John Dunlavy On "Cable Nonsense"


Food for thought...

I'll admit that there must be some placebo effect in cabling. I will also admit that there is an audible difference too. For me to tell you all improvements heard are factual is as crazy as those who claim it's all psychological. As many of you know, I have strong beliefs in power cord benefits and have written extensively on my testing. I've started a new mission to try different Interconnects and speaker wires. I will be receiving two pair of the flagship model of hideously expensive speaker wires this week that I bought for 1/10th of the retail price. I also have five different brands of Interconnects on the way. If I end up with these speaker cables, the retail cost of my system will double. That can not be justifiable right? I'll let you know. What I can tell you is power cords alone have allowed me to hear things (the foot pedal on piano as an example) that are simply not audible with stock cords. I need no "blind" testing, it's factually there or not there. If anyone wants to argue that point, please save the effort, I will not acknowledge your short sighted opinion. For me to assume anything but improvement from higher quality speaker wire and interconnects, given my experience with power cords would be hard. If a power cord can qualitatively make an audible difference, then I must assume cables will to. Like I say, I'll let you know. As always I'll be using my blindfold testing with my buddies. Yes this is the "unapproved and non-accredited" by the great AudiogoN science community test, but it's the one I have always used.
It's interesting to note that these speaker cables are copper! I've been a real fan of silver over the years, but remain open to experimenting with other materials. It's been stated in a number of reviews that the lower price siblings of these cables are capable of being more revealing than the silver cables they were compared to. I find it difficult to believe that the reviewers have too much political motivation in that these cables are rarely advertised and not a part of any magazines "top" lists. Just simple marketing and hideous pricing. I will refrain from giving out the brand to try and keep my review as un-bias to the reader as possible. Stay tuned, it should be fun! J.D.
Sqjudge, knowing you from our off air conversations I'll bet your loving Liguy's post. Hey Li... you have no idea!!!!!!!!!!!!!! P.S. Sqjudge, I've been working on a return message, I'll get it off soon. J.D.
Steve, My "Placebo Effect" is in reverse. When I try Radio Shack cables vs multi kilobuck ICs I am praying and rooting real hard that Radio Shack wins the contest. I dont like paying the same price for an IC as an amplifier.It goes against my sense of what is fair and honest. On the other hand, who am I to say to a design engineer that the last five years of testing, scrapping, midnight oil burning,and cost etc.,does'nt warrent the price?
BTW, I have also heard many exotic speaker wires screw up the sound far worse than stranded zip cord. Getting zip cord to sound correct though, is not the way Monster or Sound Connections or the old Levinson company did it. They used too many strands to achieve a given guage and wound up with mud sonically. (here come the morter shells)
Paul, I also concur with your last paragraph......Frank
Liguy, I commented on the idea of "transmission line" theory applying to audio frequencys. I do not dispute the charterisic impedance of a cable even if it is only a centimeter in length. Do you happen to recall how long an IC would have to be to get even ONE standing wave in it at any audio frequency? (it is way more than a few feet)
Here's my 2 cents worth...
First off let me say that I am a believer in that cables do make a difference (not always for the good) and that bi-wiring also makes a difference (also not always to the plus side of things).
This past weekend I spent some time with a pair of cable designers who I have come to know over the last 5 months. These guys make cables that have separate cables for transmit and returns as opposed to all cables being in the same jacket - typical stereo cables are 2 cables per channel and bi-wires are 4 cables per channel. We tested a prototype cable (bi-wire version) that was constructed in a different configuration in that the return wires were made slightly different in terms of the internal wrapping of the materials. The transmit wires were configured exactly the same. Using the same system (older but high end Sony cdp, Copeland preamp and amp) but using three different pairs of speakers (Duntech, B&W 803 S2 and a pair of DIY (vifa & seas drivers) I was able to tell each and every time when the return wires had been changed. I found what can best be described as an "aggressive" verus a "laid-back" sound when the cables were swapped. There were about 6 listeners there and we all were able to distinguish the differences although personal tastes lent to a discussion on which way sounded best. Some times I preferred the "laid-back" version while others preferred the other.

In a nutshell it can be said that I am a believer in cable differences but respect the right of those who believe that they don't make difference from a purely scientific standpoint or have tried but have noticed no difference. I am no electrical engineer but do have a background in ultrasonics (so I have some knowledge on how sound and electrical signals move through time and space) but it was my experience that there was a significant difference each time, audible to a number of people - I can't explain it scientifically but I know what I heard and the only thing our group of testers could not definatively agree on was which version sounded the best.

I am glad for the differences expressed in these forums as it allows for one's own experiences to be be heard (read) and it would truly be a boring world (audio and otherwise) if we all were of the same opinion...
