I sell both Pass and Resolution Audio. I firmly believe the Opus is the best direct capable cd player out there, and one of the best overall at anywhere near its price. We have demoed and owned Accuphase, EMC etc etc, and the Opus beats them all to our ears.
With that said, we run the Opus both direct and through a preamp into our Pass gear. Only with higher end preamps do you notice greater dynamics, i.e., X1 and X0.2. I imagins with your rig you will give up some aspects due to the Ref II being a great preamp. But if you want to get rid of gear and clean up your system, the Opus is a great buy! I beleive it is sonically superior to you DAC and transport, so the main question is do you run direct from the opus or go through the REFII, that is your call and budget decision.
Let me know if I can help at all.
