Upgrades for Rega P3. Worth it?


Good afternoon, all. Have been considering various upgrades to my Rega P3 and wondering if anyone could share their own experiences with this. In particular, looking for real advice on whether certain upgrades were worthwhile and/or had an observable benefit to sound quality to people who've done them.

I currently have a P3 with an Ortofon 2M Blue cartridge, Clearaudio counterweight, and Pro-ject Tube Box SE II phono stage. Potential upgrades I have considered:
Rega TT PSU power supply,
Groovetracer (or other) subplatter,
Groovetracer (or other) acrylic platter (vs. stock glass),
Phono cartridge replacement

Are any of these really worth doing?

I had a P5, since sold. But I had the Groovetracer reference
subplatter and can echo Jetrexpro..the noise floor dropped.I
didn't care much for the Groovetracer acrylic platter, but
the new delrin platter they make was superb. A marked
improvement over the acrylic and stock glass. If you're a tinkerer may I suggest the dual pulley made by Michael Lim. Of all the upgrades I made it was the most dramatic. Noise floor lowered further, wider sound stage , tighter bass. As for the white belt, I found one on sale and got it to have as a spare. I didn't notice any change whatsoever when I tried it.
Hi Nichomoff,

I think your proposed upgrades are all worthy. I have a P5 and have upgraded it with a Groovetracer subplatter, Delrin platter, counterweight and Rega white belt. It really has transformed the sound of the P5 for the better.

I would start with the subplatter, which would make the most dramatic difference, followed by the speed box.

Look into ditching the Ortofon Blue for a better cartridge. You could go Bronze or Black, or better yet, a Dynavector cart, which matches well with Rega arms.

Good luck!

Rega P3 plus upgrades equal Sota Saphire minus the suspension.

P3- 24 motor upgrade + incognito tone arm wire + Deluxe Groove tracer subplatter + Heavy Weight for tonearm + Iron Audio Acrylic Platter = Sota Saphire, and this is according to someone who owns both tables.

Only you can decide whether or not it's worth it.

Enjoy the music.
Thanks for all the advice! Looks like many folks here are positive on the upgrades. Suppose I shouldn't be too surprised. :)

I also forgot to mention I've been using an old Tri-Pad turntable mat over the glass platter. Have read very good things about this and have been pretty happy with it vs. the stock felt. Anyone else use one of these?

Think over the next year or so I will go for the belt replacement (I think it's time anyway) as well as the Groovetracer subplatter and maybe a Dynavector 10x5 to replace the 2M Blue.
