My Audio and Jazz History "Cheetah" Kenji Kondo As for the RCA cable DBS series Cheetah of audio Qwest, The appearance is beautiful but, This sound quality charmed my heart more than it. American major cable maker ‘Audio Qwest' have improved sound quality by the unique method of new technical DBS (Dairrekutry bias system),that was put on the market last year. It is the method of equipping a cable with a battery and applying direct voltage to an insulator. This time I introduced this inter connect cable RCA "Cheetah" of this DBS loading, so, I want to report the newest information and performance to you, mail magazine readers.

As for the bias voltage of DBS loading, 12V, 24V, and 48V were used at the beginning, Although, in one year, it seems that they have reached the conclusion that voltage was more advantageous to make it high. It was thought that a cable conductor was wrapped in insulation, formed a kind of long capacitor, and caused distortion and loss. However, by adding direct-current bias, Audio Qwest stabilized the insulator, and it succeeded in acquiring the same state which generates a charge ingredient does not exist. I tried to listing for using The SACD DCD-SA1 of DENON and C40 control amplifier of McIntosh. It is transparent, and the clear high-speed response, and also the S/N are good. The high is also solid with delicate. I had a favorable impression in space expression which is transparent. I held Fresher touch. Dumping of low-range and a feeling of energy were also strong, And I thought this is the best for a jazz sound. Cheetah was a model used as the core of an audio Qwest RCA cable that was loading DBS; this is a PSS (high purity single hard silver) conductor, And raised bias voltage 24V from the beginning to 36V this time. A conductor is the beautiful model of perfect game surface silver, and a RCA pin is silver plating.

High resolution and purity, Although this is made from a virgin silver conductor, there is no color in sound quality, Sound is considerably tightened on the natural basis, And I feel a charm the vitality of a jazz sound, and the feeling of sound and power of expression of Vocal. Moreover, I received the decomposition capability was quite high. Low-range increases thickness. It seems that a dynamic feeling and depth are also strengthened. I had the impression which energy increased. I understood that the higher bias voltage has a merit also by the RCA cable which treats a small signal. It is the so-called high speed with contrast. At the super-high, with cymbal, the reality and decomposition of information is reproduced. I have the impression that the tranjent is extremely high and the delicate feeling has preeminently high capability. Although the low-range feeling became tight more, And I heard the low rank model "Panther" of this "Cheetah", When I compares, decomposition capability is more conscientious, there is no peculiarity in sound quality, it coheres, and it is a neutral sound. If I said, it was reference-like and was the almighty RCA cable, and S/N is very high, so, I thought classic lovers also like this. Although the price of "Cheetah" was cheap, I heard this high sound, and was very much satisfied.
