Hello,
If you are happy with the sound then the juice was worth the squeeze. Please stop there improving the Rega P3. If you feel you need more then buy the P6 with the regular MM cart, swap carts with your P3 and sell your P3. So many people have spent a lot of Money turning the P3 into the P6 only coming up short because the plinth is better on the P6. It’s like spending $70,000 on your Honda Civic to turn it into a Porsche. Sell the civic and go buy the Porsche. Once you buy the P6 you will be able to stop especially if you put the MC cart you have on it.
