Audio Refinement complete or Nad C370 ?

Would you share with me some experience?

Have anyone tried the NAD c370, compare to the ARC, I have a chance to get both but can afford one right now (I would need only one for my sister actually).
I would not consider either the Audio Refinement Complete (a very bland sounding integrated) or the NAD C370. Which ARC piece are you looking at?
I enjoyed the Audio Refinement Complete (ARC) that graced my system. One of the few amps I regretted selling.
In my opinion, the Complete is the best solid state integrated amp regularly available for less than $500 (used).
Audio Refinement.
