Menu These buttons will take you to some of our site's most popular pages You can also use the menu at the top of the page, or this search box: Founded by George Cardas in 1987 , Cardas Audio produces high performance audio cables , premium connectors , the world famous Quad Eutectic Solder , and the finest ultra-pure Copper and Silver strand available. George started the company to perfect audio cables using ultra-pure materials, innovative Golden Ratio resonance control techniques , and uniquely insightful solutions to transmission line problems. The legendary connections and craftsmanship at Cardas reflect George's pursuit of perfection. The company began in Southern California. In 1992, Cardas Audio moved to Bandon , a small town on the southern Oregon coast. While George remains our head product designer, the company is now run by Angela, his youngest daughter. Cardas Audio serves musicians, music lovers, recording studios, and the rest of the high-end audio industry. Our cables are found on some of the finest sounding audio systems, and our wire & connectors are used in world class speakers and electronic components. Our copper & silver wire is even used by other cable manufacturers. Cardas Cables are arranged into product lines, each of which contains a variety of cables designed to perform at a similar level. For example, the Parsec product line contains an interconnect, speaker, power, digital, and headphone cable. Of course, you can mix & match, as all of our product lines play well together. For example system can use Parsec speaker cables , Clear Sky interconnects , and Clear Reflection power cables . Cardas cables also work well in systems that include cables from other manufacturers. Click below to explore our cables. And contact Brian in our tech department if you have any questions. Cardas Cables Elements of a Cardas Cable Choosing The Right Cable Deep Dive! Cardas cables feature our own Grade 1, Ultra Pure Copper wire , produced using a proprietary method developed by George Cardas prior to founding Cardas Audio. No other method of producing copper wire results in the purity and uniform grain structure. For this reason, our copper is used by many other manufacturers, and even in laboratories around the world for it superior electrical and thermal conductivity. We also produce high purity silver wire. Although we don't use silver in our cables, it is used by many other cable and electronics manufacturers. Read more about Cardas Copper & Silver here . Cardas Audio uses Golden Ratio scaled, multi-stranded Litz conductors in all of our cables. The Golden Ratio (1:1618) is found in nature, music, and often used in architecture. Some of the best sounding listening rooms employ Golden Ratio dimensions. Physical dimensions that adhere to this ratio are asthetically pleasing. Rooms built to it eliminate resonances that take away from the listening experience. In a cable, Golden Ratio scaling involves placing the smallest wire at the center of the conductor, with each subsequent layer stepping up in size at a ratio of 1:1.618. This micro-resonance control technique is the subject of one of George Cardas' first patents , US Patent 4,628,151. Litz conductors use multiple strands of wire, each enameled to prevent crosstalk between strands. The enamel coating also prevents the copper wire from oxidizing. All of the cables in our Clear product line feature Matched Propagation Conductors , as described in George Cardas's US Patent 7,674,973. Matched Propagation Conductors offer unprecedented neutrality and clarity. Terminating is the technical (and cool) term for putting a connector onto a cable. The Cardas Terminators are the dedicated and talented group of technicians responsible for terminating cables at our factory in Bandon, Oregon. Their quality work ensures that we're able to offer a lifetime warranty on our cables. Working with Litz wire requires special skill and tools. Click here to see our video series, "Soldering With Jesus", featuring head terminator and shop manager Jesus Ornelas. Cardas Connectors are found on our own cables, as well as cables made by other manufacturers, and on some of the finest speakers and electronic components in our industry. Our connectors are machined from copper or brass billet, and plated with silver, and a flash of rhodium. This plating method not only creates beautiful looking parts, but it also ensures excellent conductivity, with no fears of oxidation. Cardas bulk cable & chassis wires are used throughout high-end audio, as well as by DIY cable & component makers. All feature our Grade 1 Ultra Pure Copper , arranged in Golden Ratio scaled , multi-stranded Litz conductors. Cardas connectors & wire are available to DIY enthusiasts through any Cardas dealer . Manufacturers purchasing in quantity can deal directly through Cardas Audio . Read more about Cardas connectors here . Read more about Cardas bulk cable & chassis wire here . Cardas Quad Eutectic Solder is a proprietary blend of copper, silver, tin, and lead. Qu ad Eutectic Solder is used by the Cardas Terminators, and is widely regarded as the finest solder in our industry, and beyond. The four elements in Qua d Eutectic Solder are in specific proportion to melt and solidify at a temperature lower than that of any of the component metals! Thus the resultant joint is contiguous from wire to connector rather than slurry - this provides a perfect and permanent connection that will never breakdown over time. Quad Eutectic outperforms high-silver-content solder in ease of use, reliability of connection, and audio performance. In fact, we developed it when it was apparent that high-silver-content solder was producing less than ideal results.

