zufan, last spring I bought the MoFi SP 888. I'm not familiar with the other models on your list but feel confident in recommending them.
There was lots of information online when they were introduced but little since then. I'm not sure why except that often seems to happen.
For me they look great (felt fortunate to get the white cabinets), were easy to place and drive, and I've had great musical enjoyment with a wide variety of types. They are nearly full range (no, not down into the 20 Hz range), have great tonality, and are easy to listen to for extended periods of time. Some of my best recordings have startled me with their "in the room" presentation.
At the very least you owe them an audition.
