    Would all cables sound alike under DBT test?...Probably not!
    Looking at the some of [exotic] cables marketed out there, one see why the answer to above question is that not all cables will sound the same under DBT testing protocol.

    For example, Silver speaker cables tend to be made of higher gauge [thinner] cables, or the silver Interconnect not having any Shields. If we compare them with standard speaker cable or ICs, one will probably note lower volume (especially in the bass area) for Silver, and higher noise or interference ratio for silver ICs.

    Or, MIT cables have a secret patented boxes on their cables that will probably manipulate frequency response of the cable, and make them sound different than other cables.

    And some cables are faulty by design such as Ribbon speaker cables that have excessive inductance (warm sound), or Silver/Teflon Interconnects that sound "bright" because of high frequency ringing due to undesirable properties of Teflon dielectric.

    So if we do a round up of cables that are out there in a credible DBT test, it should no be assumed automatically that all of them will sound the same :)

    Couldn't agree more. The question is why use cables to attenuate or add distorition to a stereo. Why not use an equalizer?

    No problemo. The "problemo" is that many like to go by the catch phrase "all cables [missing part] sound the same" but conveniently disregard the all important [missing part] that qualifies this, which is "of similar length, guage and construction".

    Now, wether the difference in length, gauge and construction is worth the tremendous disparity in price between the low end and the high end is another matter entirely. One might more logically question where the point of diminishing returns levels off, and this may not only be based on acoustic differences, although it really should be.

    I pointed out on another thread that comparing cables to each other makes no sense at all and all such tests are invalid. They should be compared to an ideal shunt, as close to one as you can get, or put in a circuit which includes a duplicate shunt. The difference between the cable and the shunt is the magnitude and nature of the distortion of the cable. It should be pointed out that the same cable can give different results when being connected to different equipment. Therefore recommendations based on the results in one sound system may not be relevant to the results you would get with a different sound system.

    Equalizers are practically being given away at eBay auctions.

Depreciation from the price when new may be the worst of any audio gear. Do you have any thoughts on the lack of demand for used equalizers?

    Greenhill already demonstrated that some cables do sound different and it is not a mistery why.

    MIT has no secret components. It is patented and stated. It is for RF not audio.

    I'd like to see the high frequency ringing from a teflon cable.

    Ribbon cables have very high capacitance and very low inductance. Some amps go into oscilation with high capacitance. That si not a wiare fault but an amp fault. Poor design as others can handle it.

    So, the answer is rather simple, 12 ga to 16 ga. :D

    After reading these articles, I think I see why equalizers are so cheap on eBay. My guess is many users are disappointed with results from these devices, and may see them as a hifi liability. After looking at several on eBay, however, I can see how the meter readers might go ga ga over these things. A person could spend many pleasureable evenings making adjustment after adjustment to all those controls.

    I have to confess, the gadget lover in me was attracted to a couple of remote-controlled equalizers on auction, particularily a Sansui with a remote that could be hidden inside the cabinet ( at $50 "Buy Now," but no takers). This unit might be worth $30 to me, considering it's entertainment value, and how it would impress my non-audiophile friends, who don't even notice my cables.

    P.S. If I end up buying one of these things, I think it's only fair that I send Beckman the bill for having brought up the subject.

    Well...
    ...I have no idea why equalizers don't seem to have a market...perhaps, most of them are cheaply-made, with the ability to screw things up more than fix them...less than octave-width, which really renders them glorified tone controls...misunderstanding their abilities and incorrect use by consumers may also have given them a bad rap...outright misuse is fairly common; it would seem as though most users employ them as overall "gain devices" as opposed to equalizers...

    Now for the fun part...PCT, I'm not sure what sort of follow-up research you did re: your citations but, after reading them, off went all my buzzers and bells...the first two "white papers" were authored by people who would seem to have more than a passing interest in their respective organizations proprietary ideas and products. Both schemes seem aimed at the professional market and perhaps, at some future date, may filter down to the home audio enthusiast in a reasonable and reasonably priced form.

    The co-authors of the third reference are even more firmly entrenched in the marketing facet of the industry...one of them seems to have been, at various times: an electronic publisher, a media company director and even the editor and webmaster of the site cited itself(say THAT a few times)...other titles include: sales manager, manufacturers rep, marketing manager and director of sales. The other was named director of business development of a well-known name in pro audio apps, has held other "key sales and marketing positions", was VP of sales and marketing for another. regional sales manager and manufacturers rep for yet another.

    Hardly trying to denigrate these gentlemen's abilities in their respective fields of expertise, but I always have to take what certain folks say with a grain of salt...especially when they all seem to badmouth one thing in deference to something else they seem to have...er, shall we say...an "interest" in...

    "...A person could spend...
    ...many pleasureable evenings making adjustment after adjustment to all those controls..."