The Cardas Speaker Placement Guide. Setting up speakers in a golden ratio, golden cuboid, golden trapagon room, etc.. Speaker placement calculators. Speaker Placement Rectangular Room The Cardas Speaker Placement Guide Setting Up Speakers in a Rectangular Room Very precise speaker placement can open up a whole new dimension in listening, so I will outline the system that is becoming the standard of the industry. This standardized listening room is a Golden Cuboid and is the model for the math used in this system. This method will work with any box speaker, in any reasonably sized rectangular room. You may find that you have already positioned your speakers this way by ear. Active nodes are the main concern when placing speakers in a rectangular room. A node, or the frequency where speakers and parallel walls interact, is proportional to the speaker to the wall distance. The three most importance nodes, in order of importance, are proportional to the distance between the speaker and: 1. The side wall nearest the speaker 2. The rear wall 3. The side wall across from the speaker A secondary factor is the speaker-to-speaker time constant. When you use this Golden Ratio method to set your room up, the speakers are placed so the three nodes progress or differ from one another in Golden Ratio. This eliminates any unison or near unison resonance in the nodes. Panel or dipole speakers such as Apogees and Magnepans cancel their side waves, so a formula of .618 x the ceiling height can be used for determining placement from the rear wall. Most box speakers radiate low frequencies in all directions thus a formula that places the speaker to rear wall distance at 1.618 the side wall distance should be used. Speaker placement, simply stated: The distance from the center of the woofer face to the side walls is: Room Width times .276 (RW x .276) The distance from the center of the woofer face to the wall behind the speaker is: Room Width times .447 (RW x .447) This is all you need to know to place speakers in a symmetrical, rectangular room! The Near Field Listening Position In the near field position the speakers and the listener’s head are the points of an equilateral triangle. Near field listening gives the perfect stereo field. It is frequently used in the recording studio to position the microphones and the voice in the mix. The near field listening position is determined by the "center to center" distance of the speakers and the distance to the listener’s head. It does not refer to the room in any way. The importance of symmetrical speaker placement in a small room cannot be over emphasized. Once the speakers are set as close to perfect as possible, you must angle them slightly toward the listening position. This can be done by ear and usually a ¼ to ½ inch tweek will do. Box speakers generally require a bit more toe-in than planear speakers. You will be able to hear a center focused voice clarify when the sweet spot is hit. Near Field Golden Cuboid Listening Room Diagram The Golden Cuboid listening room is 10’ x 16’ x 26’ (Read 10.000 x 16.18033989... x 26.18033989... Its dimensions differ in a Golden Ratio or Fibonacci sequence (5-8-13-21-34...). The three major room nodes progress or differ in Golden Ratio and thus null rather than add or beat. Golden Cuboid Listening Room Relationships Expressed in Golden Ratio The Golden Ratio listening room is a relationship of potential nodes or energy storage units and can be expressed as a ratio or Golden Progression, using the speaker to speaker distance as 1. Golden Ratio Listening Room Relationships Expressed in Fibonacci Progression The Golden Ratio room set-up can be seen as a Fibonacci progression. Fibonacci Horizontal Listening Rooms If you are forced to place your speakers on the long side of a symmetrical, rectangular room, create a Golden rectangle in each rear corner. Your speakers can then be placed anywhere along a line extending from the outside rear corner through the inside front corner (Diagram F). Golden Rectangles, 1.618 from the side walls x 1 from the rear wall, create diagonal lines for speaker placement in a horizontal room. Horizontal Square Listening Rooms If you have the misfortune to have a square listening room, as in the previous setup (Diagram F), create Golden Rectangles in the rear corners of the room. Your speakers can then be placed along lines extending from the outside rear corners through the inside front corners (Diagram G). Square The Golden Trapagon The Golden Cuboid (Diagram H) is the best "rectangular" shape for a listening room. If, however, you have full architectural freedom, a Golden Trapagon (Diagram I) is by far the favored shape. A Golden Trapagon has a Golden rectangle for the front wall behind the speakers, and the room progresses to a larger (by Golden Ratio in area) Golden rectangle back wall behind the listener. For example, if the wall behind the speakers is 10 feet x 16 feet, the room would then be 26 feet long and the wall behind the listener would be 13 feet x 21 feet. Ideally, the rear portion of this room would vent into an attic space filled with fiberglass insulation. The trick to a Golden Trapagon shaped room is it eliminates the problem of parallel walls and the slap and sharp nodes associated with them. The "sound" of this room is a decaying hologram of the original, not a slap. This decay is exponential, or higher, at all frequencies. The relationship between the height and the width of the room, at any point, is Golden Ratio. The cross-section area at the rear of the room is 1.618 times the cross-section of the front. In the example above, the ceiling height would be 12.72 feet. The ratio of front height or width, to rear height or width, is 1.272 to 1. 