JSA Posted 29 december 2002 Report Share Posted 29 december 2002 Haloa, Is er iemand bekend met eXtended Resolution Compact Discs? Een cdtechniek die misschien wel interessant is voor audiofielen These two functions are taken advantage of during manufacturing. The 20 bit digital signal is then transferred to a PCM-9000 using SDIF-2. The PCM-9000 stores the information on a magneto-optical disk instead of transferring it to the U-matic 1630 format tape. The xrcd process takes advantage of the stability of the magneto-optical disk, as well as its 20 bit capacity, by using it as the audio storage medium for delivery to manufacturing. At the JVC manufacturing plant in Yokohama, the 20 bit PCM-9000 magneto-optical disk is converted to 16 bits using the K2 Super Coding in bit down mode, via a SDIF-2 connection. This stage resolves the high resolution 20 bit signal to 16 bits while retaining the integrity of the low level information, which insures a true 16 bit dynamic range without using noise shaping. The 16 bit signal is then EFM encoded. Another K2 circuit, called the K2 Laser, is used to reshape the EFM signal right before going to the laser of the glass cutter. This last stage is the same circuit used for the K2 Super Coding interface, which eliminates any time based jitter that may be present in the data stream. Throughout this process, the word clock is amplified and distributed to the other stages to keep signal quality at a maximum. Similarly, all equipment is run off regulated AC power feeds to provide a pure base from which to work. All cables and connections between equipment use the SDIF-2 interface for sonic quality and music integrity. Tests determined the SDIF-2 offered a superior transmission of digital audio, far above the AES/EBU standard. A variety of materials, including 24K gold and pure copper were tested. Ultimately aluminum was decided upon after extensive listening tests. The end result of this manufacturing process is the highest quality digital transfer from mastering to compact disc. All of this attention to detail allows the listener to enjoy the music just as the artists, producer, and engineers originally intended it. Every nuance of the performance is duplicated as it was recorded, with higher accuracy in both sound quality and imaging. De keuze is beperkt en de schijfjes zijn duur en ik vraag me dus af of dat het geld waard is. http://205.231.187.178/shopping/ Link to comment Share on other sites More sharing options...
boy2 Posted 30 december 2002 Report Share Posted 30 december 2002 Hoi hoi. Ziet er interessant uit zeg. Ik heb eens wat gegoogled, en kom dan op deze review uit, die zeer positief is. Maar: de review is al vijf jaar oud! En nog altijd ligt de winkel niet vol met XRCD's. Geeft wel te denken natuurlijk... Groetjes, Boy. Link to comment Share on other sites More sharing options...
JSA Posted 30 december 2002 Author Report Share Posted 30 december 2002 Nah, het is niet voor de consument bedoeld. De cd's kun je gewoon bestellen via internet. Maargoed, ik heb ook nog een gold cd von Audio En daar zit ook behoorlijk verschil in. Maar ik weet niet precies wat ze daar mee hebben gedaan.
