I have a great stereo system and great separate home theater system, also a large screen TV with high end sound bar in the bedroom. Obviously a separate system is preferred (a TV in the middle is usually acoustically bad)... I would personally add a really inexpensive surround system to the TV and keep separate if possible. For HT I am so distracted by the video, and the 3D sound effect so much an improvement over none that SQ is not nearly as important in that setting. However, you may have to for various reasons.
It has been a long time since I assembled my HT. It is composed of top of the line Meridian surround processor, 5 matching B&W 805s, 2 B&W 800 subwoofers, and a massive Rotel amp. It sounds great. If you are going to combine them, make sure the processor is as high end as possible and has a bipass. You don’t want your sign going through any digital processing. Good luck to you.