1.272 is the square root of 1.618 or Golden Ratio. The progression of size at the ends of the room is a area relationship. The sound confronts the entire surface of the end walls at the same time, rather than progressively as with height and width. It is like tuning a guitar to a major chord, the side walls become the strings and the end walls are the bridge and tailpiece. Golden Trapagon Speaker Placement Calculators As with the information above, these calculators will provide ideal speaker locations, but do not take into account factors such as asymmetrical rooms, furniture, window & door location, or spousal approval. Use the information generated by these calculators as general guidance , but realize they may give you suggested speaker locations that simply aren't feasible in your room.

Information about avoiding counterfeit cables, the value of a certificate of authenticity, warranty cards, authentication service. There are many counterfeit cables on the market. This page should help you avoid them. Top Counterfeits Counterfeit Cable Info Certificates of Authenticity Authentication Service We rarely post clips from our local (Bandon, Oregon) public access cable show, as the topics are rarely audio related, but on this episode we had Cardas head terminator Jesus Ornelas join us to talk about counterfeit Cardas cables. Counterfeit Cables We're proud that Cardas cables retain high resale value, even years after their production. But unfortunately, some unscrupulous opportunists prey upon unsuspecting consumers by selling counterfeits of our cables. Some of these fakes are remarkably well done, visually, and even come in authentic looking packaging. Others barely try, slapping "Cardas" on cables that don't look like anything we've ever made. This is a buyer-be-ware situation. Some buyers are able to return their counterfeit products for a refund. But most are left without recourse. Frequently Asked Questions About Counterfeits: How can I identify c ounterfeit s from authentic cables on the second-hand market? Work at Cardas Audio for at least 10 years 😁. Our long-term employees can usually spot a fake about as fast as a mother can recognize her own child. Assuming you don't work here (and statistically, you probably don't), avoid AliExpress . They pretend to have a mechanism for reporting counterfeits, but it is littered with dead links and buttons that can't be clicked. More trustworthy sources of second hand gear are Audiogon in the US and Canuck Audio Mart in Canada. Fakes rarely show up on these sites, and when they do, they're both quick to remove them. There are probably trustworthy audio-focused sites in other countries. If you know of one, send us a link. If it looks good to us, we'll list it here. And of course, consider buying from a Cardas dealer. Many of our dealers take trade-ins, and might have pre-owned cables. Are some cables mo re counterfeited than others? Yes. The two most commonly counterfeited Cardas cables are Hexlink and Clear Light. Hexlink was a flagship cable from many years ago. There were many iterations, all using the word "Hexlink". It is, by far, the most faked cable. So much so that the majority of listings for Cardas Hexlink cables are fraudulent. The counterfeiters have produced more fake Hexlink than we ever made of the real thing. Clear Light is a more recent cable, and for whatever reason, is now quite commonly counterfeited. And whereas Hexlink fakes stand out (to us) like a sore thumb and can almost always be identified from pictures, Clear Light fakes are really well done (on the outside. Inside is garbage wire), including authentic looking packaging and documentation. Be very cautious when considering the purchase of any cable labeled as Hexlink or Clear Light. And be very cautious when the price seems too good to be true. A recent search of eBay for "Hexlink" revealed hundreds of fakes with "Buy It Now" prices of around $50 USD, and one authentic cable with an asking price of $700. You can guess which one is real. What sort of wire is inside counterfeit cables? Bad wire. We've taken apart many counterfeits, and what we find is just hardware-store wire, at best. It doesn't even appear to be up to OFHC or OCC standards, much less Cardas Ultra Pure Grade 1 standards. Why don't you do something to stop the counterfeiters? We have worked lawyers to fight the problem. We've scoured the internet to find & report counterfeits. We've happily checked links submitted