The answer is NO. 90% of sound quality depends on your room - 95% of people don't have such a special room...(non-residential rectangular room with concrete or brick walls, heavy and hard wooden floor, sloped ceiling)...
Plasma TV is the most analog picture - the most fun, more like film ... but you will not find a panel of this size now ... You can find a projector, but a quality screen will cost 5 times more.
Films with effects - they are made for children ... an adult serious movie - even mono sound is enough for him - a goavy plot and acting.
If there is a good movie (for example Avatar 1) - visit IMAX ...
Do not throw money and time out the window = life is short!
I saved you a lot of money - visit sick lonely people - they will be very pleased, and you will make your soul better.
