Yes, welcome to the VSA world. As you review possible equipment changes, the VR33 or VR35 speakers perform well with an amplifier with high damping factor (low output impedance). This will allow the amp to maintain a more vice-like control of the bass driver, resulting in tight, high bass resolution.
As you look at speaker placement, these speakers are designed to perform well when placed close to the front wall. If you have the space to move the speakers further away from the front wall, that wall coupling can be mimicked by placing a rigid vertical object behind the speaker at an optimum distance. This could be a butcher block cutting board, cement blocks, etc. This isn't necessarily better than the placement near the front wall, just an option if you want to experiment.
I hope this is helpful, enjoy.
