Jazzdude,
I hope that I did not give the impression that the Cortese is bright in anyway because I don't believe that to be the case from what you and others have said about the unit in this forum and elsewhere. So I apologize if there's any misunderstanding.
If my understanding about the Cortese is correct, it has the balance, neutrality, clarity, detail, impact, immediacy, and dynamics of a First Sound Presence preamp. The Cortese, however, offers a touch more lushness and sweetness than the First, which gives the Cortese a life-like sound that is not too ruthless and unforgiving. It puts instruments and voices in the room in an uncanny way, something few components are capable of.
If my view of the unit, of course without hearing it, is somehow way off base, please correct me. After all, those who have purchased the Cortese began where I am now -- poised to take the leap of faith that will lead to sonic bliss.
