i think the op is knowledgeable enough to parse through the myriad of comments and ’advice’ posted thus far, separate good advice target to his situation and needs, from the garbage
i would only add a few add’l points here for his benefit
1 - don’t underestimate hegel... they know what they are doing, their gear is really excellent
2 - i agree that arcams’ sound has left me cold for a good long while (cool, shrill sound, little heft or body to the music), but i have not tried their more recent stuff (last 3-4 years) - the nice warmth in his s-f speakers are likely compensating for this presently
3 - op’s sonus fabers should scale up decently for a few upgrade moves, the most significant of which is to integrate in a decent sub (or two)... that would be the most transformative equipment improvement imo (assumes his room and setup are decent)
