I picked both of them up a few weeks ago. I don’t have the ad2000
(anyone want to sell me one?) but I do have the adx5000 and if you’re a fan of that brighter signature, definitely the AWKT. It is overall the most detailed of the two and to my ears is like a closed back 5000. the AWAS is way more fun though and one of the smoothest headphones to listen to and has honestly captured my heart. It reminds me of the LCD-5 in that it’s perfectly balanced, no extreme bass or highs, but with a swathe of coloring thrown on top making it feel richer, more dynamic and musical than the 5 which comes across to me as somewhat boring, mechanical and sterile. That said the AWKT is also a relaxing listen but those highs will kick in badly recorded tracks, but if you do get a good source it will really shine. I also disagree that it doesn’t work for rock/pop/hip-hop, the bass will growl when it is needed so it’s not a total snooze fest. 2001 by Dr. Dre still manages to thump well with good vocal presence, you’ll start deciphering lyrics that sometimes come across as mumbles in other headphones. I imagine it would be a good TV/Movie watching headphone if you constantly find yourself wondering what the actors just said! It’s really fun on ASMR videos as well, you’ll think the person is right there with you and with that natural wood sound, tapping, clicks and thumps all sound realistic and not digital or processed.
This is why it was so hard for me to pick one, they both have their strengths I just had to have both

but fair warning they are more closer to each other than they are different even down to sound stage, so if you only have the budget for one, decide which is more important, detail clarity or a more relaxing sound, that is essentially the biggest dividing line.
