Although I am looking for a CA98, the seller mentioned that he has a used N2 for sale for $5995, not including my trade or delivery fee. He said he sold this to the original owner about 2 years ago, she was a piano teacher. I didn’t negotiate on that yet as I wanted your advice about an N2 vs a new NV5.
I have never tried the NV5 so I don't know how it compares to the N2, but I have tried every other hybrid and high end DP:s, and for me nothing beats the N2. It is something about it that feels natural. Sure, there are other pianos with a more up-to-date sound engine and the N2 lacks features like USB-audio and bluetooth, but a great instrument is more than the sum of it's parts and for me the N2 stands out in that regard. The way the instrument integrates with the player is for me unmatched, and I even think it exceeds the N3(X) from the players perspective. The cabinet is also the slimmest and space-efficient of all hybrids with grand piano action.
With that beeing said, a used instrument always comes down to what condition it's in and I don't know much about second hand prices in the US. I also believe that IF Yamaha launches a N2X (some say they won't) in the near future, the reselling value of N2:s will be very different.
I have a N1 and I'm very happy with it. It shares the action and the sound engine with the N2, but I would love to have the N2:s sound projection and the TRS-function. The one thing I think is a little funky with the sound is how the string resonance behaves if you press the pedal after you have pressed the keys. It makes a slight increase in volume that doesn't feel very authentic. It also lacks Virtual resonance and some pedal/key noises but that doesn't bother me. The sound is nice and it behaves very natural.
Good luck with your decision, you are choosing between some of the finest DP:S there is so you can hardly go wrong.
