Im not sure what I want I am upgrading from HD595's and im looking for some more bass & better soundstage/ instrument separation.
Now here's the complicated part I listen to folkrock, electronica, melodic death metal, post rock, Blues, Prog-rock, Desert-rock and some dubstep.
After some serious reading around im confused about the HD650's relationship with speed? How do they do with prog rock/metal (Tool, Ping floyd, Jethro Tull, Monster magnet?) or can they handle InFlames?
I bet they are brilliant for blues and wood/strings but do they get muddy with speed/ish music?
So I dont want headphones to tire me out and when i moved to HD595's I was stunned with the soundstage (Pink Floyd - Southhampton docks) also I liked the airiness and as it turns out they arent considered to be airy or with great soundstage but rather quite upfront headphones from Sennheiser. I would like to get some more bass impact (just a little bit I dont want overwhelming bass but I want it to be deep and impactful - if that makes sense) im a bass-head to the level where the bass does not ruin the whole sound but rather complements the soundpicture without destroying it. So if I could find something in ~400 USD range that gives me:
-More separation
-More Bass
-More Detail
Also I am extremely curious about AKG 701 and Beyerdynamic DT880/990 but after Beyer released T1's I feel that I wont bother with DT's anymore and get T1's when I feel comfortable with the expense.
Im thinking that AKG 701 could be brilliant phones but im afraid they might be fatiguing and lack bass? Also what is the difference between AKG 701/702?
Could my warm Morgan Jones Tube amp compensate for the lack of bass in AKG 701's?
If someone could answer few of my questions id be really happy.
