Termination-SpeakerSide: Product Description CV-4 with NEW Dielectric-Bias System might look like a normal round cable, but inside is a fully optimized combination of extraordinary materials and extremely refined design. Whenever a cable does not have a charge on it, it is re-adapting to an uncharged state; it is becoming new again. By maintaining a 36 volt dielectric-bias, far above the voltage of delicate audio signals, the DBS system provides considerably better transparency and dynamics than is possible even from a cable in continuous use. It takes a couple of weeks for the DBS system to reach maximum performance.

Termination-SpeakerSide: Product Description CV-4 with NEW Dielectric-Bias System might look like a normal round cable, but inside is a fully optimized combination of extraordinary materials and extremely refined design. Whenever a cable does not have a charge on it, it is re-adapting to an uncharged state; it is becoming new again.
By maintaining a 36 volt dielectric-bias, far above the voltage of delicate audio signals, the DBS system provides considerably better transparency and dynamics than is possible even from a cable in continuous use. It takes a couple of weeks for the DBS system to reach maximum performance. Since DBS battery packs are attached when Mont Blanc cables are first terminated, Mont Blanc will be approaching or at peak performance by the time it is installed in your system.
A test button and LED allow for occasional verification of battery performance. Electrical and magnetic interaction between strands in a conventional cable is the single greatest source of distortion, often causing a somewhat harsh, dirty and confused sound.
Whether a conductor is solid or stranded, skin-effect is a prime distortion mechanism in speaker cables. CV-4 very simply keeps this effect out of the audio range by using conductor sizes that are below the threshold for audible distortion.
Even though radially symmetrical conductors solid round or tubular have the fewest discontinuities, any particular size does have a sonic signature. SST is a method for significantly reducing the awareness of these character flaws by using a precise combination of different size conductors. SST has enabled CV-4 to be the biggest possible four conductor cable that avoids audible skin-effect.
When high-purity low-oxide copper is kept as soft, pure and smooth as possible, it becomes a wonderfully low distortion conductor. For fifteen years AudioQuest has pioneered the use of superior metals; yet even we were surprised by the huge leap in performance. PSC clearly outperforms previous AQ metals that cost over ten times as much. All drawn metal exhibits directionality, whether in hardware store wire or in the best AQ cable.
We wish we could design away this awkwardness. Please watch for these markings when installing any audio cables. However, even when those variables are kept in a reasonable balance, the relationship between conductors can be varied in ways that greatly effect the sound.
The spiral construction of CV-4 allows for significantly better dynamic contrast and information intelligibility than if the same conductors were run in parallel.
The specific 4-cross geometry used in CV-4 maximizes this advantage. The harder the better in order to minimize strand movement. Terminations: AudioQuest offers a wide range of high quality connectors that allow CV-4 to be securely attached to any type of equipment. AQ ends are either a dull looking gold or silver because these metals are plated directly over the connector. There is no shiny and harsh sounding nickel layer underneath.
AQ spade lugs are soft because better metal is soft, and facilitates a higher quality connection. AQ spade lugs are available in several sizes. A combination of these major ingredients, and many more subtle details add up to explain how even an affordable cable like CV-4 can sound so good.
AudioQuest CV-4 review
They are therefore implicitly recommended. Where a cable has been found to have specific matching requirements or an identifiable sonic signature, it is noted in the text. Very-low-level detail, however, was lost. Similarly, wrote BD, "While the soundstage as a whole was reasonably deep, the individual images lacked dimensionality.
A bit expensive Still needs improvement One of the vintage names in audio cables, AudioQuest has remained true over the years to certain design principles while still managing to innovate. This is a rather interesting idea, which uses a small battery housed in a plastic moulding which clips to the side of the cable to provide a volt bias to the insulation within the cable, effectively stressing it uni-directionally before any audio signal is applied. Come to that, the claims AudioQuest makes for the existence of distortion in normal cables are not well supported by scientific evidence. Anyway, the star-quad geometry with four mixed-diameter cables and the low-to moderate resistance, will do no harm at all to an audio signal. It seems to have a nice solid bass with plenty of rhythmic impact, but also a pleasingly tuneful quality, and this makes for sound which grabs the attention and holds it well too.
