I briefly owned the Klipsch Pro-Media v2-400s not too long after they came out. I got rid of them for the BA4800s, kept those for slightly over two years, and just recently got the BA7800s.
I felt that the Klipsch speakers had a large gap where the mid-range was suppose to be with shrill highs and boomy lows. Klipsch made a few corrections with the Pro-Media 4.1s by improving the mid-range, but it was still not up to par with the BA4800s. The BA4800s offered excellent mid-range, sufficient highs, and okay lows, though the sub sometimes produced too much port noise. The mid-range is where it's at, so I was happy with them.
The BA7800s took the BA4800s, enlarged the mid-range drivers from 2.5" to 3", added a .75" tweeter (on the front satellites), and included an 8" down-firing sub. The mid-range is still fantastic, the highs are there, and the sub is very smooth. The sub does lack some of the really low-end kick that some people want, but I prefer the way it is. Because of the crossovers, the system just blends together really well. I hear a lot more detail in the music than I use to. The BA7800s are also louder than the Klipsch speakers. Some negatives about the BA7800s: 1) can't use your own speaker wire, 2) no detachable control pod, and 3) no removable speaker covers. With that said, it's still the best sounding system I've heard for under $400 or so.
But, don't take my word for it.
3Dsoundsurge.com will have a review up of the BA7800s shortly.
