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.

After living with either mostly or all BAT systems for over 13 years, and using many different cables, I preferred the Audioquest the best. The Mont Blanc speaker cables are very good and would probably be in your budget used. 
I just recently upgraded from a pair of van den hul mcd352 to a set of analysis plus oval 9 cables from my bat vk600se to wilson witt and was pleasantly surprised by an increase in field of depth and tightning of the mid and upper bass in particular. Piano and acoustic guitar seem much more focussed
