First, the "preouts" are OUTPUTS not inputs. To use them you would disconnect your speaker cables from this unit and hook them up to whatever amp you want to use. Then run a set of interconnects from the "preouts" to the "inputs" on the amp.
I haven't owned an Audio Refinement unit, but have done this many times with other equipment. Works well, in most cases.
