I'm gonna be buying new headphones, and i'm looking at the DT990's (manafaktur cause i love the colours and they look too drab otherwise) and now the T70p's. Now i know that ordinary 32 ohm DT990's are like $250, and the T70p's are $550. So that's why i wanna buy them used for around 430. So, which ones would be better to buy? The DT990 Manafaktur's (go upto 400) or the T70p used ONLY (for 430). I listed to electronica, Rock, Metal, and that's about it. (maybe a little but of movies though) Also, the maximum amplification i think i'll be using is like an E6. So please, enlighten me!! Also, i know that it's closed vs open, but i didn't mind not having isolation with my current HD555's, so that shouldn't be an issue. Although, it would be a plus point to have some.
