What interconnects with Electrocompaniet

What cable interconnects and speakers are better suited for a bunch of Electrocompaniet ECI5 MKII and Electrocompaniet PD 1 and M2Tech Evo with speakers PMC PB1i ......
Choose Your so far between:

 
Transparent Ultra interlink XL
KUBALA-SOSNA EXPRESSION
Nordost Frey
Cardas Golden Reference

Around this price range Mauger there is something better, you can rasmotret as an option.
I want to achieve well-defined bass, a much greater speed and transparency, more open and airy high frequencies, much better imaging and soundstage.
