Re-create the live music experience with Record Player RG-1 Reference Groove, Vertere’s finest model and first choice among the world’s high-end turntables.
Offering peerless performance through uncompromising engineering, Vertere’s Record Player RG-1 Reference Groove incorporates innumerable carefully-considered design choices that make it supreme among turntables. The RG-1 includes a super precision main bearing and a two-piece non-resonant platter assembly to provide the most silent platform for the arm and the cartridge. The result is the ‘darkest’ background achievable from vinyl, against which every note played and every word sung comes to life.
The main bearing assembly comprises an aerospace-grade phosphor bronze housing, a super-precision tungsten carbide spindle and silicon nitride ball. The housing is machined and finished to the tightest of tolerances, with the bearing spindle sized to ensure the minimum gap possible between the spindle and the housing. The only contact is between the spindle and the precision ball supporting it at the bottom. The design of the bearing assembly ensures that the ball is housed absolutely central to the spindle. The main bearing is lubricated using Vertere’s proprietary bearing oil, L-1G, which ensures almost perfectly silent running. This lubricating oil is formulated with anti-friction, anti-foaming, water repellent and cooling agents for longevity and best performance. The unique design features of the main bearing, combined with the highest level of precision and attention to detail is mirrored in every other aspect of Vertere’s Record Player RG-1 Reference Groove.
On the main structure of the record player, the drive engine is a Swiss made synchronous motor. Vertere’s unique self-synchronising system for the motor keeps belt tension constant and also keeps any residual noise away from the platter. An external dedicated motor drive power supply unit, precisely tuned to each individual motor, ensures optimum power to the motor while keeping motor noise to a minimum.
Highest-quality cast acrylic has been chosen as the best material for the plinths of the record player, due to its consistent rigidity and naturally non-resonant properties. The plinths are CNC machined from different thicknesses of cast acrylic to their specific designed shapes and are critically isolated from each other. Isolation is provided by several unique suspension components, where every layer is designed to eliminate certain unwanted movements and vibrations – internal or external. The intricate design of the isolation components combined with the stable acrylic plinth structure provides the best possible platform for the tonearm, cartridge and the platter assembly. The result is an unparalleled and an unforgettable musical experience, every time you play a record on the RG-1.
