John Dunlavy On "Cable Nonsense"

Isn't it interesting that Dunlavy sells there own speaker cable for $480/ 8' and yet he claims it sounds no better that $10/ 8' Rat Shack wire?

We should all remember John Dunlavy forgot more about speaker design yesterday than we ever knew. The problem is he seams to be forgetting alot at a very alarming rate! (If you know what I mean) I just spoke with him again two weeks ago, and I still don't have a clue as to what we talked about. I'm not sure old John will be hanging around the plant too much longer, maybe a buy-out is on the horizon.

When I worked at Garland Audio in San Jose, CA, back in 1978, speaker designer Robert Fulton (the massive Fulton "J" was one of his products) walked in with an armload of what looked like suspension cable pilfered from the Golden Gate Bridge. "Where's the fire, Bob?" laughed owner John Garland, eliciting a frown from Fulton.

Fulton went into the sound room and, without so much as a "by your leave," replaced--after some gnashed-teeth grunting--the 12-gauge cable running from an ARC amp to a pair of Maggie Tympani ID's with his "Fulton Gold." Then he put a record on. Within 30 seconds, there was no more laughter, not from Garland, not from any of the rest of his sales staff, including yours truly.

I still hear differences in cable (sometimes for the better, sometimes for the worse). And when I read treatises that say they can't exist I'm reminded that from an aerodynamics perspective the bumblebee can't fly, either.

It is interesting that two well - established audio engineers and designers such as John Dunlavy and Frank Van Alstine appear to disregard much of the claims of cable manufacturers. However, both of these gentlemen do admit to there being some audible difference in some cables. I think that what Mr. Dunlavy is objecting to is the outrageous and irrational claims made by some cable manufacturers (whereas Mr. Van ALstine objects mainly to the prices charged).
An interesting addittion to this discussion can be found at John Risch's DIY cable web site (at www.audioasylum.com under "FAQ"). The subjective blind and double blind tests that he conducted found that the best SOUNDING cable also had the best scientific measurements - subjectivity backed up by science! It would seem that a good starting point, then, might be to build his best DIY cable, and use it as a reference when comparing cables in your system.

Most Audiophiles would probably agree that somewhere between 60 and 90 percent of the cable manufacturers have technology based on snake oil and other magic potions. The problem is we (at least I) don't know which 90 percent. There are a few that I do know use sound physical measurements along with listening tests. John Dunlavy has apparently taken it on himself to conduct an independent survey (tests) of a variety of cables. I really wish he would publish this, so that we can see, not from opinionated and potentially biased listening tests, but from independent measurements. That's not say that some people won't find that brand X with high capacitance doesn't work well in their system. As Mr. Dunlavy pointed out, equipment problems are sometimes rectified (or covered up) by cable design. It would be very interesting just to get the facts from that survey--then we might be able to better draw our own conclusions.

John Dunlavy's reputation notwithstanding, the proof is in what I hear, and I hear a difference. I would not consider myself a "Golden Ear", nor are all others that have experienced the same noticeable differences between various manufacturers' interconnects and (to a lesser extent) speaker cables in my system. I would respectfully suggest that the "Food for Thought" is why a reputable speaker manufacturer (and Dunlavy is not alone here) and respected engineer opts to dispute many a persons listening experience, instead of attempting to find out why their experience isn’t supported by the measured data. Certainly the quest would be a noble one. The “Holy Grail” of audio? Perhaps not, but it could put an end to a lot of posts and flames here.
