Bigjohn,
Thanks for the response. As far as I understand QS4 will be every bit as good as QS8 for HT. The only area of difference will be DVD-Audio/SACD. If I were to play bass from surround channels through QS4's they'll be lacking due to the less bass response. In that case, though, couldn't I just re-direct bass to the sub just like for video DVDs? I read there are some shortcoming with that (in case DVD player cannot do it). Is that true?
