If your wife is referring to imaging keep in mind electrostatic speakers image incredibly well better than most conventional box speakers. So possibly just the difference in presentation. Though obviously also as suggested above there are ways to improve your system.
Musician vs. audiophile
We need direction here. My wife, a musician and says my Sophia 3s, powered by BAT 3VK IX tube pre amp and 250w solid state amp sounds flat compared to a freaking Best Buy box store
McIntosh/Martin Logan setup... I can't honestly disagree, specifically when our rig is at low volume. It lacks color and punch, even with 2ea. JL 12" subs... Help me with your recommendation, please!!!
