In addition to my P10, I also have a much more expensive TT, a Linn LP12 upgraded in December 2022 to the latest TOTL LP12 with Radikal 2 power supply and the latest DC motor, Karousel bearing, Ekos SE arm, and Keel subchassis. I think the P10 is the way to go in the Rega line up. The Rega engineers made significant improvements to the P10 over the P8. Also I would get the Apheta 3 MC cartridge over the Exact 2. The P10 is good enough to be an end game turntable for most audiophiles in my opinion.
Here’s an interesting video comparing the P8 and P10 and why this speaker designer/engineer chose the P10 over the P8 to demo his speakers to potential customers wanting to hear his speakers.
