If you like your Accuphase P-3000, why not use that with a 3 channel amp or even with 3 of the 5 channels of the Anthem amp you now have? All you need do is distribute the main LR outputs from your processor to the Accuphase and the surrounds and center outputs to the Anthem. I'd check with Anthem to assure their amps are stable even without a load, but if necessary they can advise how to load the 2 unused channels. Of course, you could sell the Anthem and buy a 3 channel amp, or you could add rear speakers to use all 5 channels.
