which male RCA is the best interm of SQ and easy t

I have one Stereovox Draco 2.4 m and would like to reterminate into 3 pairs. I wonder which RCA connectors to be use to get the best sound quality, price and easy to use and assemble (all these have similar prices)
1. Eichmann Silver
2. WBT nextgen
3. Vampire Wire 800
4. Furutech FP 106(R) or 120 (R)
does the size of the cable have effedt on chooseing RCA connector because usually it accept up to 9.3 mm cable diameter except Furutech FP120(R) may accet 12.3mm cable. If we use bigger connector with smaller cable will there be a problem
thanks
