I own A7's in a 23 x 13 x 8 room. I would think that the A2's are too small in that room. (Aside: I am upgrading to D7.2's this fall).
My only other comment is that I am surprised you got boomy bass from a combo of the A4's and Hegel H90. I have also owned Hegel and their overly damped design seems like the last thing I would pair with Spendors. I am not a fan of Hegel amps in general but I would think that they are best paired with speakers with innately poor bass control.
