Integrated amp suggestions.

In that price range I'd also look at the Vinni Rossi L2ise integrated, give you a 300B tube based preamp and excellent ss amp section. Just got mine and loving it. The Agostino stuff is excellent when I have heard it at shows, but the Rossi has heart and soul, slam, and detail without any edginess

you are on the right track.
D'Agostino progression.good performance and has a brand cache as well compared to all other brands/models mentioned

My speakers are Sonus Faber Nova 5

Great speaker, have been said to be a hard load a bit like the Amati's which can dive down to nearly 2ohm in the low bass.
For those you want the very best integrated, and to me that will be the Gryphon Diablo 300, it will get the very best out of them. Or the Diablo 120 if you can afford the 300.

I Would listen to Audionet Humboldt

Vitus are a Danish high-end company who make three fabulous integrated amps. I have demoed all three and own two of them and all sound wonderful. Their latest, the SIA-030, has received numerous awards in Asia and Europe recently. Class A to 30W and AB to 200W, it is an extraordinary amp. The Vitus ’sound’ is  neutral although with a  slightly warm, analogue sound. Not the velvety smoothness of a Luxman, and more precise than a McIntosh, but not the dry Hi-Fi sound of a D’Agostino. Think a more valve sound In the mids and top end but with rigid tight and deep bass.
I demoed Sonas Faber speakers with the Vitus SIA-025 and the combination was wonderful, especially with Classical music where the instruments were precisely located in 3 dimensional space and the sound was almost ’live’.
