Integrated for Sonus Faber Guarmeri Memento??

Amp: none
Cd: none
Speaker: sonus faber guarmeri memento
Try to listen to EAR899 70wpc integrated amp. I've listened to it with EAR890(power amp version of 899) and impressed with the overall tonal balance & dynamics of the memento
I've read in several forums that McIntosh is a synergistic match with Sonus Faber. I just rec'd the all tubed McIntosh MA2275 to which I've added upgraded tubes and it sounds stellar! Not sure if 75 WPC is optimal for the memento's 4 ohm min. impedance, but have heard of others using this combo on Audiokarma's McIntosh forum.
I am currently driving my GM's with an Accuphase P-3000, which is 75 wpc into 8 ohms and doubles that output into 4 ohms. The results are excellent. Others have stated on this and other forums that the GM's will sound better with higher powered amps. I cannot confirm or refute that, but in my experience and in my listening room, which is 13' x 19' with an 8' ceiling, the 75 wpc from my P-3000 is everything I need.
Many thanks! Will go to look at all these amps asap
Luxman L-507U.
200 wpc in to 4 ohms.
About McIntosh MA 6600.
I sold my Luxman L-507U in Audiogon.The person who purchased my Luxman was running a McIntosh MA 6600.She told me Luxman L-507U SMOKED the McIntosh MA 6600.

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?
