Integrated for Sonus Faber Guarmeri Memento??

I have tried several amps and integrated amps with my Memento, my favorite amps were BAT 150SE and integrated amps were BAT VK-300X SE. Really brings up the strength of GM, enough resolution, transparency, and extension to mate with somewhat romantic sounding GM. I didn't care for Pass INT-30A with GM, MF Tri Vista was not nearly as refined. I had Mc MC-501 before, defintely not my cup of tea.

Reniy, may I ask why u sold the L507? And what your current amp?
