En definitiva discos CD-R virgenes con chapado en oro de 24 Kilates, 99,99% de pureza; y parece ser que la cosa funciona, otro reto para las pruebas ciegas.
Saludos.

Que una copia suene mejor que el original le debería "sonar" raro hasta al más azul de los pitufos.... :mmmh
¿No dicen nada del precio? :sudor

Precio: la tarrina de 25 49,00$, y la tarrina de 50 95,00 $ más gastos de envio.
Que suene mejor que un original lo probaré este fin de semana, con los ojos vendados, no sabré cual me introducen en el CD, lo que si te aseguro que suenan mejor la grabaciones que en por ejemplo un Verbatim, el sonido es más claro, y detallado.

Aqui os pongo el detalle tecnico de estos discos:
----------------------------------------------------------------------------------
TECH SPECIFICATIONS: MFSL 24 KT Gold 650mb ULTRADISC CD-R
Anyone who has ever damaged a CD-R through abrasion or excessive exposure to heat or light knows that CD-Rs are an imperfect technology and it’s all too facile and common to lose priceless data. For ocassions when you can’t afford to endanger your data, Mobile Fidelity Sound Lab is proud to introduce the Ultradisc CD-R. Our 24KT Gold ULTRADISC CD-R is designed for professional, data critical, music and graphic archival applications, and all other data storage where there is no margin for loss or error. These specially-gold-plated ULTRADISC CD-Rs ensure excellent reflectivity, are non corrosive, and have dramatically enhanced resistance to light and heat. Additional features include instantaneous pit burning (burst burning) for superior pit formation and extremely low to no error rate; and an added, patented, scratch resistant, protective surface. Due to these features, little if any error correction is required upon retrieval of information, producing precise reproduction of stored data.Where as the average CD-R has a projected lifespan of only 20 years—if stored in ideal conditions, our accelerated aging tests predict that the 24KT Gold ULTRADISC CD-R will retain its specifications for more than 300 years. Meaning that, now, information can be accurately stored and retrieved longer than ever before.
24 KT Gold Layer
Mobile Fidelity Sound Lab created the world’s first 24 Karat Gold music CD in 1987: The ULTRADISC. Now MFSL has put that expertise in the development of the 24KT Gold ULTRADISC CD-R. The combination of the superior reflectivity and longevity of 99.99% pure 24 Karat Gold, in addition to a specialized, patented bonding agent, ensures that the ULTRADISC CD-R will never oxidize and fail to output information, as many commercially available CD-Rs do. The ULTRADISC CD-R is extremely stable in the real world environment.
Proprietary Photosensitive Dye
Unlike commonly used CD-Rs containing Cyanine (blue/green dye) or Metal Azo (deep blue dye), which lose their characteristics quickly from exposure to light and heat, the 24KT Gold ULTRADISC CD-R utilizes a patented photosensitive dye which ensures accurate burning and stability, plus exceptional longevity and durability. Whereas the two other types of dye are formed with linear molecular structures, which break down easily when exposed to the elements, the unique photosensitive dye utilized in the ULTRADISC CD-R has an annular structure which forms a strong and extremely stable chemical bond. On top of this, MFSL has added a patented, reinforcing coating for extra protection from scratching.
Extremely Accurate and Precise Burning
Mobile Fidelity Sound Lab has chosen to offer only slower speed (1-12X) CD-Rs. Although the current trend is “faster is better,” MFSL engineers strongly disagree and urge audio professionals, archivists, audiophiles, and discriminating collectors alike to burn their data in real time, better known as 1X. Through a careful battery of tests conducted at Mobile Fidelity Sound Lab, we have observed that real-time burning has always yielded superior results. Higher burning rates cause errors and do not allow for proper pit formation. Furthermore, higher speeds cause vibration in the drive when burning the disc, thereby increasing jitter. In order to attain even higher burning accuracy and overall quality, a specially formulated dye was created for these slow-burn, precision ULTRADISC CD-Rs.
Accurate and Precise Information Retrieval
The ULTRADISC CD-R’s specialized dye reacts more quickly to the writing laser than do other dyes. It reacts in a "burst" mode instead of the sluggish "melt" mode. Due to this instantaneous reaction, precise pit edges are formed. This is crucial for the laser pickup to accurately interpret the information, and thereby reducing or eliminating the use of interpolation/error correction circuitry. Additionally, a specially formulated, black ink is used to coat one side of the disc in order to reduce stray reflections which could alter readings.
Ultra Quality Control - 4 Levels of QC
Utilizing the highest quality control standards in the industry, all the manufacturing and packaging of the ULTRADISC CD-R is done in state-of-the-art cleanroom conditions. Mobile Fidelity Sound Lab has rejected random sampling techniques, which are simply not stringent enough for critical data storage applications. Instead, MFSL utilizes an unprecedented 4-level quality control process. First, a sample out of every 3,000 discs is tested, critically examined and evaluated for over 2 hours until given the approval for MFSL specifications. Second, every single ULTRADISC CD-R is tested as it comes off the replication line. High tech, extremely sophisticated computer analysis is used to test jitter, thickness tolerances, gold uniformity and disc eccentricity. Third, an inspector (wearing medical gloves) picks up and visually examines the ULTRADISC CD-Rs for pinholes, gold consistency, oyster shelling, or any other anomalies. Fourth, another inspector repeats this very time-consuming, manual/visual examination just before the specialized, stray-reflection-reducing black coating is applied. ULTRADISC CD-Rs have to pass all levels of QC before they can be shipped. If a disc does not pass Mobile Fidelity Sound Lab’s elevated specifications, it will not be accepted as an ULTRADISC CD-R. This is MFSL’s guarantee to the user that every ULTRADISC CD-R is the finest engineered recordable CD media available in the world.
Limited Lifetime Guarantee
After creating a CD-R that would last a lifetime, MFSL backed it up with a limited lifetime money back guarantee.

