"Rega P8 (I prefer it to the P10)"
why? I am curious
If you heard the P8 and P10 compared in a store demo you would almost certainly prefer the P10. It sounds bigger, more dramatic, more detailed and more dynamic. But if you live with the two for a while, it is another matter.
I owned both the RP8 and the RP10 at the same time, and then the P8 and P10. I ended up selling the RP10 and the P10 for the same reason. The ceramic platter gives the P10 a slightly brittle, slightly bright sound, and notes seem to be fore-shortened. There is a sense in which musical notes do not develop the full range of harmonics, and it sounds oddly artificial and fatiguing. This was with a range of cartridges, using the same phono stage. The P8 sounds smaller, less dramatic, less detailed - but more "normal", IMO more musical and engaging in the long term.
The arm on the P10 is better. I ended up putting a Cardas re-wired RB2000 on my P8, and with an external PSU instead of the Rega wall wart, and this to my ears sounds excellent.
But I should add that the P8 is not my main turntable, which is a Lenco-based PTP Solid 9 with Audio Origami PU7 arm.
