Different sound need and goals. The home office combo audio/2ch HT system has an integrated amp, turntable, tuner, tape deck, VCR, and has a Stan Warren modified DVD player, so it works well with music and for movies when going to the Sony TV.
The HT system is modest but does the job; Onkyo HT receiver, B&W 302s all around with CC3 center and a REL Q100E sub; plus DVD player, VCR and a Laserdisc player.
The Audio system is too complex to list in detail. It is by far the best of the bunch.
I believe the Champ is Jeff in Montreal with 5 systems at last count. (I suggest he needed one in his bathroom too #6).
