Mcintosh 501 - Front -Left - Center B&W802D -Mcintosh 402- Rear B&W803D B&W Cables ?

Hello-

I have all this great gear that I have owned for 10 years, recently moved and setting up again for 20% theater 80% audio 

The current cables - connects are 

Alpha Core Goertz TQ-2 Slver

AG -2 Verocity 

Center Speker is on Transparent Music Wave Ultra

Any thoughts on improving this equipment with cabling ? 

Much appreciated
