Check out this (excerpt from an) article here:
It's not about the quality and the price that you pay for the gear. It's a system you're placing inside of another system. And the system you're putting it inside of -- your room -- has far more influence and impact than the speakers and amplifiers on your sound. This is what people don't understand. They think that if you buy a new amplifier or a speaker, you're going to get better sound. Now, if you put it in the same room, you're going to get a different sound. The word here is different, not better. Do you really want to spend all that money for just different? The room has all the control, so spend your money on fixing the room first. You don't need to spend so much on electronics. Keep your speakers and gear and fix the room. Just spend 25% of the budget you spent on speakers and gear, you'll get a 250% improvement on sound quality. That's a great cost-benefit ratio. When you buy new speakers and a new amplifier without first addressing room acoustics, the room just laughs and says to itself, "Oh, another speaker and amplifier, let's see what we can do to mess these up."
