Hello Popov - I would highly recommend two different cable sets for this system - either Audience AU24 or Purist Audio Design Aqueous Anniversary. Both would be very musical in this system and should provide years of long term satisfaction. I would not attempt to recommend power cords until you get the signal cables done and have an idea of what aspects of the system's sound oyu would want to bring out. Enjoy!
I agree with everything JWP said except I was going to recommend Purist Venustas (a little more expensive than Aqueous.)
