New Gallo Strada 2's - need surround advice.

As a Christmas gift to my wife I decided to severely downsize my gear. Selling off my ML Ascents and Logos, and ancient ULD-15, sold my amps and processor in favor of an Anthem MRX-510, acurus 200x3 (for fronts), three Gallo Strada 2’s and a TR-3D. Will be getting a second sub once I recover from the expenses, or the speakers sell.

Anyway, been using a pair of small Monitor Audio bookshelves as rears for HT purposes. Have them on the floor facing up. Awful positioning, but I can’t hang black boxes on the back wall. So I’m thinking of switching to either the nice small, white Gallo A’Divas or Nucleus’ for the rears. My question is, does anyone have experience with either the A’Divas or Nuc’s pairing up with Stradas? Wondering if I can get away with the less expensive Nucleus’s for surrounds. FYI it’s a small room, prob 14’x 18.

The Stradas, btw, are actually a better sounding choice for my room then the Ascents, and the second sub will be the nail in the coffin. They keep that fast and clean, electrostatic sound I love, and add amazing, almost "holographic" imaging, in an incredibly room (and wife) friendly package. They are awesome, and not even fully broken in yet. Every few hours they open up even more. Love them.
