A Review Of Audioquest Volcano 72 Volt DBS Speaker Cable

Introduction

I have been intrigued by Audioquest’s DBS (dielectric bias system) cables for a few years. I even went so far as to go the US Patent Office website and study AQ’s patent application and design drawings for the DBS. Although the technology made sense to me, and I had read some favorable reviews of AQ’s DBS cables, I was always put off by the high prices, both for new and used product. I have also noticed that, because of the high prices, these cables typically are difficult to resell (e.g. Audiogon, eBay). I like to experiment, but I don’t like to take a financial soaking while doing so.

I ran across a pair of older style Audioquest Volcano DBS speaker cables at what I considered to be an attractive price. The seller had upgraded to some (much more expensive) Siltech cables. I sent an email to AQ’s customer service asking about the performance differences between the older Volcano DBS cables with the red/black jacket and the latest model Volcanoes with the gray/black jacket. AQ replied the next day that the older version and current version Volcano cables are identical with regard to internal construction and performance. The only differences were in the jacket color and the thicker spade terminations on the new model. I was further advised that I could send the older cables back to AQ for retermination for $25 to cover labor and return shipping + the cost of the spades ($96). I really didn’t need the newer type spades, I just wanted them because they were prettier. I found the spades at a discount at an online retailer and attempted to install them myself. However, each of the Volcano’s internal solid core copper conductors is coated in a hard plastic sheath which is difficult to remove. I was concerned about damaging the wires, so the cables and spades were sent back to AQ for retermination. I received them back 11 days later. Most of that was transit time as AQ received the cables on a Wednesday and sent them back to me the following Friday.

All of my listening evaluations were done with the older spades. When I received the reterminated cables, I did not notice any sonic differences.

The Sound

The Volcanos are constructed of multigauge, individually insulated solid core copper wires with an aggregate cross sectional area of 9 gauge wire. The interested reader can find more details on the websites of AQ corporation and the US Patent Office. The manufacturer specifies a “break in” time of 150 hours before the cables reach peak performance with the DBS engaged.

I asked the seller to disconnect the DBS battery pack prior to shipping. He advised me that he had disconnected the battery packs prior to placing them in storage. I wanted to compare the sound of the cables with and without the DBS effect.

Figure 2. Each DBS battery pack contains six 12 volt type 23A batteries.

Figure 3. 12 volt type 23A battery.

Compared to the PS Audio xStream Resolution Reference cables I was using, the non-energized Volcanos offered the following improvements:

1. A little more bass definition.
2. More overall detail and clarity.
3. Much more low level detail. I first noticed this when vocal recordings were fading out at the end. I could hear everything much more clearly. I decided to test the Volcanos against some of my Marvin Gaye recordings. Marvin is notorious for mumbling and slurring his words while singing. I could make out every word with the Volcanos. I could even hear everything clearly if I stepped into the next room.

The soundstaging and imaging properties of the non-energized Volcanos were the same as the xStream Resolution Reference cables.

After 10 hours of play time with the DBS disconnected, I plugged in the battery packs, which placed a 72 volt charge across the cable dielectric insulating material. I immediately noticed a muddying of the bass and a veiling of the mid and high frequencies. This persisted for the next 24 hours of play time.

After 24 hours, the bass muddiness was gone and was replaced with even more definition and bass impact than heard in the non-energized state. There was more sustain and natural decay in piano notes and more three dimensionality in the soundstage.

I did not notice any more differences until nine days later. This was after my log showed 216 hours of play time had passed. I was astonished by what I heard. The soundstage width on each side was increased a couple of feet. The front of the soundstage was projected another couple of feet forward. There was a huge increase in dynamics and in the three-dimensionality and weight of images within the soundstage. The music was liquid and flowing with the xStreams. However, the music was more liquid and flowed with more force with the Volcanos. I liken it to the difference between water flowing down the Niagara river and water flowing forcefully over Niagara Falls.

After my listening evaluations were complete, the Volcanos were sent back to AQ for retermination and the PS Audio xStreams were reinstalled. The “fallback” in performance was very noticeable, but was not intolerable for the 11 days the Volcanos were gone.

