Hi aram535,
You could try it without a Hiifiberry or other DAC. You will then need a Raspberry Pi 3B, this is the only current model with an audio output connector. It will work and has a surprisingly good audio quality.
Once you have everything working you can then choose to buy an add-on soundcard. You will certainly be able to hear the sound quality difference.
You could also choose a low-cost route using a Raspberry Pi Zero with an add-on soundcard. The Zero has no audio out connector, no wired ethernet connector and only one USB port. This means you will need to buy several other parts to complete the setup and be a bit of a hobbyist to get it all working.
About the sound cards (HAT DAC's, USB DAC's, etc.). There are lots of different models to choose from, search the forum for 'DAC', most are mentioned. Almost all are very good quality for the price you pay. Cheap Chinese cards are generally not as good as those from named suppliers. In general, you get what you pay for.
