I bought the Z11 on first release because I had a DSP-1 and really like the soundfields. It's in use in a dedicated home theater and I really wanted the new audio codecs and HDMI switching. I find that I am only using the theater for movies and running in THX mode, so the extra 4 presence speakers aren't doing anything in that mode. So, in perfect hindsight, I would have been better off to have waited to buy the less expensive Z7. It does what I find myself doing all the time. I'm just not sitting in the theater listening to music.
