Cables etc are a source of many a cyclical argument.... Which I'm sure we don't want to repeat so I'll leave my input on the matter thus...
Most people believe them to have an effect on the sound, ranging from n'th degree to big differences...
Not everyone agrees though. I*, and a significant minority of others, believe them to have no real effect on sound beyond those fairly rare cases in which the inductance, resistance and capacitance actually come into play in any meaningful way at audio frequencies. High capacitance speaker cable being an exception in that certain amplifiers (all solid state) which have not been properly designed to be unconditionally stable can be sent into ultrasonic oscillation and may blow up....
* I believe I am sort of required by "the management" to put a disclaimer along the lines of "just because I'm an Electronic Engineer with decades of experience in designing hi fi equipment, as well as being an audiophile, doesn't mean you should listen to anything I say on the subject of cables as I am a heretic and blasphemer" Other opinions are available and YMMV
