Yeah, seems so, forgot to clarify my home setup.
audio note az-2 speakers, noname(rather uknown name) 6x0.4mm silver litz speaker cable("bi-wired" by silver rods in speakers), 5m pretty generic usb cable to dac from dell precision laptop, an-c cable from dac to amp, pretty generic and short toslink cable from cd to dac, room has has more echo than it should, high ceilings, not much furniture, almost a cube.
Try to improve that before you worry about cables. Speaker placement, room treatment (furniture as well as acoustic treatment) and even a DSP can be the solution. No cable can change interference, resonance, frequencies that cancel each other out and so on...
