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 far as I’m concerned, AudioQuest cables have an excellent synergy with both BAT and Dynaudio. I’ve listened to Contour 1.3SE, 1.4 and Focus 160 in my system with Mont Blanc, Volcano and Everest speaker cables from AQ. I recommend the Volcano if you find a good deal.
This is my system:
Triangle Magellan Cello II < AudioQuest Everest DBS 72V < BAT VK-600SE < AudioQuest NRG WEL DBS 72V < AudioQuest WBY XLR DBS 72V < exaSound e22 DAC w Paul Hynes SR3-12 Power Supply < Squeezelite w Logitech Media Server < UpTone ISO Regen < AudioQuest Diamond USB DBS 216V < MacBook Pro i5 13’ w Samsung 850EVO 512GB SSD < Omicron Harmonic Stabilizer & Gold SE/Classic < IsoTek Sigmas GII w IsoTek Optimum EVO3 < Furutech FT-SWS < HiFi Tuning Supreme 3 < Solid Tech Hybrid
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.
