DS Audio Grand Master EX yhdessä Grand Master 3 Equalizer-vahvistimen kanssa on paras saatavilla oleva ratkaisu DS Audiolta ultratason vinyylisoittimesi osaksi ja seuraksi. Omat LED- ja photo-osat molemmille kanaville. Erittäin hiljainen, musiikki virtaa entistä mustemmalta taustalta. Huippukevyt liikkuva massa – vain murto-osa vrt. perinteiseen MM- ja MC-äänirasiaan. Parantaa seurantaa ja vähentää säröä. Rasian runko ultra duralumiinia, neulanvarsi ja neula yhdestä osasta tehty timantti. Micro Ridge-hionta.
Tinkimättömällä pieteetillä toteutettu järeärakenteinen Equalizer-vahvistin tuplamonorakenteella kahdessa kotelossa. Valittava aliäänisuodin off / 30Hz / 50Hz – kuusi vaihtoehtoa. XLR-ulostulot x 3 ja RCA-ulostulot x 3. Sekä äänirasia että EQ japanilaista tinkimätöntä käsityötä.
One-piece diamond cantilever
The Grand Master Extreme employs a 0.22mm square one-piece diamond cantilever, where the diamond cantilever and the needle tip are crafted from a single diamond. Typically, the diamond tip of the cantilever and the needle tip are bonded together using adhesive. However, with the one-piece diamond cantilever, the cantilever and the needle tip are integrated into a single unit, enabling a more direct transmission of information from the needle tip.
Independent LED and photo-detector arrangement for the left and right channels
The new Grand Master EX optical cartridge system has been optimized by implementing an independent LED and photo-detector arrangement for the left and right channels. As a result, the cartridge output voltage has increased from 40mV to 70mV. The Grand Master cartridge offers an improved S/N ratio compared to its stable mates, resulting in an even lower noise floor and far greater musical clarity.
Weight of the shading plate is reduced by more than 50%
The implementation of independent left and right channel LEDs allow for the positioning of the optical system to be optimized as well as necessitating the use of a newly designed shading plate that has been significantly reduced in size compared to our earlier designs. In addition to this reduction in size, the material used to produce the shading plate has been changed from aluminum (as used in the second-generation cartridges) to 99.9% pure beryllium to reduce its mass further.
The power unit and equalizer unit are completely separate units
The DS Audio Grand Master EX system features a separate equalizer and power supply, each in an independent chassis. Using 2.34 million uF and 2.97 million uF electrolytic capacitors within the equalizer and power supply units, respectively, has resulted in a significantly stronger power supply design and improved reproduction of deeper low frequencies. In addition, the Grand Master equalizer incorporates special film capacitors custom-built to DS Audio’s specifications, along with non-induction winding resistors. The design features three transformers, each with a capacity 1½ times greater than that of the DS Master 1, one for the left and one for right channels, with the third handling the power supply to the optical cartridge.
A total of 6 optional low-frequency cut-off points
The Grand Master equalizer features single-ended RCA and balanced XLR outputs. Additionally, you can choose from 6 different low-frequency cut-off points, allowing it to seamlessly integrate with any hi-fi system.
” Despite my adoration of Decca, Soundsmith and Koetsu pick-ups, HFN Feb ’21 saw me write, ‘TheGrand Master is so truly supreme in resolution, transparency,spatial recreation, neutrality and any other parameter I can name that it’s impossible for me to not say what I usually try to avoid:“This may be the best cartridge I’ve ever heard”. This time, I cannot deny: the Grand Master Extreme is even better.”
