@emybaneesim:
A thousand thanks.
You're right, my "problem" is that the R3's withdrawal deadline is in a week and I can't compare them directly with the R3 Metal.
The suggested option of returning the R3s and waiting for the Meta to come out so you can buy it at the shop is very good.
Consider that I really like the sound of the R3s, I'm not a "Fan" of the latest model released unless it has a crazy performance.
I can equalize the R3s I have a Nad C 399 and I can use dirac (I'm buying the module) this is a very interesting option.
I also agree that in a few days the price of the R3s will drop again (at least in Italy) I asked the dealer for an additional discount on the ones I just bought (among which they arrived open) if it takes away at least another 100-150 euros I think I'll keep them and if necessary I'll make some corrections with Dirac.
If he doesn't accept the discount, I'll wait for the price to drop and in the meantime we'll have more precise news for the meta series that will help us better understand the differences between the two.
Thank you very much you have been very kind.
Have a good day.
