Why Record Player SG-1 Super Groove?

• Has the heart and body of the RG-1, unrivalled in its own right and second only to RG-1
• Plays every note with the intended emotion and maximum dynamics in any home environment
• Provides an upgrade pathway to RG-1 without compromise if required

Vertere SG-1 Super Groove Record Player

Key feature of the Vertere Record Player SG-1 Super Groove is the same structural coherence as you find on the RG-1 Reference Groove. Both record players use the same high-speed synchronous motor and they have the same structural design, incorporating compliance that isolates the record-playing platform from unwanted movements, whether internally or externally induced.

The external motor drive power supply unit ensures constant speed and smooth running of the motor, which in turn is enclosed and articulated in exactly the same way as with the RG-1.

The differences between the SG-1 Super and the RG-1 Reference are in the bearing and platter assembly. The SG-1 platter system makes use of a high-grade one-piece aluminium alloy platter with a 3mm thick bonded acrylic facing to

provide the record interface. The main bearing of the SG-1 utilises a precision ground hardened stainless steel spindle and a super precision tungsten carbide ball.

The SG-1 shares the same plinth structure design and components as used on the RG-1 and provides the optimum platform for the tonearm and cartridge to work on. There is a pathway to upgrade the SG-1 to the RG-1, by simply replacing the main bearing and platter assemblies if and when desired.

The Record Player SG-1 Super Groove will bring any record collection to life and provide many years of musical enjoyment.
