I bought an older-generation Nord Electro 6 (face panel version 2.1). I've had it since yesterday. I reinstalled my presets, which I know very well, along with the sounds I've created myself, and I can definitively confirm that the sound is better than that of the Nord Electro 6 I bought in 2024: warmer, more depth, and therefore more inspiring.
Spitfire's quartet sound is so magnificent on it; it's a joy to play.
