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.

The following cables can be upgraded to with your trade: Sky X4, Cygnus, Reflection, Clear, and Clear Beyond. Getting Started The trade-in and purchase of your new Cardas Cables will go through a Cardas dealer. To get started either contact your dealer, or click this button to complete the upgrade form: Cardas Upgrade Application Trade-in credit table Restrictions & Fine Details Offer limited to Cardas Cables in our current product line. Legacy cables are not eligible to be traded in, or traded up to. See above for the list of eligible cables. Trade-in credit must be applied to the purchase of a new Cardas cable from an authorized dealer. Trade in value can only be applied to cables of the same type. For example, a pair of interconnects can be traded in on another pair of interconnects. But not a power cable or a speaker cable. A Speaker cable can be traded towards another speaker cable, etc. Traded-in cables must be in reasonably good shape. Even a cable that's been in your system for years should still appear basically brand new. Cables live an easy life. We're not taking cables with inexplicable wear & tear on trade. At least one photo will be required. You can upload a photo using the form above. If that isn't possible, you can email one later in the process. But we do require at least one photo (and we may ask for more) to complete the trade. Traded-in cables must be applied towards the immediate purchase of new Cardas cables. The Cardas orders department must receive a P.O. for the new cables associated with the trade. Trade-ins must be of equal or shorter length than the new cable being purchased. For example, you can trade in a 1 meter cable towards the purchase of a 2 meter. But you can't trade a 2 meter towards the purchase of a 1 meter. RCA interconnects can be traded in for XLR interconnects of a higher-end product. And vice versa. Same with speaker cables with spades vs bananas. Power cables can only be traded in for power cables with the same plug. For example, we're not taking a Euro (Schuko) power cable in on trade for a US cable, nor the other way around.

The artwork of Bob Graham, Cardas Audio's original graphic artist. Bob created the Cardas Nautilus logo, as well as all of our marketing materials from 1987-2012. Bob Graham was Cardas Audio's first graphic designer and marketing director. He created our legendary Nautilus logo, and all of our magazine advertisements from the late 1980's through 2012. Bob and George Cardas worked together long before the founding of the company, with Bob designing the logo and advertisements for Cardas Racing Fuel. Bob and his wife Linda were amongst the members of the Cardas team who made the move from Southern California to Bandon, Oregon in 1992. Bob passed away June 28th, 2023, in Bandon. Prior to founding Cardas Audio, George Cardas was a race car driver and race team leader, and had his own blend of fuel. Bob Graham created this humorous illustration depicting George being placed into a fuel tank. All Cardas conductors employ Golden Ratio scaled stranding. In fact, the Golden Ratio is employed in a number of our products, even our Myrtlewood blocks. Bob created our Nautilus logo (original on the left, redesigned version on the right), which is not only instantly recognizable in our industry, but perfectly embodies this design principal. Most of the artwork adorning the walls of the Cardas shop and office comes from Bob Graham. George Cardas admiring a framed print of one of Bob's Cardas Audio advertisements.

Parsec “My dealer sent me home with a Parsec power cable to try on my integrated amp. I wasn’t sure what to expect, but I was really surprised by how it basically woke my system up. More dynamic, more sparkle on the high end. I called to tell him I wouldn’t be bringing it back, and told him to get a pair of Parsec speaker cables on order for me. Again, huge gains from the speaker cables. My current plan is to get my entire system wired up with Parsec.” -J.

Info For New Owners Register Your Cables Installing Cardas Cables Cable Break-In Installing Cardas Cables Not all of our cables are directional , however the safe bet is to install them as if they are. Always turn off your amplifier when connecting speaker cables. And start by connecting the cables to your speakers, and then to the amplifier. It's never a bad idea to turn everything off when changing cables, including interconnects. But at the very least, turn the volume to zero first. To install correctly, the signal should flow through the cable in the same direction that the text reads on the jacket. This image illustrates the concept: Installation

Many Cardas dealers have a spool of 101 at their shop, and if not, you can order as much or as little as you need. There is no more economical way of putting Cardas in your system than 101 Speaker! Preparing 101 is simple: 1. Cut back a couple inches of the grey outer jacket, and you'll find two 14 AWG conductors, surrounded by white cotton dielectric. 2. Cut away the dielectric, and strip about an inch of the red & black jackets from the conductor. 3. Untwist the copper wires, and you'll find a non-conductive core filament. Snip that away, and re-twist the conductor. 4. At this point, you can use it as a bare-wire cable, and insert the twisted copper into your binding posts. Or solder spades or bananas onto the ends. You can also use crimping spades with 101 Speaker.

Headphone Cables Bring Your Headphones To The Next Level Around the turn of the century, Angela Cardas was an announcer at a radio station in Albany, Oregon. She used Sennheiser HD600 headphones, and due to constant abuse that headphones go through in the broadcasting world, she found herself going through cables several times a year.Finally, she said to her father, George Cardas, "Hey, you make cables. Can't you make a headphone cable for me?" So George went to work developing a headphone cable. What he came up with was not only more durable, but to her delight, it also made the headphones sound even better.That R&D project turned into the first Cardas Headphone cable. And launched what has become an entire product line here at Cardas Audio. Parsec Headphone Clear Reflection Headphone Clear Headphone Clear Beyond Headphone Adapters & Interconnects Where To Buy Parsec Headphone has all the legendary benefits Cardas is known for: richness, warmth, detail, non fatiguing, musical, etc. The cable is very flexible and the rubber jacket slides nicely without snagging your clothing.

The Clear Beyond Headphone Cable project began due to the prodding from a handful of loyal customers who wanted to see us push the envelope, and outdo our vener able Clear Headphone Cable. This was no small task, and took several years. Clear Headphone Cable required the development of the first miniaturized concentricMatched Propagation Conductor, which presented challenges in both production and termination. Once those were conquered, we had a cable that expanded the performance of every headphone on which we tried it. But the idea of taking it to the next step was daunting. We began, naturally, by looking at ways to improve the conductor. Taking cues from Clear Beyond Interconnect, we refined the stranding and braiding, creating a finer arrangement of Grade 1 Ultra Pure Cardas Copper wire. This yielded notable improvements, but we knew we could take it further by doing something we’ve never done before - adding silver. Our all new Hybrid Metallurgy Matched Propagation Conductor features a 30 awg strand of Cardas Grade 1 Silver Wire, in addition to the many improve- ments we’ve made from the starting point of Clear Headphone Cable. Theresults are spectacular. As with Clear Headphone, Clear Beyond Headphone has two separate cables, one for each channel. Braided blue & black thread, and joined together with beautiful hardware to give it “the look” it deserves. Standard Termination: There are too many options available to list them all.
