IMO. I wrote about the characteristics of the shunyata in review here on Audiogone. helix version I had last summer. I have no idea where you wish to place the ICs.
having heard the majority of what components you list recently aside from the amp, (I heard the MXR? 400 MONOS), on sophias all too briefly. I would want a Nirvana SX in there somewhere or a Synergistic.
with the bass the Ayre provides that Altair might do well as the main IC. or as source, but I would not think as both. Depends on waht you are shooting for.
have you asked Shunyata or Nordost?
