While my 2023 Planar 2 is not vintage, It none the less didn't sound like the $1,000 CAD I paid for it with it's stock Carbon cartridge. Which I kind of expected. So I had their $500 Nd3 mounted, at 1/2 the price of the table seemed high, but I gave it a try. I also added Rega's Fono Mk5 MM Pre-amp.
After about 10 hours I must say, It's a big improvement over the stock Carbon. Now it sounds as good as the price would suggest.
Another option I considered was a Goldring E3.
For those who already have a planer 2, especially the later ones after 2016, I would recommend the Nd3 if you're budget allows.
I thought it was overpriced at first, but after hearing it through my Bryston amp and Reference 3A speakers I'm quite pleased. It seems a lot of good Cartridges are in this price range.
Hopefully you're getting great results too. The new Planar 2 with its stock Nd3 Cartridge is almost on par with the older generation (before 2016) P3's.