    Probably one of the misconceived reasons for purchase and why EQs have a low rep...

    For the most part, and when used as intended, EQs should be a "set it and forget it" component...even octave equalizers are difficult, if not impossible to set up by ear. Using program material further complicates the task...A calibrated source, such as a test disk or disc(media dependent) and an SPL meter are the minimal required tools. I've found graph paper, not just a little patience and an understanding spouse to also be invaluable. One must keep in mind, they do have limits and should be used judiciously, functioning as a frequency "equalizer" and not a "gain device"...

    Not that just "playing around" with 'em can't be useful however...it will give you some idea of the level of malarkey that abounds in "audiophile land" re: air and inner details and such...

    If you want to tweak a poor recording, simple tone controls are usually more than sufficient...that's of course if you have any!

    With the popularity of surround sound receivers that have equalizers built in there is no need for such devices in todays market for the average consumer. As for two channel audiophile's I think they look down upon anything that alters the sound of the music by attenuating the signal for a certain frequency range. I personaly have an integrated amplifier that does not have any equalizer controls on it and don't find that it needs them.

    My main argument to begin with was that any sound difference in an aftermarket cable over standard 12 gauge zip cord can only be caused from an attenuation in the signal over some part of the audio frequency range (usualy higher frequwncies giving a warm sound to the music). So why spend large sums of money on what is basicly a passive crossover when one could purchase an equalizer for $50 on ebay and have an active crossover?

    I think the answer has a lot to do with the audiophile crowd that feels the more you spend the better the sound, and don't know anything about signals, systems, Laplace transforms and electric & magnetic fields.

    If I had $2000 to improve the sound of a high end stereo I would look towards room treatments.

Little do they realize that passive cables will manipulate the signal more than active component such as EQ does. And the worst part is that if cables doesn't work out for you, you can not change its setting :)

    The proper use of an equalizer to enhance the sound of a home audio system almost certainly is beyond the capabilities of most audiophiles. The home use consumer type spectrum analyzers, noise generators, and microphones doesn't give satisfactory results based on my experience with them. It takes a well trained ear familiar with the sound of live unamplified music and extraordinary patience. It normally takes me about two years to adjust one to my satisfaction after everything else has been optimized. However, after a mere two months, I am making surprising progress on my Bose 901 enhancement project. The real problem of the moment is getting the bass right. That's often tough.

    While a 10 band equalizer doesn't offer nearly the precision or flexibility of a 27 or 30 band equalizer, what it can offer is substantial improvement. It seems to me that a 30 band equalizer or a parametric equalizer would require the use of professional grade measuring equipment and a technician experienced in using it. It's simply mind boggling imagining trying to get results by ear with something that complicated.

    Gene stated that a specific ribbon cable in his faceoff had lowest capacitance of those measured.

    I do not recall him generalizing to all ribbons.

    Without going to a coaxial system to constrain the magnetic field, flat, wide conductor ribbons separated by the insulation, placed face to face, will have higher capacitance and lower inductance. If they are placed edge to edge, they will have low capacitance and high inductance. The same if they are face to face, but are far apart..

    Ribbons that are multiple wires, alternating, will be somewhere in the middle..

    But the generalization that all ribbons are (one or the other) cannot be made..organization of the conductors will still play a large role.

    PS..yah, I really do agree with you...an eq in the hands of some is a weapon of masked destruction..

    Well I'm happy with Behringer FB1502 15-band equaliser. It's only $120 which is much cheaper than those exotic cables. :)

    "I have found it to be a trivial matter to setup and use my two channel 11 band eq.. Trivial enough, in fact, that my 9 and 11 year old children can also use it.."

    Apparantly that is why you get results that are so trivial that you prefer to bypass it. I think that proves my point. Even if you suspend your disbelief that this can actually be a useful tool in a fine home audio system, getting real benefit from it takes more than a trivial effort. Most people give up long before they even start down the right road so what you say is hardly surprising to me.

    If you ever decide to make any serious attempt to use it. Why not first listen to a lot of unamplified live music, then set all of the controls for flat, and then adjusting only one or two controls very cautiously, see if you can get just a minor improvement for a start. Don't do anything else for weeks until you are convinced that the change is for the better not for the worse. Then satisfy yourself with just a small improvement each time taking days or weeks to decide if the last change was for the better or the worse. Reitterate this until you are just about nuts and you'll get some idea of why I say it is a long slow patient process. Any attempt to fix every problem at once is doomed.

    Still smoking the weed Phil?

    " Contact your Dealer for specific questions on cable choices."

    C'mon Phil, who are you and this guy Wilson kidding. Whatever dealer you call will say that while there are many good products on the market (rarely will knock someone elses product) the brands he carries are the best ones to buy for the money in each price category. As for quality, he'll tell you there's good, better, and best which by some strange conincidence happen to coincide exactly with expensive, expensiver, and expensivest.