Yo pago los soportes.
Me llevo un par de Verbatim o mejor aún "nisu" de la gasolinera de la esquina y la misma música grabada en esos cojo-discos chapados en oro y los usamos para todas las pruebas ciegas en Molingordo. Le ponemos a los equipos caros el CD de oro (ya llevan el cojo cable) y al discman de turno del cable sulfateitor le endiñamos el CutreCD. Son cuatro días de pruebas y un par de decenas de voluntarios.
A la vuelta publicamos los resultados.
Por cierto: supongo que ya con este soporte la mejora absoluta será congelarlo, pintarle el borde de verde y pasarle al equipo antes el superdisco ese de Densen que limpia "los cables".
Re: The Mobile Fidelity Ultradisc CD-R rated #1!
Siempre me ha intrigado una cosa del disco ese limpiacables y limpiachips.. la mierda que se lleva.. donde la deja?
Salu2!
Re: The Mobile Fidelity Ultradisc CD-R rated #1!
Yo he tenido alguna "sorpresa",pero siempre desagradable con alguna copia.Pocas,pero realmente se notaba a la legua,que la copia era inferior al original.y LO REPITO.....SÓLO ALGUNA.
Me acuerdo fundamentalmente del disco de Louis Amstrong y ella fitzerald....Realmente sorprendente. Estábamos 3-4 personas en la sala y nos miramos...esto no suena igual.
Igual fue un problema de ordenador,pero no se escuchaba ningún click..Era sobre todo falta de espacialidad,profundidad y escena sonora.
Ahora bien,no creo que ningún disco mejore un copia,pues no le veo el sentido técnico al asunto.
Lo que si creo es que se conservará mejor el disco y siempre que se pueda,hay que comprar la mejor calidad posible.
Y lo que creo que las mejores copias,por mucho que se diga,son las que se hacen con grabadora doméstica y a 1x.....

la gente con tal de vender...
cómo cojones se va a oír una copia mejor que el original...
si quieren vender que mientan diciendo que va a durar un millón de años más que el original...
que puedes lijarlo con piedar pómez...
que puedes usarlo para cortar cristles... yo qué sé...
pero que suena mejor que el original... andayá

Repito que no sé si suena mejor o peor que el original, lo probaré este fin de semana en prueba ciega e informaré de los resultados; pero resulta curioso que eso lo diga la revista que ha realizado el test con otras marcas de Cd'r, y no el propio fabricante, el cual simplemente dice que el oro es el mejor soporte para almacenar información, tanto para la fase de lectura del laser como para la de quemado del laser, y ya lo llevó a cabo con los discos originales de la serie ULTRADISC y ULTRADISC II, muy valorados por los audiofilos de todo el mundo.

Re: The Mobile Fidelity Ultradisc CD-R rated #1!
De donde no hay, no se puede sacar, así que es imposible que suenen mejor que el original.
Eso sí, te puedes hacer un collar con ellos y colgartelos del cuello y orejas. Menudas joyas.
