The Best AC/ IEC power plug combination. Oyaide, Iego, Neotech

I am looking for the best AC/ IEC plug combination to be used with a solid core copper/ OCC cable.

I found that the sound is significantly influenced by the power plugs, in some cases even more so than the cable itself.

Right now I have "the best" plugs, namely Oyaide M1/ F1 plugs on my powercables,

They are nothing short of amazing, however.

They add soundstage, width, depth, seperation, openess, precision. However, they also lose on timbre and warmth/ emotion.

Now I am looking at other combinations within my chain.

Could you share some light on the following:

Neotech AC - Neotech IEC
Iego AC - Iego IEC
Oyaide with either Neotech or Iego on the other side
or even
Neotech on side and Iego other side

Which plug influences the sound more, the IEC or AC plug?

I was thinking of getting Rhodium copper/ silver AC side and Gold IEC side, basically receiving all the detail and resolution first and then adding a touch of warmth.

Or should I approach it the other way around?

Thanks.
