Hey, can we be a little nicer, AG members? Everyone doesn't necessarily have the same background or speak in the same lingo, but that's not a reason to be snarky.
Narcisco, To answer your question politely, everyone will have a different idea of what live music sounds like to them. Therefore, you must try out different types so that you find what sounds live to you. That said, there are many brands that are reputable and of good value, but this is also a hobby in which you can be ripped off if you are new to it. If something sounds good to you and you can afford it, that's the key.
