Ditto what the Moderator and Wayne said. The tweeter will not sound harsh or bright with any of the combo's you mentioned. I'm a huge fan of Emotive, and if you do not like an Emotive product you can return it for a full refund within thirty days.

wow, I have almost exactly the same room set up and listening preferences you do. Very interested in what you choose.

I have a Naim Superuniti and love it - its an all in one with a great DAC. I connect the MacMini with an Audiophilleo 1.

Happy to provide more details if you are interested, and if in the boston area come visit for a listen!
