There is almost always room for improvement on your sound, but some of the tweaks are ridiculous and some people "buy" right in to them. If you're looking for a huge improvement in your sound, as most of us are, I would suggest concentrating on tuning your room. You can have the best system, that money can buy, but if your room is lacking, you're wasting your money.
Is it possible to be an audiophile and be happy with what you have
It seems like audiophiles are always looking to upgrade. From something as minor as a fuse to upgrading all their components. Music lovers on the other hand seem content with what equipment they have and just want to experience new music. So I ask you, can a audiophile just be happy with what they have? Or is that just not possible being an audiophile?
