Just make sure the outputs are "pre" outs and not "tape" outs. Pre outs are variable with the volume control while the tape outputs are line outs set at full volume.
I'm doing the same thing now with a Cairn integrated amp. It has two sets of "pre outs." I hook them up to a pair of Dared VP-20 tube mono amps. I switch the speaker wires back and forth between the Cairn speaker outs and the Dared speaker outs depending on which amp I want to use.
I did own an Audio Refinement Complete a few years ago. I really liked that amp.
