXN V2 streamer that has coax ,analog and optical outputs 
Which output from the streamer should I be using ?
my initial thought is CD to analog since it can’t go beyond 44.1khz and coax for the streamer????? Or optical ?  
thx

Has anyone tried Blue Jeans Cable?
ive used them for several years
not costly but nice sound transfer 

How much air space is needed above a Class D integrated amp?

We make this, and it’s very highly regarded.
