I am looking to buy an All in one home cinema system for my living room. I have narrowed the choice down to 3 systems 1.Panasonic SCH520 Great reviews,but doesnt seem to upmix stereo from TV source and volume is a bit low 2.Pioneer DCS 222 Looks good ,sounds good ,multiregion 3.Sony DAV SB-200 Good system,lots of power,not multiregional,but has floor standing speakers which I like. I already have a DVD player and the most important factor in buying the system is the sound aspect not the picture. I want a good clear powerful system so I can watch lots of DVD's and upmix standard Tv. Anyone have experience of any of these systems or are they all good and I cant go wrong ?