    What are "network" cables? More made up technobabble to further confuse the already confused no doubt.

    BTW, why do you bother to tell this to us "peasants" who shop only at Best Buy or Circuit City anyway. Aren't we beneath you ....Lord of the Tower?

    "...Contact your Dealer for specific questions on cable choices."

    Which in essence translates to "write us a blank check" or "give us your bank account's PIN"...

    Sorry, fella'...I've said it before and I'ma gonna' say it agin...most salesmen are equally adept at selling refrigerators as they are audio equipment; they know little about either...wouldn't know the diff between wire and cable...they push what the boss tells 'em to. I've met a few who were conversant enough to provide half-decent opinions and recs, but for the most part they were few and far between...and the same goes for cars, storm windows, toaster-ovens...yada, yada yada...ad infinitum...

    Hello Beckman

    There are a couple of nice EQ's I can think of being Urei 539 and White Instruments. 1/3 octave cut only. Low noise very nice units. Then you have parametrics with give you more flexabillity. But you have to know who to use them.

    I knew a few high-end manufacturers were in Utah(e.g., Wilson, Sound Lab, Zu). There probably are others. Maybe they are not all LDS -- some may be refugees from the Golden State.

    I may be missing something, but are people here saying they adjust equalizers by ear under sighted listening conditions? If so, are some of them the same guys who say sighted listening is unreliable?

    "...adjust equalizers by ear..."
    ...a fool's errand IMHO...

    ...as I outlined in my response to your post yesterday...and which I take the liberty of re-posting here:

    ...many pleasureable evenings making adjustment after adjustment to all those controls..."

    Probably one of the misconceived reasons for purchase and why EQs have a low rep...

    For the most part, and when used as intended, EQs should be a "set it and forget it" component...even octave equalizers are difficult, if not impossible to set up by ear. Using program material further complicates the task...A calibrated source, such as a test disk or disc(media dependent) and an SPL meter are the minimal required tools. I've found graph paper, not just a little patience and an understanding spouse to also be invaluable. One must keep in mind, they do have limits and should be used judiciously, functioning as a frequency "equalizer" and not a "gain device"...

    Not that just "playing around" with 'em can't be useful however...it will give you some idea of the level of malarkey that abounds in "audiophile land" re: air and inner details and such...

    If you want to tweak a poor recording, simple tone controls are usually more than sufficient...that's of course if you have any!

    I think skeptic said he did it by ear. I wasn't sure about everyone's description of what they did, which Is why I prefaced my question with a "I may be missing something."

    Anyway, not having used an equalizer, I'm not sure I understand the procedure. How do you know the equalizer is needed to begin with, if not by using your ears,and how do you know you adjusted the equalizer right, if not by using yours ears? And if you listen, is it blinded or sighted listening?

    I can't believe it. Here we've been talking about equalizers and I totally forgot I've got two in my system - one per channel. My Vandy 5s use an 11-band equalizer on the self-powered subwoofers. Richard Vandersteen personally set mine using just a Stereophile CD and
    my Rat Shack sound thingy.

    Result: just about the cleanest, most extended bass I've ever heard in a system.

    I tend to forget the equalizers are even there. Once set, I never felt the need to go back and tinker.

    Absolutly correct. However, if you knock out a wall in your listening room, raise the ceiling, go from carpet to hardwood, etc., you might want to invite Richard Vandersteen back for a beer and a tweak.

    The only time you really don't need an equalizer is when you have an acoustically perfect room with a flat response from 20-20000 Hz. So really, everybody needs one if you want to get technical. And I would venture to guess that a combination of room acoustics and proper equalization would make anyone completely forget about cables.

    I'm no acoustic expert but I would guess that what is needed is a frequency response map of the listening room and then a plan to correct frequency fluctuations with the equalizer. Depending on the dimensions, shape and content of the room, some frequencies will likely resonate which is usually undesirable. Then you would re-measure and see if it is flat yet (flat is the goal). When you are done you can do a blind comparision between equalizer bypass and the new settings to see if you prefer them.

    I would suspect you would need some fairly sophisticated equipment to map the frequency response of a room.

    In the end, the difficult part is that some or most people either don't like a flat response or have never really heard a true one so it might sound odd.

    These are just ramblings so take them with a grain of salt.

    You want to get the response in room as good as you can with placement and room treatments. Then you use cut only EQ's as icing on the cake. You map across your primary listening positions with an RTA and go from there. By ear won't work you need a pink noise source and a good measurement device. You can get computer based RTA software for not much money and a measurement mike for around $50 from Behringer. Just need a phantom power source for the mic and you can go right into your sound card. Takes a while to get it all set-up for a final curve but it's worth it.
