Avalon Mixing monitor plus sub or Avalon Eidolon ?

Which would be the better choice?
At this moment , I am listening to a pair of Audio Physic Step SLE with the Finite Elemente Pro stands, a brilliant litle combination.
But they are already 10 years old, how would they compare to the mixing monitor or other high end monitors?
Hi Buff,

did you hear both set ups?
