Can you plug that guitar into an amplifier too?
I agree with what Sebast is saying: there can be guitars that are in the average price that sound like a 1000$ guitar and you should to try several guitars before making a choice, don't rush. There are other things that you wanna consider, other than the quality of the sound, that is how that guitar is comfortable in your hands, for example, the size of the body and so on.
These things can be very personal. Make sure the strings are new when you try a guitar, because that will affect a lot the tone and sound.
