@mofojo, described in their own words.
Built around the class-leading CD-Pro 8 mechanism from the optical division of StreamUnlimited, and developed in collaboration with Pro-Ject Audio Systems, the CD Box RS 2 T’s drive alone features a high-quality aluminium chassis, carbon fibre cover and a carbon fibre turntable. The mechanism is then equipped with a SANYO HD850 OPU and internally coupled to a CD-84 servo board for maximum information retrieval and transmission. Vibration dampers are mounted on the very rigid carbon fibre chassis, and then the whole surrounding chassis is firmly connected to the body of the CD Box RS2 T for absolute rigidity and minimal vibrations. For reduced resonance, the CD Box RS2 T features a gravity design with a central mass point.
The drive chassis is milled from a solid block of aluminium and engineered to hold firm in any environment. Each turntable is also lathed from steel and chrome plated. This is critical for transportation and ensures it will last a lifetime. The suspension system consists of a rigid carbon fibre plate, carbon fibre tubes, springs, silicon dampers and screws. The suspension, cover and turntable platter is made of pure carbon fibre. Everything that’s gone into engineering this drive has been done to achieve absolute technical and mechanical perfection.
