iasi,
Many skeptics would not say that cables have an impact on sound quality...but not necessarily in the ways many audiophiles believe. That is: a basic, well designed cable, properly chosen for the job at hand (e.g. capacitance etc for a given length/job)...is essentially transparent. That is, it's not the case that any time you change a cable the sound ought to change because "all cables 'sound' different."
But, yes, choose the wrong cable for the job and you can get something like a tone control (e.g. rolling off the high end), so in that sense cables can sound different.
That caveat out of the way.
I have often pointed out that audiophiles swooning over the 'sound' of their latest expensive cable purchase are simultaneously swooning over the sound of the relatively basic, cheap, industry-grade cables used to create most of the recordings we listen to.
