There are many factors for a "great" sounding table; scrutinizing adjustments is one of them.
The most important factor is the cartridge for you; initially you should buy the cheaper cartridges, and when you like one brand over another, buy one in the vicinity of 1k in that brand; this is for a long time, you won't regret it. Cartridges in the vicinity of 1K are very competitive, meaning they're all good, but in different ways.
I have a Grado Master, it's for jazz and female vocal, not for rock. Experiment as much as possible.

This is a good table, tweaks and the right cartridge can make it a great table; I have one that's tweaked out and it really sings; sounds better than class A digital.
