In regards to the staging and “clustered” sound…I agree with what everyone else has said in regards to minimal improvements from amp/dac upgrades and the other advice given regarding recordings, speakers etc.
I did want to add some of my observations since I have these headphones also.
First the Clear sound clustered to me too. They are intimate and forward. They sound shouty and claustrophobic to me…not my favorite. To each his own.
The HD800S though are another story. They and the Arya have been my 2 favorites up until recently getting the Susvara. I would switch between the 2 depending on what I’m listening to. To me the 800s is great for orchestral/classical because even though it does have great stage and imaging, it is a more natural sound. More like what you’d hear at a venue. Where instruments are clearly in their “space”, it’s more a general area and things blend more so than on the Arya. There’s more space around instruments with Arya. They are still clearly defined and you can easily focus on something and follow it but it’s not “pulled apart”. I love this headphone for certain music/moods.
The Arya also has great staging and imaging. What a lot of people dislike about them is how separated things can sound. To the point of being described as torn apart. Which I have found is quite dependent on gear pairing/synergy.
Compared to the 800s, things are still wide and open but there’s more space around instruments. Where you can close your eyes with 800s and say “the violin is over on this side and up here” . The Arya is much more pinpoint…the violin is in this exact spot. More pinpoint where 800s is a broader image.
This headphone was my favorite till the Susvara. I love the clarity and separation. With the right synergy I think it’s pretty awesome. Movie soundtracks, electronic, ambient and others are fricken great on this IMO
My first Dac/amp combo with it wasn’t great…actually it really sucked.(smsl su8 +thx 887) It made everything dry and clinical. It had absolutely no soul to the music.
All this is to say you might try a planar headphone. Maybe it will give you that separation you’re looking for. Keep in mind that all the previously mentioned things apply as far as recording quality, genres, gear synergy blah blah blah.
In my opinion these 2 headphones are a good complement to each other.
Also, as you seem like you’ve caught the bug like the rest of us and are in it for the long haul… I would suggest hanging on to your headphones as you move up the gear ladder if you’re able to.
I’ve been surprised at the changes/synergies and scaling certain headphones are capable of as I progress up the chain. What you didn’t initially like you may with your next change in setup and you’ll learn what attributes are important to you.
Enjoy the journey
