Silverline Sonatina IV

I have recently acquired a pair of the tiny Minuet Supreme Plus monitors from this company and love them! I am trying them out side by side with the PSB Imagine Mini's and so far prefer the Silverlines through my Audio Research CA-50 integrated amp, though I've only had the speakers for less than a week. I am in need of another pair of speakers for my bigger listening room and wonder if the Sonatina IV's would give me a similar sound signature to the tiny Minuets? The large listening room has BAT amplification (VK55SE mono blocks and VK32SE preamp). The Sonatinas do not need that much power at 91 dB sensitivity. Any thoughts on how the Sontatinas will sound with my BAT stuff? As sweet and pure as the Minuets? Currently I am using ProAc D13s with the BATs plus a REL Storm III sub, and the sound is good but not great. I am still working on setting up the sub properly in the room. Wondering if the Sonatinas would be a better match?
