Its true, a turntable rewards tweaks like you can't believe. Your Project table is plenty good enough for you to know you love vinyl. Which is really something considering its a very entry level table. Getting more involved with setup and adjustments like effischer suggested will pay big dividends now and even bigger ones later on when you do buy your next table because you will know so much more what matters from actual experience.
The truth is what you already have is more than good enough so that all your most cost-effective upgrades right now will be tweaks, accessories, and adjustments. I'm not just talking about the turntable either by the way. I mean all of what you have. But that is only considering sound quality and sound quality alone. Because a lot of the most effective improvements are invisible. But how things look matters too, and more to some than others. So really it turns out that as important as it is to know the components its equally important to know yourself.
