    High Fidelity Cables

    Hi.
    Can anyone share their experiences with these cables? They come in three different series. I would like to hear about their IC, speaker cables etc. Also build quality, what systems they are used in etc.

    And, comparisons with other cable brands if possible. I have read a lot of positive reviews about them

    Thanks

    I went to this dude's exhibit at the lone star audio fest. He had the most elaborate system there. He explained to me that his cables need magnets to "pull" the signal through the cable. Pure weirdness going on there. He was lucky to have Voxativ speakers, so it sounded decent.

    Here's the crux of the patent they licensed:

    The signal voltage for standard inter-component audio signals is typically between 0 V to 2 volts root mean square (V RMS), and generally with negligible or little current. The frequency range is typically 20 Hz to 20,000 Hz, with some systems requiring a frequency range up to 50,000 Hz. The test signal was a 1,000 Hz sine wave generated with a notebook computer using a TrueRTA real time analyzer (RTA) Tone Generator. A first test was run using a 1 kHz sine wave at −10 dB, or about 0.2 volts amplitude. Because a standard signal voltage level is generally about 1 volt, this test was determined to be run at too low a voltage level to provide meaningful results based on the capabilities of the test setup. Accordingly, a second test was run using a 1 kHz sine wave at a more realistic −3 dB, or about 1.0 volt amplitude, which better represents a typical inter-component voltage level. For completeness, however, the results of both tests are provided below.


    ...



    The results were then analyzed for total harmonic distortion (THD), total harmonic distortion+noise (THD+N), Intermodulation Distortion (IMD), and signal-to-noise ratio (SNR), using SpectraPLUS software. The two tables below provide a summary of the results.

    (Linear Phase
    Filter)
    Magnet Connector Cable
    Sine Computer 0.01798% 0.01842% 0.2553% 74.694 dB
    The test results appear to show a slight decrease in performance for the signal cable using the magnet center-pin at the −10 dB signal level. There was a slight increase in both THD and noise, plus a slight decrease in SNR. The differences were between 0.4% and 3% of the total THD/noise, and the SNR decreased by 0.26 dB. One potential hypothesis for this result is that the signal cable with the magnet center-pin may be allowing lower-level noise within the signal-generating computer to be transmitted through to the digital recorder. That is, the threshold for signal transmission for the cable with the magnet connector may be lower than for the cable with the standard non-magnet connector. Again, and regardless of the actual reason, the −10 dB signal level was determined to be too low to provide meaningful results.



    The test results show a significant improvement in performance for the signal cable using the magnet center-pin at the −3 dB signal level. There was a decrease of approximately 20% for the THD/noise, and there was an increase of the SNR of approximately 1.54 dB. Further, the tests showed an absolute THD+noise reduction of approximately 20% when only the analog signal was changed. There generally would have been THD+noise generated by the signal computer and the Tascam US-122L recording device. There also would be expected to be small levels of THD+noise resulting from the adaptors, both from the computer and into the recording device. The THD+noise from these devices would have been consistent from one test to the other. Thus, the reduction in THD+noise of the signal cable by itself would be expected to have been greater than the measured 20%.

    The only thing this says to me is basically a reaffirmation to keep signal cables (especially phono) away from magnetic fields, as they can be affected based on the signal level

    No thank you. I wouldn't buy anything from Rick Schultz the "Oddiophile". The guy went belly up with his first venture Virtual Dynamics and his "Speed of Light" technology. Now he's hawking the "Magnetic Conduction" technology with his new venture, High Fidelity Cables. It's nothing more that pseudo-scientific babble.

    Then there's this masterpiece:

    Cables are very system dependent.

    I tried the CT-1 interconnects and didn't feel they represented any improved over the new Audience Au24 SEs.

    If you're looking for interconnects, another cable you should check out is the new JPS Superconductor Vs.

    Oh yes, cables are indeed very system dependent. I read in another thread about High Fidelity Cables, but that one ended in a long discussion over other cable brands. Not uncommon!

    The press are very positive about HFC cables, without exeption. I would appreciate more user feedback. I also see that there are many HFC up for sale on Agon, they all ( well almost) say that they will upgrade in the HFC line.

    Actually, the principles behind "Magnetic Conduction" are very similar to those used in the Large Hadron Collider.

    And judging people based on the past failures would mean you'd have to discount 99% of humanity from being worthy of investing in. Like Steve Jobs.

    Actually I don't think VD was Rick's first foray. I think he also did Aural Symphonics that many people liked at the time? Rick also imported audio magazines into Canada for while including mine. BTW, Rick's been in the industry for quite a while and IIRC worked at Audible Illusions for a while?
