I don't plan to upgrade to the Eclipse version or Callisto. I can
barely tell any difference between my Odyssey Candela ($1500) and my
Aesthetix Calypso Signature.

Running dual sub outs at line level plus low input impedance amp
will prove fruitless for you and is suicide for any fine tube pre amp,
Try going out with subs at speaker level and find an pre owned Atlas.
