I'm looking at buying the AKG K702 Reference Open-Back Over-Ear Studio Headphones and was wondering if I need a DAC/amp and also if there I a better headset for that price range ,these will live on my desk and don't need to be portable.
Yes your B350 Tomahawk has higher quality audio components and headphone amp.
Should be just fine
Thanks for that also do think that thoughs are a good choice of headphone these will not be used for audio work but more media and gaming
Headphones is not my area of expertise, I personally don't do anything that warrants high end headphones for PC, and my clients are all business professionals so it is not something that I have researched on or have any experience with.
