Kr4, For many people it is a choice between good two channel system and less than average multichannel for the same cost.
How much better speakers I can afford when buying only two. How much better amp I can afford when it is two channel only etc. There are also living space constrains that can make multichannel system far from optimal. Would I invest a lot of money in multichannel when all my CDs are redbook. Not practical for me. I understand that multichannel recordings are not that popular. That's perhaps why somebody mentioned home theater system as the main use.
