I was in your position 2 years ago. I think it depends on where you are coming from and where you are at. Assuming you're youngish with some years of earning $ to go, I would not hesitate to start smaller and take some baby steps. Don't get caught up in the "you have to spend $3000+ to get real sound" nonsense, it would be pointless in a small apartment. If you're used to basic to medium quality audio products, a step into intro-level audiophile products is going to be a big upgrade, and then you can just build from there.
Some products to consider:
Kanto Audio - TUK powered speakers
Outlaw Audio RR2160 - An integrated amp with good clean power and plenty of room for growth
Monitor Audio - The Bronze line of speakers are fantastic for the price
Meridian Explorer 2 - A pocket USB DAC that will also fully unfold MQA audio and hi-res streaming