by people considering second-hand cables, and told them whether the cables seem authentic or not. And we have this page on our site. There isn't much more we can do. Be cautious when buying second hand cables from private parties, or non-Cardas dealers. Be skeptical when cables are being sold far below market value. Even a long discontinued product such as Hexlink should command $300 to $600 or more for an interconnect or speaker cable. And it won't look shiny & new. It was made at least 20 years ago. It's going to show some wear. If you see a "Hexlink" cable for $30 to $60 and it looks fresh off the production line... it's fake. Shameless plug: Buy a new cable :) We are proud that our cables retain second-hand value, including cables we made decades ago. However, vintage cables deliver vintage performance. If you're looking at Cross or Hexlink on the second-hand market, realize you'll get higher performance from Iridium on the new-market. And you can buy Iridium with confidence that it's genuine. Buying a vintage cable and expecting modern performance would be like buying a 1980's BMW 3-series, expecting 2025 3-series performance. If you want the vintage car experience, get the one from the 80's. If you want modern day performance, you're better off with a new cable from our current product line. We realize that's an obvious statement coming from the manufacturer, and we invite you take it with a grain of salt. Countefeit Certificates / Warranty Cards New Cardas Cables come with a numbered warranty card. Re-terminated cables are issued a new card, which supersedes the cable's original card . The function of this numbered card is to track quality control issues with new or recently serviced cables. If a customer receives a cable that has an issue (which is exceedingly rare), the number on the card helps us track down the production date and batch number. Second hand cable buyers often inflate the significance of these warranty cards. While it is nice to buy a used product that comes with all of the original materials, please know that a numbered piece of paper does not guarantee that the accompanying product is authentic. As with any Certificate Of Authenticity, its only value is to the person to whom it was first issued. If you purchased an historic artifact or a baseball card that came with a COA, you still wouldn't have full confidence in the item until you submitted it to an authority and received your own COA. Our point is to remind second-hand buyers that while receiving a COA with your cable is better than not, it is not a promise of authenticity. We have seen cables offered for sale (and even received them for inspection) that were obvious counterfeits, yet were sold with a numbered certificate. NOTE: The design of the warranty card is updated several times a year, and the latest version(s) will not be depicted here. The image above shows a few previous designs. Please not not over-inflate the value/purpose of the warranty card. It is valuable to the original owner, as in the unlikely event of initial issues with a product, it allows us to trace every step of its production. On the second hand market, it's nice to receive the warranty card as part of a complete package, but the inclusion of a warranty card does not prove authenticity. Many fake cables come with fake cards with numbers copied from real cards. If you have a new Cardas cable, and you are concerned about authenticity, please check our dealer/distributor list to verify that it was purchased through an authorized dealer . Outside of the US, please contact your country's distributor , as Cardas Audio does not have a list of dealers outside of the US. Each Cardas distributor has a list of their own dealers. COA Authentication Service If you have a second hand Cardas cable, you can send it to our facility for inspection. There is a $25 charge, and if your cable passes inspection, you will receive a new warranty certificate along with your returned cable. Please note that cables found to be counterfeit will be indelibly marked or branded as such before being returned. We suggest you only use our authentication service if you are 99% sure that what you have is a genuine Cardas cable, and you just want additional peace of mind. If you are even slightly suspicious that your cable is fake, your best bet is to return it to the seller for a refund. If you'd like to send your cable in for authentication, please obtain a Return Authorization Number by clicking the button below. You are welcome to send us pictures via email of your cable before you send them in. We can't guarantee authenticity from pictures, but we can often identify fakes in this manner, and save you the hassle of sending them in. Return Authorization Form Authentication

