I had the Exact 2 MM cartridge for a couple of years and really enjoyed it on my Rega 6. If you can afford the extra $500 or so it would take to get into a P6 with Exact, you will go well beyond the Technics in sound.
But as you know, a turntable is only as good as the TT preamp. Hence, you may want to consider going with the P3 Anniversary table with Exact 2 and add a Rega Fono preamp which would be about the same price as a P6 with Exact 2. Guess you need to dial in your price point. I would also encourage you to, at some point, to add the Rega Couple 3 cable as it perfectly matches Rega turntables and cartridges. It sells for $150.
