Interconnect cable upgrade disapointment


I have recently upgraded my Audioquest Topaz XLR interconnects from my amp to preamp and from my preamp to my CD player with Audioquest Cobra XLRs. I was expecting to hear a substantial difference based on the significant price difference between these cables but I hardly noticed any difference at all. If I need to break in the interconnects to have an apples to apples comparison I would appreciate tips on how to do so. Currently, I have a CD playing on repeat. How long will the break in period take and can I expect to observe a substantial difference? Your help would be greatly appreciated.

Blindjim - the handle comes from the title of a book written fairly recently about 20th century 'classical' music "The Rest is Noise" which happened to be in front of me on the bookshelf when I selected my moniker for this forum.

Additionally - one thing I would like to point out - although not directed toward Blindjim but to the comments from another poster about reducing vibration - my goal with vibration reduction is not to improve sound quality - what prompted my interest, aside from inefficiencies, is I do not want to "feel" the music when I listen with my feet on the floor. If you look further down my post with regard to vibration damping you will see some reference to that effect, which occurs when at high volumes. To the extent that I can get rid of that effect, is the purpose for the damping system. I don't expect a change in quality of the sound from the damping of the floor-speaker effect.
"Seems like I have touched a nerve - do I detect one with a pecuniary interest in cables? And no, I won't be joining you on the cable adventure - I have heard the cable argument for going on 20 years and it is as meritless today as it was 20 years ago."

You're right, you touched a nerve; I think you've got a lot of nerve making pronouncements when you seemingly have done nothing to test it out. Then, in arrogance dismiss the reports of those who have done comparisons. You really think your logic is wonderful. I know, I used to be just like you.

I think in this post you reveal your true motivation: Mistrust

No, you do not detect, "one with a pecuniary interest in cables," as you are speaking with someone who conducted tests with suites of cables on his own dime - sometimes tying up $4-5K in extra cables for comparisons, then to sell them off -years before becoming a reviewer. Sorry, wrong assumption on your part, but it confirms the deep suspicion and mistrust that lies underneath your dismissal of cables.

I became convinced of my perspective on cables before I had any part in reviewing. In fact, it was all my informal comparisons of suites of cables which led me to conduct three reviews of cable groupings quickly after becoming a reviewer. I wanted to conduct more listening tests to confirm what I had found on my own. Reviewing has only strenghened the conclusions I already reached. I have had more access to cables from all levels of quality and different brands. My conclusion about the efficacy of cables is verified on a weekly basis, and witnessed by audiophiles whom I invite into my room. So, yes, it gets tiresome to hear someone with almost zero experience act like they know it all in regards to what cables can/can't do.

Why the suspicion simply because I mention that I review? You don't believe people when they're sharing experiences? You think there's always a fiscal (almost an evil audiophile) ulterior motive? Pretty sad. At least those who are not so jaded can learn something here.

I wish you well in your isolation device endeavor. :)
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.
Musicnoise, you said, "As to comparing cables by listening to them, I cannot say that I have extensively engaged in that practice..."

My point exactly. Thank you for clarifying.
Seems like the original poster has already gone down the path of depending on someone else's subjective listening experience - the result is reflected in the subject line of the thread "interconnect cable upgrade dissapointment" - I doubt that he or she will make that same mistake twice.
