Vitus Sia-025 Power Cable Recommendations

Dear all. Just wondering whether I could get some friendly advice. I have been using an old acrolink4030 to power the sia-025 for the longest time, but recently decided to try something different. That was when I realised that the amp is actually really sensitive to cable changes. I have tried the Shunyata ZiTron Anacoda, ByBee Power Cables, High Fidelity CT1 Reference and several others, with the ByBee being my favourite so far. Does anyone else out there have any suggestions on some other cables I could try? 

Thanks!
