Accuphase E-480

Hello, I’m considering the Accuphase E-480 replacing my Simaudio 760 amp and Simaudio 390.

I’m looking for some advice on this because I have been on this audio journey and want to achieve a discernible difference in quality without breaking the bank and then, stop.

Speakers are Sonus Faber Electa Amator iii.

Thanks in advance for your thoughts.
