« surprisingly good sounds »

I trained on Steinway 8 foot grands-but have only been able to use digitals at home and on gigs-and for many years-from the earliest digital pianos to 2023. recently I have been auditioning and comparing (online) almost every digital piano now being made, as well compared to my own workstations-and also virtual pianos such as pianoteq, soundfont pianos. I own an old Korg SP-500-RH II piano action, a Casio PX-560 and 2 88 key Alesis fusions also. also used the Coakley "Perfect Piano for several years. i play classical and jazz and my hearing is pretty good-just had a professional checkup-I've had to rely on "good ears" as a professional musican for a long time. Picked up this module recently out of curiosity-and trying to find the best digital piano, midied it to my fusion TP-40 Fatars and the Korg RH II piano action boards-maybe my hearing is off, but after playing some Chopin, some jazz standards, a little Bach and my own blues and barrel-house-I am baffled that this little module made so many years ago-is standing up very well compared to just about everything else I've listened to. Something must be wrong-but I've listened and played, listened and played-and honestly with my best headsets-i cannot hear much of a remarkable improvement from the latest Kurzweils, Korgs, Yamahas, Nords, Dexibells or anything else. I am stunned by this, my hearing must be betraying me, but every time I've gone to buy a much more expensive new digital piano, and listen carefully to these, I sit down and play this P50m again, and bang, I'm stuck. I can even hear "harmonic resonance" in this module-years before anybody else even mentioned this in their pianos. I must be wrong, I can't hear how this is possible. I even compared this to my 1GB multiple-layered Salamander grand soundfont piano, and the P50 still sounds fantastic. Only the Nord Grand sounds better at least IMO. Please someone tell me I'm wrong about this!
