Audioman, I too have heard that the Core units are good.
We just got back with Isotek for their reasonably priced products which were amazing, until Running Springs came along, but now Running Springs is gone, and Isotek overhaulled all their units.
Want to hear a secret we just got an Istotek Syncro and it was amazing how much more snap and focus we got out of the demo systeem.
We just added one Syncro to the incomming power of the Audio Magic.
I don't know if these would work with a Torus so stay tuned.
