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.
