Advice on second camera

I have sold my Nikon D7000 kit and bought a Panasonic FZ200 mainly for its zoom range. Now I am planning to buy a second "compact" camera mainly for "quality" photos and indoor parties, museums or travel photos. Budget is around $600-700. I have considered the RX100 and LX7 but would prefer a m4/3 camera with a bigger sensor. EVF is not a must but would be nice. I shoot both JPEG and RAW. I do not print photos but just watch them on the PC or TV. What would you recommend?
