Just my 2¢ - The Muse 9Sig was my single-component solution for 2ch redbook and dvd video front end. At the time of my purchase, the distance between mass market dvd/cd players and declared hi-end units were vast in quality and price. I think the 9Sig reputation of excellent sound and video continues because it's original targets for playback performance were very high. The cutting edge nature of the Muse designer and upgrade path for future formats made the Nine an appropriate choice for me.
I have heard the units you mentioned, although not in my system. The 9000 I haven't heard, but it is prized by many as well. I would consider the Muse character as being neutral and controlled. Not the most relaxed or fluid as I have heard, but very competent. Trust your own decisions about better or best. IMO, the Muse has a refined sound that elevates it above the crowd.
Good luck.
