I would look at the Musical Fidelity M6si. Doesn't quite double into 4 ohms but it is comfortable driving speakers with lower impedance.
Lively sound that will be forward without being bright. It is a dual mono design though it doesn't have two power supplies. Made in Taiwan which is why it is relatively inexpensive. In that price range it would be my first choice.
A buddy of mine has the Krell and is pretty happy with it. It replaced a Nord. He loves it and it should deliver on what you are looking for.
I haven't heard the other three and have no POV.
I am an MF dealer. PM me if you are interested.
