As a side note, being in Singapore will likely limit many of your options. You will, I guarantee, get lot's of advice on product that may not be easily available to you.
That said, have you done any shopping, yet? What is available to you?
Depending on your budget, there are a couple companies like Sigberg and Arendal in the EU that are producing some very nice gear that measures well, and they ship worldwide with all shipping and customs fees included in the price. I only list that to put it on your radar on the chance it
may make sense for your situation.
Yes...
Please tell us about your room and plans. What are your goals/what you would like to achieve?
This is a good place to start. As you get a little more focused, you can start new threads in the appropriate subforum for that topic, Loudspeakers, Amps, Subwoofers, etc...
Cheers!