Cardas Audio produces copper using a proprietary process that results in copper that exceeds the electrical and thermal conductivity of anything else on the market, including OFHC copper and OCC copper. Cardas copper is used by other manufacturers, and in laboratories worldwide. We also produce ultra pure silver wire. Top Cardas Copper Cardas Copper A Look Below The Surface We eletrically etched three copper strands, and placed them under the microscope (standard OFC copper, Continuous Cast Copper, and our own Grade 1 C opper), to demonstrate that the perfect structure of Cardas copper continues below the surface, which leads to its superior electrical and thermal conductivity. The Story of Cardas Copper, by George Cardas. I was forced into the copper business, when a combination of recycling laws and new "improved" drawing techniques, flooded the market with cheap low grade copper. This began to force traditional plants out of business. I found an "old fashioned" plant that was closing and we began slow drawing and annealing pure copper rod in inert atmospheres. Soon we were supplying most of the specialty drawn high purity metals used in high-end audio. This formula endured for two decades. Recently a series of events lead us to the ultimate knowledge and development of our most amazing metal. Most of our metals are being sold to audio related consumers, however, several non audio customers purchased them for their own unique reasons. My relationship with two of these customers and a boost from Joe Harley (AQ) led to this break through. The first clue came from a customer who we make a custom cable for. He named it Low Thermal because it was used in accurately measuring minute DC variations without temperature induced variation. At the time, we gave little thought to metal, thinking the reason for it's superior performance was low dielectric involvement. In retrospect it is clear that the conductor was a big part of the equation. We had spent considerable time working on eddy currents in the connections, this should have been a clue. The second clue was from a customer that was using miles of fine copper strand to cool micro chips in a detector used in a cyclotron. He didn't even care if it conducted electricity! We shared the most interesting set of information. He had discovered that detectors quite removed from the collider itself were responding at distance to collisions occurring in the device. To reduce the noise in detector chips they were bonding fine copper strands to the chip substrates and immersing the strands in liquid helium to cool them. But commercial copper was loosing its thermo conductivity around 40 degrees kelvin (-387.67° F / -233.15° C). He was interested in our metal for its thermal properties! As it happens, I had just developed a very cool way of looking at strand grain structure under high magnification. I thought I could see his problem in the grain pictures. After viewing them, he agreed and was willing to help me take the next step. I had discovered by ear, that short cuts in the refining and drawing of metals degraded their audio performance. I knew that pure soft metals and meticulous attention to drawing techniques yeilded a quieter strand. For decades we have produced the lion’s share of the copper and silver for high-end audio. I now had the opportunity to better understand the problem. It seemed both our concerns related to grain structure. I had developed methods for viewing grain structure and measuring eddy currents in conductors and now I had a new perspective from a different world and everything was pointing in the same direction. There was a correlation between low temperature thermal conductivity and inter transient noise in room temperature conductors! I was pumped. I asked my customer why he thought the thermo conductivity of some copper was superior to others. He said that thermo conductivity in metals was in free electrons predominantly until about 40degrees Kelvin. At this point the free electron supply dried up and conductivity was phonetic (vibrations directly through the contiguous crystalline structure). This made sense in many ways. What we had discovered in commercial copper was a severe shredding of the crystalline structure. Basically, charges and heat flow are scattered by impurities, imperfections, and inhomogeneous metal structure. The shredding of the crystalline structure was from drawing the strand too fast and the interleaving of impurities (predominantly copper oxide). We saw that casting or extruding pure copper could change that structure. We learned that slowly drawing and annealing very pure copper resulted in less shredding and melded the metal even better. Carrying the process further, we found that using a pure steam or an inert nitrogen atmosphere, help the metal to bond during the processing. It seemed that eliminating oxygen while slow drawing and annealing produced a better structure. Once formed it seemed to self heal as long as there was no oxygen present. I decided to try somthing. We would draw and anneal even slower in a reducing (oxygen scavenging) atmosphere(hydrogen H+) to completely eliminate every trace of oxygen to allow the drawn metal to reform continuously as it was drawn and annealed. The results were beautiful! The new metal was more contiguous in the interior than on the surface. This conductor is the most grain free copper ever produced for audio purposes.
