excellent immediacy, speed & timing (dont recommend naim, very unnatural forced sound)

no2
forward soundstage (begins at the listening position and extends beyond the speakers)

No3.

I have no idea what this means, and I’ve never experienced a soundstage that begins at the listening position — except with headphones. 
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.
