I have the Rega P1 Plus, which is the P1 with a built in preamp, since I didn’t have a receiver when I bought it. I know it’s Rega’s entry level model, but beyond more expensive materials, I don’t really know what more you’d get by spending more if I’m being honest. Build quality’s good, the tone arm is good, and the motor is silent. Annoyances are the piano black finish is impossible to keep clean, but they’ve changed that to matt recently, and having to take the platter off the move the belt if you want to change the RPM, which I very rarely need to. It’s not really upgradeable either, but again I’m not sure what getting into the constant cycle of upgrades would really get you other than worrying that it’s not good enough. I’d still like a P10 though despite doubting I could hear any difference with it.
