[PA][HELP] Possibly buying AKG 702, need dac/amp advice.

Hi all,

Was beginning to get overwhelmed looking at all the different posts and combos, so I thought to be safe I would make a post here. Thanks for your help!

Budget - Max of around $200 AUD ($400 USD) for the dac/amp. Please note that I do live in Australia so if that could be kept in mind for shipping that'd be great

Source/Amp - Currently plugging directly in to my Gigabyte Aorus b365 M motherboard. Have been considering the Topping A30 + D30, FIIO K5 PRO, or a JDS labs stack though importing is not ideal.

How the gear will be used - I mostly listen to classical music, the 702s apparently are great for this and have heard they are comfortable. I also play a lot of games but don't need to know what type of shoe is making the footsteps in an FPS. This will be solely used at my desk so no need for portability.

Preferred tonal balance - Balanced is good I guess? Whatever is ideal for classical with standard listening (Youtube, movies, games etc.).

Preferred music genre(s) - Classical.

Past gear experience - I have a pair of ATH-AD700 which were my first jump in to higher end audio. While I love the sound they provide I've struggled with comfort when I am using them for extended periods. Possibly have a weird head.

It has got to the point where I've put them away and am just using a pair of earbuds. These have helped me decide I really want to improve on the comfort side of things and the AKG 702 seem to fit the bill for this.

What aspect of your current listening experience would you like to improve? From what I've read I definitely need a dac/amp that can run the AKG 702s. While I have read that while they don't need a lot of power, impedance levels can be an issue?

Thanks in advance and if you need any more info please let me know!