Conclusion

The attached table summarizes my comparison of four cables (including the Volcanos) ranging in price from $32 per pair to $3300 per pair. I subjectively believe that the Volcanos were well worth what I paid, but I would not pay anywhere near their MSRP. I have noted that some audiophiles do not mind paying more for cables than they paid for the components on either or both ends of the cable. I'm not quite there yet.

Some years ago I came to the realization that, rather than being mere "wires", cables are components in their own right. Some serious thought should be given to evaluating and selecting cables with resolving power comparable to the components they are connected to. If you are willing to pay a "pretty penny" for gear capable of generating high resolution audio signals, it stands to reason that you may have to pay a commensurate "pretty penny" to maintain the integrity of those high resolution signals as they travel from source component to amplification to speaker.

I really do not understand some of the emotional responses that cables, especially expensive ones, elicit. It’s just wire, either it works for you or it does not. Even more perplexing to me is the view that there are no audible differences in cables and if there were, such differences could be measured. Such a view overlooks the fact that music signals, i.e. the electrical currents flowing through cables, interact with the cable’s conductors on an atomic and molecular level. Therefore, in most cases, unless you have equipment sensitive enough to measure phenomena at the atomic and molecular level, you will not be able to correlate sonic differences with a measured difference. I hope that one day a qualified "meter pontiff" with access to the appropriate equipment will do some comparative analysis of audio cables. Until then, I’ll get by with my trusty ears.

Such good sound.BeerChugSmiley.gif

    The AQ CV-8 w/ 72v BP did wonders to my sound stage and improved much of what you described w/ bass. On Focal's.

    I need to do a review similar to yours when I have then hooked up to the Tyler's. Congrat's on good sound brother!

    Nice review.

    Reminds me of when I changed from Harmonic Tech Pro-11 cables to Nordost Frey; as good as the HT cables were, the Nordost cables get out of the way and allow the music to flow. They also took about 500 hours (Simaudio components are powered on 24/7) to reveal their true nature and astonish me.
    All truth passes through three stages. First, it is ridiculed, second it is violently opposed and third, it is accepted as self evident.

    Ok...I don't really want to say this..but gee....batteries...this is pretty much a gimic. Just going only by what you said..when you put them in the sound was not so good...after x amount of days..it was better(batteries starting to die out).....then later ..even better...(batteries low).....once they get down to a certain level...basic cable. Your not dealing with burning in some tubes or something...you just waiting for the batteries to die out or get low. Just seems like a gimic to me....but hay .if it floats your boat and you like it.....good for you.

    The batteries did not die out after a few days. The battery charge lasts for years. The AQ website has a discussion of DBS technology if you are interested in learning more.

    I've had mine for years-the batteries are still good.
    Stop trying. Go buy a decent preamp, then report back.

    Nice review DQ as usual. I have a softspot for audioquest, an honest cable IMO.

    There's always the knockers out there, the people that just cant tell the difference. In the past i only ever heard subtle differences, and have since learned that the equipment is the key.

    Reference quality equipment makes it a night and day difference.
    In terms of audio, i truly feel sorry for the visually impaired. How can they know what they like if they cant read google?

    We understand that you believe that those of us who hear differences in cables are stupid, foolish, delusional, and suffering from chronic placebo effect. Why keep wasting your time on a lost cause? You are more enlightened than us. We get it, ok?

    I think smoking is a nasty, harmful habit. However, I do not feel compelled to get in the face of every smoker I see and tell them about the dangers of smoking. Nor do I feel superior to those who choose to smoke. My father smoked and I have friends who smoke. I don't consider them stupid for doing so. They are engaging in a practice that they find pleasurable and they are obviously willing to assume the risks of that practice...just like skydivers, extreme sports enthusiasts and people who eat too much pizza. Most of us have some bad habit that we would be better off not engaging in.

