There are four options when it comes to the Dominant Pro Violin E strings. The descriptions below should help make a decision on which one is best suited to your instrument and playing style:

• DP01 – TIN PLATED: The plain DOMINANT PRO^® E-string DP01 with a core of carbon steel is tin-plated. A protective layer of nickel is placed between the outer coating of tin and the steel core in order to increase the corrosion resistance compared with conventional tin-plated strings. The string has a very good response, barely whistles, and is well-balanced in its brilliance and warmth. It supports the equilibrium with the A-string and promotes its capacity to carry sound. A specially developed wire treatment makes the sound soft enough that it does not have a screeching effect, and brilliant enough that it offers sufficient radiance, projection and resistance to bow pressure. Despite its small diameter, the string sounds broad and brilliant even without applying much pressure.
• DP01AU – GOLD PLATED: This gold-plated E-string generates a very warm, clear sound that simultaneously conveys brilliance. In addition, the string is extremely corrosion-resistant. In contrast to DP01, the sound is as clear as a bell and the individual sound colours can be clearly and individually distinguished. Combined with its great capacity for projection, this allows it to assert itself very well in orchestras or in chamber music as required. If the system as a whole (instrument, rosin, bow hair and bowing) has a tendency to whistle, ^NO.DP01AU may not be the ideal choice. In this case we recommend DP01. As always, when using a fine tuner hook, it is crucial to make sure that it is always “deburred” (= the sharp edges are filed down), otherwise the string at the fine tuner end can break more easily than normal tin-plated strings.
• DP01PT PLATINUM  PLATED: Of all DOMINANT PRO^® E-strings, DP01PT has the greatest projection capacity. It combines the clarity of the gold-plated DP01AU with the response of the tin-plated DP01. Like DP01AU, DP01PT is also extremely corrosion-resistant, but has less of a tendency to whistle and offers more brilliance in comparison. Due to its outstanding projection capability and clarity, it can be unsuitable for sensitive ears. As a result of its larger diameter (0.268 mm as opposed to DP01 and DP01AU with 0.265 mm), DP01PT offers more resistance to bow pressure and is also better suited to a very low string action. When using a fine tuner with DP01PT, make sure that the sharp edges are rounded down.
• DP01SN TIN PLATED:In comparison to the other E-strings, DP01SN has a smaller diameter and is therefore ideally suited to instruments with a normal or high string action. In comparison to the standard DP01, DP01SN is not underlaid with nickel and is therefore somewhat more susceptible to corrosion. Thanks to a thicker layer of tin, however, it sounds warmer than DP01 and much warmer than DP01AU and DP01PT. It also has the lowest string tension of all DOMINANT PRO^® E-strings, which means that almost no strain is exerted on the instruments and they can be greatly opened in terms of sound. This leads to a good bow response and also promotes the instrument’s radiance. Its low string tension means that it has the lowest resistance to bow pressure of all the DOMINANT PRO^® E-strings.
