O do Mike era todo cromo, o meu é de cartão muito fininho, e o som fica bem melhor, as notas parece que sem são inerrompidas, com o som parece que tem mais informação, mais "analógico"...

De facto há preços que acho absolutamente disparatados em certos artigos, para mais quando começamos a comparar artigos diferentesMalick wrote:cochinada wrote: Só para teres uma ideia, o interconnect Silver Reference II que tenho entre o AVR e o eAR custa cá para cima de €900.
Também não colocava um disco estabilizador ou lá o que isso é dentro de um leitor.
Pois se, de acordo com o RED BOOK a espessura máxima de um CD já está definida e por exemplo os fabricantes fazem questão de escrever na garantia que não se responsabilizam por danos que possam surgir com o uso de Dual Disks, o aumento de espessura com essa coisa ainda será mais notório!

Jovem, já comparaste a espessura de um Dual Disc com um CD normal? Também é muito pouca coisa...
Dito e feito:
"DualDiscs appear to be based on double-sided DVD technology such as DVD-10, DVD-14 and DVD-18 except that DualDisc technology replaces one of the DVD sides with a CD. The discs are made by fusing together a standard 0.6 mm-thick DVD layer (4.7-gigabyte storage capacity) to a 0.9 mm-thick CD layer (60-minute or 525-megabyte storage capacity), resulting in a 1.5 mm-thick double-sided hybrid disc that contains CD content on one side and DVD content on the other.
The challenge for the designers of DualDisc was to produce a dual-sided disc which was not too thick to play reliably in slot-loading drives, while the CD side was not too thin to be tracked easily by the laser. DVD Plus, though conceptually similar, uses a thicker CD layer and thus is more likely to get stuck in a slot-loading player (although this appears to be almost unknown); DualDisc takes the other course by thinning the CD layer.
Because the 0.9 mm thickness of the DualDisc CD layer does not conform to Red Book CD Specifications, which call for a layer no less than 1.1 mm thick, some CD players may not be able to play the CD side of a DualDisc due to a phenomenon called spherical aberration. As a result, the laser reading the CD side might get a "blurry" picture of the data on the disc; the equivalent of a human reading a book with glasses of the wrong strength. Engineers have tried to get around this by making the pits in the CD layer larger than on a conventional CD. This makes the CD side easier for the laser to read; equivalent to the book using bigger print to make it easier to see, even if the person's glasses are of the wrong strength. The downside to this, however, is that the playing time for the CD layer of some early DualDiscs decreased, from the standard 74 minutes of a conventional CD, to around 60 minutes, although this early limitation now appears to have been overcome.
A better solution to the problem would be to use a different material for the disc as a whole (bonding two dissimilar materials together is problematic, as early hybrid SACD manufacturers found), ie other than the polycarbonate used for regular CDs. This material would need a lower refractive index so that the disc would appear thicker to the laser. The range of suitable materials includes Zeonor, a polymer often used in hybrid SACDs for similar reasons (although the hybrid SACD is actually a dual-layer, rather than a dual-sided product). This option has not apparently been tried by manufacturers, for two reasons: one, substances like Zeonor are a little more expensive and the production costs of DualDiscs are still higher than the record companies would like; and two, the rate of returns of DualDiscs has been extremely small, and the majority of record companies and pressing plants do not, as a result, regard there as being a problem to be overcome.
Because the DualDisc CD layer does not conform to Red Book specifications, Philips and Sony have refused to allow DualDisc titles to carry the CD logo and most DualDiscs contain one of two warnings:
* "This disc is intended to play on standard DVD and CD players.
May not play on certain car, slot load players and mega-disc changers."
* "The audio side of this disc does not conform to CD specifications and therefore not all DVD and CD players will play the audio side of this disc."
The DVD side of a DualDisc completely conforms to the specifications set forth by the DVD Forum and DualDiscs have been cleared to use the DVD logo."

Não devia ser assim:
Super Audio CDs
Super Audio CD (SACD) is an extension of the CD format. A SACD disc is identical to a CD in size and thickness, but it can store more information.
The SACD disc contains two layers. One layer plays on a regular CD player and one layer plays on a SACD player.
All SACD discs contain at least two separate versions of the same musical program. Many discs also contain a third version – multichannel surround sound.
• CD standard stereo – can be played on any CD player
• SACD stereo – enhanced stereo program – can be heard on a SACD player
• SACD multichannel surround sound – can be heard on a multichannel SACD player with multichannel amplifiers and speakers
For SACD discs with the same songs on all layers, the only notation in the record that this is a SACD will be in the notes. Currently there are no special 007 values for SACD.
The notes should be taken directly from the disc surface or the container.
Some examples:
500; ;a “Hybrid multichannel super audio CD. Plays on all SACD and CD players.”
500; ;a “CD Audio, SACD Stereo, SACD Surround Sound.”
500; ;a “This disc is designed for use in both CD-compatible and super audio CD players.”
