I have the same speakers and the 509X and like the combination. It all depends on the sound you are looking for and the budget. I would categorize the sound as very neutral with crisp, yet smooth highs. This combo should not sound harsh. This pairs well with the 11As since they tend to roll off highs. It has very controlled bass but not as big as the m900u and some much higher priced alternatives.
I would skip the M700U since you get basically same amp in the 509X. I heard the m900u paired with the 11A at a dealer and it was fantastic, though it sounded best with the matching c900u preamp. Not sure how it would sound with the Primaluna.
I am a big fan of integrated since it saves a lot of time and money on matching components and cables.
