Tango spinner or groovetracer subplatter for rega p25

I have the groovetracer, provided more focus, I am happy with the purchase.

Highly recommend the Groovetracer reference subplatter & Groovetracer delrin platter which I have on my P25. Also use the Michell record clamp (non-Rega version with the new subplatter) to gently snug the record to the platter. No mat or any change in VTA is needed with the Groovetracer delrin platter.

I have the Groovetracer sub platter and platter on an old P2.
It is very well made.
I use it with no mat on top of the platter at all.
For the price I think it is a very worthwhile upgrade.
