buy the sound u like, because listening is subjetive matters.
what speaker u using now? any unsatisfy problem?

setup playback is easy, aim towards perfection is difficult.

ok then, how much u plan to spend?
if u want surround, 1-2k cannot go far from htib set.
if u dont want surround, can look around hifi shop.

or just go get HTIB = home theater in a box

what different are you asking? do u mean compare htib to tv sound?

of course much better la from speaker pointing downward is too weak and lost balance.

htib set, got amp, player, 5pcs speaker, 1pc subwoofer, cable.

ht component set, u pick and choose the above items.
