Speaker cable recommendation ?

I'm planning on buying new/used speaker cables. One of the cables are Nordost SPM's but I need 5m run's, so its too expensive. What are my choices within $1500 ~ $2000 ?

PS Audio HCA-2
Wadia 301
Audio Physic Tempo III
REL Strata
P-500 Pwr Regenarator

PSA power cables for amp, cd and P-500. Wadia is connected directly to HCA-2 with Nordost SPM XLR's.

Thanks a lot.
