Not without some information as to what you require.
1-What's your budget?
2-Do you already have a TV/Monitor/screen or is this to be included in the budget?
3-Do you want surround sound, either 5.1 or 7.1? Or just 2 stereo speakers?
4-Which sources will you be using? ( CD, DVD, Games console, Sky, Sky HD, Blu-ray player etc...)
Answer those and you should get more response from this forum.
