Planar 8 & Neo PSU
The Planar 8 is the second Rega turntable constructed using our latest ultra lightweight Tancast 8 polyurethane foam core (a material developed for the aerospace industry). This material is sandwiched between two layers of HPL (high pressure laminate). HPL is exceptionally thin and extremely rigid. This new construction makes the new Planar 8 skeletal plinth 30% lighter than the original RP8 while offering increased rigidity over the previous model.
A super lightweight plinth combined with a phenolic resin double brace mounted specifically where the increased rigidity is required (between the tonearm mounting and the main hub bearing) forms a structurally sound “stressed beam” assembly. This rigid plinth design prevents energy absorption and unwanted resonances which will add unnatural distortions to the music. Equally, heavier mass can transfer more unwanted energy such as motor or bearing noise directly into the rotating record. The use of braces instead of the complete skin allows double thickness phenolic resin in these key areas, while providing further weight reduction to the plinth which directly addresses the issue of mass absorption and unwanted energy transmission.
For the new RB880 we have introduced an improved vertical bearing assembly constructed using an aluminium and stainless-steel, low mass assembly with vastly improved stability and rigidity. This tonearm is using our advanced preloaded zero tolerance bearing assembly adjusted to less than 1000th of a mm, this gives friction free movement and zero levels of unwanted play. This subtle but effective new structure is only visible via small windows at the rear of the new bias housing assembly (see image below). A thinner stainless steel balance weight is used, allowing greater adjustability and compatibility. Finally, the RB880 is terminated with a re-designed, low capacitance phono cable terminated with high quality, locking phono plugs to ensure the best possible connection.
Hub bearing assembly
The Planar 8 uses a new low mass central bearing assembly. A single piece machined aluminum sub-platter and hardened tool steel spindle run inside a custom brass housing which is cleverly mounted within the chassis. This new mounting is designed to eradicate unwanted potential energy being transferred or stored in the plinth.
Super flywheel effect triple layer glass platter
The Planar 8 uses a three piece laminated glass platter which is the result of collaboration with a British glass engineering company. This brand new platter is constructed from two different high quality Pilkington glasses. As a general rule the only part of a turntable that requires extra mass is the turntable platter in order to achieve constant rotational speed. However, a heavier platter creates more problems for the main bearing design so again an ideal compromise creates the best solution. Practically this means keeping as much of the mass to the outside rim of the glass platter to create more flywheel effect but keeping the inside of the platter as light as possible without sacrificing stiffness.
