NHT PVC PRO
I just acquired an NHT PVC Pro being used between my DAC and power amp; wondering what you recommend: short cables from DAC to PVC and long cables from PVC to power amp or vice versa? I have a half meter pair and a three meter pair of cables. Or does it really matter, since all balanced cables? Thanks in advance. BTW it sounds incredible (thanks for the recommendation Bob)
