| TechDAS Air Force OneDesign focus included the following criteria:
• Elimination of all unnecessary vibration and resonance • Absolute rotational accuracy and concentricity • Maximum quietness operation, • Immunity from external vibration • Mounting flexibility for all types of tonearm • User friendliness and an elegant beauty • A choice of platter material and type • Silent, ripple free air pumps The turntable chassis is assembled as a three-layer sandwich that consists of: • Base Chassis, made of A5052 pure aluminum • Middle Chassis, which uses an even stronger A7075 high quality aluminum alloy. It is firmly sandwiched between the two outer layers to eliminate resonance • Upper Chassis that is the visible turntable exterior. As the base, it is made of A5052 aluminum with hard anodized top surface. http://highfidelity.pl/@main-456&lang=en O artigo tem uma janela de destaque curiosa: AAA | DAA | DDA - Is that still “analog”?
The turntable makes it possible to assess the quality of recording and pressing with a previously unattainable level of certainty. No "probably", "but" or "it seems" but the biblical "yes yes, no no". I think that it helped me once and for all to sort out valuation, the basis for the description and evaluation when it comes to the source used for vinyl pressing.
As is known, a vinyl record stores analog signal. However, the signal used to master an acetate disc, which is processed to make a stamper for vinyl pressing, can be analog or digital. In the latter case, it needs to be converted to analog before the acetate master is cut on a cutting lathe. Before 1980 all material, except for very few rare cases, was fully analog from beginning to end. The recording process used analog tape recorders, analog mixing consoles and analog mastering equipment. All these records would be designated as AAA in the SPARS Code, implemented in 1984 by the Society of Professional Audio Recording Services (SPARS) for commercial CD releases. Then things started to get weird. Recording studios began to be equipped with digital recorders and the signal would be then converted to analog and mixed in the analog domain. Their SPARS code would be DAA (digital recording, analog mixing and mastering). With the development of digital audio technology, analog mixing consoles were replaced by digital and their SPARS code would be DDA. Today, almost all records are made in this way. Most of them are DDD, including digital mastering for CDs. Another possibility would be ADA where only mixing is done in the digital domain. When it comes to modern vinyl releases, still referred to as analog discs, they are analog by the name only. | |

| ....e mesmo assim, com um som fabuloso. Há coisas do caneco. No AAA alemão foi inclusive feita uma experiência interessante onde mandaram cortar vinil de master digital para ser tudo igual, e foi consensual que em vinil soava bastante melhor. Mas esta conversa já vem de longe. _________________ Digital Audio - Like Reassembling A Cow From Mince If what I'm hearing is colouration, then bring on the whole rainbow...The essential thing is not knowledge, but character.
