@Andrein @PENG Thats a good suggestion. I am flexible about the receiver. I went for Yamaha, just because i have been using one for last few years. Denon seems reasonable as long as i have the flexibility to expand in future.
bluejeans cable seems awesome - seems like we have that in uk now. so these are the choices they have
TypeBJC Ten White (5T00UP) (White jacket, 10 AWG)
Belden 5T00UP (Gray jacket, 10 AWG)
BJC Twelve White (5000UE) (White jacket, 12 AWG)
Belden 5000UE (Gray jacket, 12 AWG)
Canare 4S11 (Star Quad cable, 14 AWG)
So i would assume Canare 4S11 for the long runs and Belden 5000UE for the short ones?
