Z5500 does sound great, but is really overkill for home use. The Z2200, 2300, and whatever replace that is more in line with the sound bars. I've had a 2200 in my office and a 5500 for living room theater sound for years now and they both work great.
I finally sold the 2200 I kept for small jobs and backup after I got the HK earlier this year.
The sound bars remind me, in looks only, of the optional speakers system for PA3x.
