After owning the P3 for several months, I'm slowly starting to look at some upgrades and needed some advice and information. Setup is the P3 (2016 model I guess they call it) connected to a Moon 110LP v2 to receiver (direct mode). - Subplatter - Read some threads on this, any major different between GrooveTracer and the Tango Spinner? I have read many great reviews on GT so far. - If going the GT route, Standard vs Reference? again big difference? price gap isn't huges, so I guess Reference? - Belt - Is it also suggested to upgrade to the white Rega belt as well? Lastly, as a side note question (hopefully it is not a massive conversation of it's own). Looking at everything now, trying to do a comparison, and I don't think I have enough knowledge to really understand the difference 100%. How does a P3, with NEO PSU, Exact cartridge, Rega white belt and GT sub compare to a P6 w/ Exact and GT sub with the included Neo of course?
