Hiya rgutierr, hope you are both enjoying the hobby! If you are not fully in yet, what better excuse is there but to demo equipment.
To answer the question quickly- more power does not always equal more money.
Plenty of DAP’s nowadays have enough power to work with headphones (with the exception of a few really demanding ones).
It really just depends on which headphones and what your budget is for the DAP. You can use something like this calculator to find out how much power you need to drive the headphones you are looking for (look at the Vrms figure and add 20db to the level you would normally listen at to adjust for some tracks which have lower dynamic range and you need more power for - those tracks you end up needing to put more volume up for):

With that knowledge you can then look at which DAP’s have enough power to drive those headphones (what their maximum output is). And a key spec to look for is single ended (3.5mm) output & balanced (4.4mm) output - as it depends which one you want to use with the headphones (what their stock connector is).
The biggest factor being budget range. Think of how much you want to split between the headphone & DAP.
Ah, also if you run into mW figures for DAP output - this might come in handy, check the resistance/ ohm rating of the headphones and then the conversion would roughly look like:
“
rHead specifies 2,000mW into 16Ω (5.7Vrms), 1,100mW into 32Ω (6.0Vrms), and 130mW into 300Ω (6.5Vrms).”
