I thought I would take a second to correct some of the last poster's inaccuracies, for the benefit of the original poster, so that the original poster can evaluate the recommendations to the extent that future choices are made. As to experience and training, I built my first ham radio and put up my first tower decades ago as a teenage. In other words I have been connecting parts of electronic systems for a long time with great success. I learned more than a bit about electronics from years as an amateur radio operator, from repairing aviation weapons control systems and radar in the USN, from an undergraduate degree in electrical engineering, from decades working as a biomedical engineer in research designs and clinical applications, decades as a member of the IEEE, and many years teaching electronics both in the classroom and in the laboratory at a technical college part time in the evenings.
Amplifiers are amplifiers, frequency response is frequency response, interconnects between equipment do not 'know' what the signal is - whether it represents music, a nerve conduction potential, or the output of a radar receiver, is immaterial to the interconnecting cable. What is important in determining selections in such interconnections is an understanding of the frequency and time domain characteristics of the signal and the electrical properties of the interconnected devices. In other words, there is nothing particularly special about moving signals around in a an audio system. So, I present my opinion in these matters from a considerable background pertinent to the topic. As to comparing cables by listening to them, I cannot say that I have extensively engaged in that practice, - however, there simply isn't a lot of value to be assigned to such subjective unquantifiable endeavors, if there were we would likely see a large number of studies of the results published in professional journals.
As a sidelight, a trademark of a weak argument is the ad hominem attack. A trademark of a weak argument in a scientific or technical area is the extent to which the opinion relies on subjectivity without objective findings, relies on other than logic, and is presented in emotional terms, as these are of no relevance to technical subjects. When the original poster decides what probative weight to assign to the various opinions, he or she may wish to take into consideration these factors.
