There are three different subplatter models offered by Groovetracer. Their features are listed below.
Each Subplatter is actually a three piece precision assembly. The hub is machined from 6061-T6 Aluminum and the bearing axle is constructed from hardened (RC 62) and ground steel. The third component is the record spindle which is machined and polished from Stainless Steel.
Following assembly, each subplatter is inspected for concentricity.
Groovetracer™ takes pride in offering the finest subplatters available to owners of Rega turntables seeking to improve upon the already fine playback performance offered by the Rega turntable.
Reference - Top of the line in terms of performance. The non resonant interface with the platter separates it from the other subplatters in the line. It also incorporates a sapphire thrust plate (integral with the bearing shaft) that rotates on a zirconia (ZrO2) ball. This combination offers a superior low frictional interface that will last many years and produce an almost silent background for the music to emerge.
This jeweled bearing design truly is a reference, and should you decide to purchase one, you can feel confident knowing you have chosen the best subplatter available for your Rega turntable.
Deluxe - Second only to the Reference, this model enhances the already excellent performance of the Standard model by the inclusion of a sapphire thrust plate and zirconia (ZrO2) ball which is also featured in the top of the line Reference model. This combination offers a superior low frictional interface that will last many years and produce an almost silent background for the music to emerge.
There are also three contact surfaces machined into the aluminum hub to promote positive contact with the platter while minimizing vibration transfer.
The end result is a subplatter that outperforms all others with the exception of the Groovetracer™ Reference model.
Standard - Do not be fooled by the "Standard" designation. The only difference between the Standard and Deluxe models is the exclusion of the sapphire thrust plate, however it does come furnished with a zirconia (ZrO2) ball. This model also receives the same high level of tolerance and finish achieved in both the Reference and Deluxe models.
It features the same subplatter to platter interface offered on the Deluxe model. There are three contact surfaces machined into the aluminum hub to promote positive contact with the platter while minimizing vibration transfer. The bottom two images show this model.

-Important
Features-
1) Low coefficient of friction between
the bearing surfaces minimizes vibration for a lower
noise floor.
2) The record spindle is decoupled from the bearing axle to further reduce vibration transfer to the playing surface.
3) 3 point interface between the Subplatter & Platter ensures positive contact and also minimizes vibration transfer .
4) 0.001 ”or better concentricity between the axle and hub offers vast improvement in pitch control.
5) Extended length record spindle permits the use of clamps.
