tvspecv:
if you use a 5.1 system like the
Panasonic SC-BT205 (home cinema in a box) without an amp an 5 speakers
will you achieve the same quality sound as when connecting an amp an 5 speakers its not rocket science!!!
Not rocket science, no. But your wording was a bit ambiguous
I had a Sony HCIAB for years, with 5 little speakers, a passive sub, in built amp and DVD and even a radio. It was a great little bit of kit and much better than the TV speakers for movies and TV sound itself.
However. When I had the money and I bought a Blu-ray player, an A/V amp and a surround speaker package all seperately, (yep, you even have to buy the speaker cables seperately). The performance improved dramatically (as you would hope for the additional outlay). I'm not knocking the Sony HCIAB (I gave it to my parents and they think it's the bee's knees). But it's a lifestyle product designed down to a price.
It's all down to how important quality sound is to you and how deep your pockets are. If you just want a bit more involvement when you watch the occasional film, you're probably not up for spending loads. However, if you're an ardent film fan, then you'll probably see a benefit in a greater outlay. Likewise. If you're looking at spending £300/400, there's no real point in looking at seperates. By the HCIAB and know you've got a great product for your cash.