    There are lots of things in this hobby I find questionable...like "magic pebbles" for example. I don't understand how attaching a bag of rocks to your interconnects would improve the sound. However, just because this tweak does not appeal to me, I would never approach a magic pebbles user with:
    "Gee...you're putting bags of rocks on your interconnects, huh? What a crock of ****."

    No, for all I know, magic pebbles may be made from a special magnetic ore that absorbs a bit of high frequency noise. Even if the effect of magic pebbles is squarely in the realm of placebo, the user is getting a return on his investment via a perceived increase in his or her listening pleasure. I have no interest in disparaging them because of what they choose to play with.

    We realize that you, and others of your ilk, have once tried a more expensive cable and that you did not hear a difference in your particular system with your ears. This is useful information for someone with similar musical tastes and similar audio equipment and perhaps similar auditory response. I don't understand why you, and others of your ilk, feel that your limited experience is applicable to everyone else's audio scenario. It it good to share experiences, if the sharing is coming from good intentions. I have benefited immensely from those who have taken the time to document what did and didn't work for them in their audio trials.

    It may surprise you to know that sometimes, I, even I, don't hear a difference or improvement when going to a better cable or even to a "better" piece of gear. "Better" often depends on component resolution capability, system synergy, listening perceptions, and personal preferences. Some examples, which have been documented in more detail here on the forum, are:

    1. I replaced the stock power cable on my turntable motor power supply with a Signal Cable MagicPower cord ($74), A PS Audio Statement SC power Cord ($629), and A PS Audio Premier SC power cord ($1,793). Noise spectrum measurements taken with an oscilloscope confirmed that the Statement and Premier power cords filtered more noise from the power signal. I heard an improvement with the Signal Cable cord over the stock power cord. However, I perceived (heard) no difference between the Signal and two PS Audio cords in that particular application.

    2. In my two channel rig, I replaced the stock power cable on the PS Audio Power Plant Premier AC regenerator with a Signal Cable MagicPower cord ($74), A PS Audio Statement SC power Cord ($629), and A PS Audio Premier SC power cord ($1,793). I heard an improvement with the Signal Cable cord over the stock power cord. I heard a further improvement when I went from the Signal Cable cord to the PS Audio Statement cord. However, I perceived (heard) no difference between the two PS Audio cords in that particular application.

    3. When I was evaluating power conditioners for my home theater subwoofer, a PS Audio Power Plant Premier AC regenerator provided a small improvement in sound quality, but nowhere near enough of an improvement to justify its $2,200 cost in that application. Strangely enough, a $250 PS Audio Soloist SE passive in-wall power conditioner made a surprisingly significant improvement in the subwoofer's performance.

    Most of the members of this forum appear to be performance oriented and thus, even incremental performance gains can translate to a substantial increase in listening pleasure.

    Rather than continuing to pepper (spray) the forum with your "enlightened" insights on the folly of investing in higher performance cables, you might consider investing your time in a forum where more kindred spirits dwell. The Audioholics forum comes to mind.

    Good luck.

    I've been wondering about the AQ cables with DBS for a while now. I'm gonna have to give them a try eventually.

    I see this is an older thread...are you still using these cables, or have you moved on to something else?

    PS: Of course you need the system to make you hear the difference that's crucial.

    I said this in 2007 and still stand by it today. Audioquest cables IMO are the very best cables on earth. At all levels dollar to dollar I find them to shine better then all others in all areas. Some cables do this and that as good but overall nothing IMO is better.

    For custom Install this still stands true. They offer such a beautiful line of custom wires. Wiring racks is such a pleasure with Audioquest. They really understand custom and I still to this very day have no desire to use anything else. Yes I constantly check out others as it's only nature to keep an open mind and give everything a shot. I wonder over to Kimber and Cardos from time to time and find those companies offer excellent products as well. But in the end I stick with Audioquest for so many really good reasons.

    I have had Speaker wires, Optical cables , HDMI cables Analog cables all with the colored braiding and never had any fraying problems.

    I do however build most of my cables now out of their custom series. I don't use any braiding anymore except on the speaker wires as I also have sub cables running to the Mythos ST's. It just keeps things clean.
