Opinions on these budget integrateds?

Thanks everyone, lots of food for thought.

This might sound odd, but I have a strong preference for very simple user interfaces (not least because a non-technical spouse uses the system as well).  I like knobs and buttons that only do one thing, and I’m slightly worried about the Kinki’s multi function knobs... is this silly?

If I narrow down to Belles, Unison, or Parasound, would any of these three be a noticeable upgrade from my NAD?  

As far as multi-function knobs, you may never use them as there is the remote.  The only time I might use the knob on the amp is when I first turn on all my equipment.   In today's world you may be hard pressed to find equipment with dedicated knobs for each function. 

Why would you let your spouse touch the system???  No good can come of that.  Plus, you have to deal with her interface and that's about as complicated as it gets.  What goes around...

You mentioned that you’re looking for an analog integrated amp (no DAC) but on your lists above you included the Parasound Halo Integrated and the Parasound Halo has DAC.
I will add the Rega Elicit-R analog integrated amp to your list but have no idea how it will sound on your Allison One speakers as I’ve never heard your speakers before. However I have heard the Rega Elicit-R on couple different speakers before and it was very musical especially considering its modest asking price of $3k brand new. I’m aware that your budget is only $2k but the Rega Elicit-R can be had around $2k used if you can find one in an after market like here on Audiogon.

I had a Parasound Hint paired with magnepan 1.7 and the sound was magical. You get everything you need even mm and mc phono pre built in with lots of power.
