Which speaker cables for Ayre & JM Lab

Here is the system:

Interconnect are Siltech SQ-28G5 XLR
I also use a Hydra-2 (amplifier) and Hydra-4 (Cd and preamp) with Python Alpha.

Silver Audio Silver Symphony 48
Virtual Dynamics Master
Purist Audio design Venustas

What do you think ? Your suggestions are also welcome.
