Not touching the cable debate with a ten foot pole, all I'll say is going from a stock USB cable to a LH labs 1G made a major jump in SQ in my system. You will hear different opinions from both sides, but IMO there's no point spending $400 on an amp and or $250 on DAC and using $5 cables since a system is only as good as its weakest link. In my experience I did not hear how good my system really was until I ditched cheap cables and realized they were a bottleneck. And you don't need uber expensive cables either, I would just avoid the cheap stuff. YMMV, IMO, etc etc
