Hemoncdoc, I currently have SF Amati Tradition. Great speaker for sure, to my surprise it disappears better than Serafino that I also had in my home for almost a year. And guess what drove Serafino - Gryphon Diablo 300. Yes great integrated, in different league from plinius 9200. I had all pliniuses with exception of latest Ref. A-300. Great amps for a money, but lacking air and refinement in compare with other like latest pass, Sim audio, GAmut monos. I had to sell Gryphon about 8 months ago for financial reasons. Since that I had luxman 509x - good integrated but no match to gryhpon or pass int-250 that I currently have.Pass int-250 is great integrated, but Gryphon was better with better micro details, dynamics and articulation, pass has bigger soundstage and midrange is more bloomy.
Keep in mind that Gryphon Diablo 300 is a little on dark side ( like very good dark chocolate) not warm so, but a little dark, so even it will greatly drive Sonus Faber but,I personally think that the even greater match for Amati will be high current /high power, low noise fast and refined amplification like Dagostino progression, or Sim audio 870A, or class A/B Rowland (may be 625 S2) or T+A (may be). I am not mentioning ultra high end brands or tubes since I don't have any expose with them. Couple dealers I know swear by T+A 31000HV integrated and I considering it strongly, but I will not proceed (at this level is a requirement) without home demo that so far I can't arrange. So for now I'm staying with pass.
