Right now I’m pleased with my set up, but I would love to get more pairs of headphones over the next couple of years!

That’s awesome! I got my HD8XXs for 900, but I actually got my ADI-2 for 900 and some change! Huge deal that I got from Sweetwater and it was brand new :)

I saw a couple reviewers state how the EQ on these is worse than the normal 800S, but I agree with you on the point that changing the pads on these helped tremendously! I changed the EQ to resemble the normal 800S but with more emphasis on the lows. I like bass and I listen to a lot of hip hop! ( I’m better off getting some closed back headphones I know) BUT I love the sound stage on these and it makes listening to music a BLAST!!

Also yes, it’s a dac/amp

In terms of long term I would definitely recommend this! I’ve had this set up for about 4 months now and it’s amazing. Not hard to set up either since it’s all really basic stuff. I do recommend reading the manual and looking through it as there’s some really interesting and cool things in there tho! Not sure how to describe it, but the way it’s written is really cool I guess?? I’m not sure how else to describe it. It also comes with a cool little remote.
