This is the third in a series of reviews of HDMI cables. This cable differs fromthe Cardas and Audioquest in that its conductors are copper, without silver plating. In addition, like the Audioquest, there is an aarow at one end. Jim Wang, president of Harmonic Technology, informed me that directionality is important for lengths greater than 7 meters. Lengths less than 7 meters do not impact the sound regardless of orientation.
Since this is the third review of HDMI cable, I wanted to include an explanation as to the reason(s) for auditioning these cables. Essentially, it is in response to PS Audio’s assertion that its power wave transport and dac is optimized, sonically when using I2S via HDMI. According to Steve Nugent of Empirical Audio, PS Audio uses the HDMI connector for their differential I2S, having nothing to do with the HDMI spec. They are just using the connector. A technician at PS Audio has stated that the quality of the shielding and conductors affects noise, and that two HDMI cables may reveal differences in frequency response, but the latter has not been tested by him. I believe that if there were no difference in the performance of HDMI cables when using their digital hardware, eventually such information would be revealed to the user.
I applied the same break-in procedue as used for the Audioquest and Cardas cables, namely, 1 week (about 42 hours) from cable box to TV, followed by 24 hours of a signal between transport and DAC.
Cable Construction
Metal is all copper, 22 strands. Gauge is 24AWG. Geometry satisfies the 1.4 specification. Dielectic is polyethylene. Connectors are gold plated copper. Conductors are soldered to connectors using silver solder. Jim Wang suggested that silver plating exaggerates the impact of the skin effect.

INEX Innovation/Harmonic Technology – The equipment in this roomm consisted of Marten Getz speakers with INEX CD Player ($7500), INEX Pre-A200 preamp ($12,000), INEX mono block amps ($14,000 which includes one pair of 5m interconnects), and all cables by Harmonic Technology. Each time I visit the INEX room at the shows, the sound keeps improving. This year was no exception. I was able to play quite a few tracks on my test CDs in this room. No matter what type or genre of music I played, the sound was very good.

The Harmonic Technology Photon Digital Cable brought such sonic purity to CD playback that it challenged my belief that I needed to upgrade my vintage Muse DAC. Quick on the attack as well as the decay, the space between the notes was silent except for the micro-dynamics of low level room tone when present on the recording. Being used with Class A tube preamp and Monoblocks, the Photon created a large and transparent soundscape with exquisite detail and delineation of position. Perhaps because it breaks the electrical ground between the transport and the DAC, the Photon seems to divide and conquer the noise generated in each of those components. It placed me a little further back from the stage than I’m accustomed, but I could hear more of the music and I was more engaged by it. Though it is completely neutral, it caters particularly well to left brain analytical type listeners. However, if the rest of your system is equally high in quality, the music will likely be enjoyed by all. I don’t normally endorse such expensive cables, but Jim Wang’s Photon Digital, with it’s extraordinary application of opto electrical isolation technology, forces me to break my own rule. Read the full review and if at all possible listen for yourself.

Ever wanted to have an HDMI cable just for your audio needs? Harmonic Technology is proud to introduce the Magic Audio (only) OFC HDMI cable that has been designed for your optimal audio transmissions – such as between PS Audio Wave transports and the PS Audio Wave DAC.
The Magic Audio (ONLY) HDMI Rev. 1.4A is a high speed HDMI cable using only the purest OFC 99.9% pure copper. Although capable of transmitting video images, this HDMI cable is widely known to perform better than many over $500 HDMI cables in the market.
Harmonic Technology’s Brown HDMI (High Definition Multimedia Interface) V 1.4A cable for audio and video connections is suited for High Speed, 3D and Ethernet capabilities. The silver-clad copper HDMI cable runs at extremely high speed (10.2Gbps) with reduced noice, incorporates bi-directional audio transmission and maintains 100% backwards compatibility. The HEAC HDMI has doubled the bandwidth and the resolution from previous HDMI cables.
Features include:
| Harmonic Technology Digital Copper III (75-ohm) Harmonic Technology’s Digital Copper III, terminated in either single-ended RCA or BNC, is a 75-ohm coaxial digital cable manufactured with our proprietary Single Crystal (OCC) copper conductor. The Digital Copper digital cable allows for the highest level of signal purity in a coaxial design – especially in the midrange and treble frequencies. Harmonic richness is greatly increased due to the elimination of crystal boundaries and impurities that can disrupt the integrity of the complex harmonic digital waveform. Using the world’s best connectors and insulation materials, the Digital Copper III is one of the most accurate and pleasing digital cables on the market.
Harmonic Technology’s Digital Copper III greatly reduces grain and fuzz, preserving the harmonic richness of the original recording. A velvety-black background is also highlighted, such that small details appear to be holographically suspended in the soundstage. Since copper has a slightly “rich" sound, with added bass and slightly less treble detail than silver, this copper digital cable will be a great match for systems that need more “sweetness" in the highs. Treble detail is quite smooth and yet very apparent, the best of both worlds. Harmonic Technology’s Digital Copper III is truly a reference product which will transform the sound of your system. |

| Harmonic Technology Digital Silver III (75-ohm) Harmonic Technology’s Digital Sliver III, terminated in either single-ended RCA or BNC, is a 75-Ohm coaxial digital cable manufactured with our proprietary Single Crystal (OCC) silver conductor. The Digital Silver III digital cable allows for the highest level of signal purity in a coaxial design – especially in the midrange and treble frequencies. Harmonic richness is greatly increased due to the elimination of crystal boundaries and impurities that can disrupt the integrity of the complex harmonic digital waveform. Using the world’s best connectors and insulation materials, the Digital Silver III is one of the most accurate and pleasing digital cables on the market. Harmonic Technology’s Digital Silver III is a great choice in almost any high-end system where musicality is a must.
Harmonic Technology’s Digital Silver III ensures a delicate harmonic structure of the complex digital bit-stream is kept utterly intact. You will instantly notice a significant elimination of “grain” and “fuzz” which you previously felt was part of the digital experience. The background becomes “black” and completely silent, with more harmonic richness in the important midrange than you have ever experienced from a digital cable. Imaging becomes three-dimensional and holographic, with more tonal “body” and depth to the sound field. The Digital Silver III is truly an exceptional product. |

Our proprietary Triple-Shield noise reduction design uses three separate shields that operate at differential ground potentials to create the smoothest possible operation. An Oxygen Free copper braided shield, combined with a Cu-Mylar foil & Conductive PVC, ensures the highest signal-to-noise ratio to protect the delicate digital data bit stream. Harmonic Technology’s Digital Copper III digital cable offers the widest bandwidth and frequency range of any digital cable on the market. It allows your digital playback system to sound as good as an original master tape. Dynamic range and background quieting are stunning, finally letting you hear the quality of your transport and DAC for the first time. In addition, the reduction of distortion and glare is amazing, enabling your digital playback system to sound as smooth as the best analog sources. This is a must for professional applications where reference-grade quality is necessary.
