Balanced cable recom. for Classe

What is the best 1m balanced cable for Classe CA-151 amp/ Classe SSP-25 pre-amp/proces. My speakers are B&W804 Naut. My speaker cable is Purist Audio- My budget is $500.00 for the 1m pair. Thanks
I have good luck with balanced Harmonic tech truthlink between Classe ca200 and ssp-25
I am very happy with Goertz Micro Purl CU XLR's between a Classe DR5 pre and Sim Audio 4070.Sounds great,costs much less than $500.00.
