Which accuphase should I consider?

I want to get a new integrated and decided on accuphase, I don't wanna spend an obscene amount of money so I'm considering vintage. I was wondering if you guys had the choice between vintage accuphase which would you consider? My budget is around 5-6k. My speakers are JBL L100 classics which are 4 ohm. I heard the class A accuphase's sound very nice but am worried about the power. Should I get an A/B accuphase instead? I don't want want one too old so I was considering the e-470, e-480, e-380, e-560, or e-600? Should I try and get the newest model possible for the latest advancement in the  AVAA volume dial? Any help is appreciated thank you
