How does the Bass of the HD800 and the T1 compare to the D7000?
The one thing I love about the D7000's is they are the first headphones I found that could even come close to producing a bass note like the JL 12W3V3s I used to have in my car did.
I really want more full mids and perhaps a better soundstage, but I don't want to sacrifice a ton of bass to get there.
I also wouldn't mind headphones that didn't make my ears sweat, but that's a secondary concern.
I'm also considering just doing Amp/Dac first since it should help the D7000 now, and would make a world of difference with a lot of the better headphones out there. With that I'm more torn about how big to go, balanced/unbalanced, separates or combo, etc. I'm very curious to see the reviews of the new schiit balanced stuff. I guess if I decide to go that way though I'll make a different thread in the appropriate forum.
I'm also curious about how well the D7000 take to recabling/balancing. I understand a lot of people like the MarkL mod, but the idea of filling my headphones with dynamat just seems wrong to me somehow.
That's tough requirement. As nature of closed cans, D7000 has a lot of bass that open-aire cans cannot produce.
You are not going to get same quantity of bass of D7000 from either HD800, T1 nor LCD-2.
HD800 is very slightly bass-light for average headphones, so it is out of question for people who like bass.
T1 has a lot of bass yet very tight compared to D7000, and LCD-2's bass is between HD800 and T1. LCD-2 is probably the most balanced ortho/dynamic headphones you can buy (I dislike LCD-3 so I won't comment on it)
I see you are basshead... Beyer T1 is the safe bet for you. T1 has both good bass (tho not much as D7000 in quantity) and amazing high (while not as good/balanced as HD800 and LCD-2).
That say, HD800, T1 and LCD-2 are just far better headphones than D7000 (with higher prices as well) in general, but you won't want to get HD800 if bass concerns you. If you want closed headphones, Kenwood KH-K1000 is also good choice since it is a bit better than D7000 while it is actually cheaper to obtain as well.
