Leben CS600 or Atmasphere or ARC

Hi everyone, 
I am using a pair of Devore Nine speakers. I am looking for a tube amp for them. 

My shortlist includes:
- Leben CS600  
- Atmasphere (don't know which model)
- Acoustic Research  (don't know which model)
- Almarro A318B ( love this one but couldn't find a good used one)

My budget is around $5000, so probably I will go for used ones. Could you suggest which one is for me? I mainly listen to acoustic music like vocals, jazz, classical. Texture and timing are important for me. 

Thank you for your inputs!
