Speaker cables for BAT - Dynaudio


Please suggest me suitable speaker cable for my DYNAUDIO FOCUS 260 Speakers.
Rest of my system are: Bryston BCD-1 > MIT AVT Proline Interconnects > Balanced Audio Technology VK3000SE Hybrid Integrated Amplifier > Acoustic Zen SATORI Speaker Cable.
I would like to spend within 600$ (Pre-owned).  
                                      Thanks in advance.

As per your advice I have purchased a pair of Adudioquest Colorado ICs from US Audio Mart through my friend.  Can you please suggest me a better power cable for BAT VK 3000SE?  Thanks in advance.
May you enjoy it in good health!
Regarding the power cable... AQ NRG-10, NRG-1000.. depending on your budget!
@gnanasekhar  I am currently using ZuMother power cords. They seem to be really nice but I have heard very good reports of Cerious Technology Graphene Extreme Power Cords from some long time audiogonners.
