I’d think PrimaLuna would sound nice with A series, but haven’t heard it to verify.
FWIW, I use Audio Research DSI200 integrated amp with my D7’s.
I think both the A and D series are not too difficult to drive; pretty easy impedance curves as noted; not extremely high sensitivity ratings but decent.
As you probably know, A series doesn’t come with grills, so the drivers are exposed. I find that the A4 looks kind of strange because the mid-bass driver has a somewhat truncated look (don’t have full circle of material surrounding the driver - like sides are shaved off), almost like the cabinet is not quite wide enough, but that’s just a personal aesthetic appearance thing -- probably some people think that looks cool.
