Usuthu open their competition account against Free State Stars at Goble Park on Saturday.
"I remember winning the TKO in my first season in the PSL with Stars and it was a great feeling," Kapini told his club's official website.
"Once you experience that feeling, you can’t let it go.
"It would be such an honour for me to lift the cup as captain of AmaZulu because this club deserves to have silverware in the cabinet."
The Zimbabwean is confident new signings Sthembiso Ngcobo and Letladi Madubanya can help their side's cause, with the duo also claiming TKO honours with other outfits.
"Having players who know what it means to reach a cup final, to play in front of a packed stadium and to lift the trophy at the end is good for the team," Kapini said.
"The whole team is hungry for success and hopeful it will show on the field of play."
Regarding facing Ea Lla Koto, he said: "We’ll be playing away from home but we have to show our character and continue playing our style of attacking football.
"We have done well away from home in the League and we’ll try to continue with the same form.
"It’s going to be a tough game but we have to use our chances and avoid making mistakes at the back."
AmaZulu are joint-top of the Premiership standings with 11 points from six matches - three points ahead of their upcoming opponents, who have played a game less.
