Anybody heard the T70p and DT990?

I have the DT990/600 and T70(250ohm). My review will be out in a week or 2 but they sound different of course (open vs closed, tesla technology,...) yet both have the "bright" Beyer signature

I've got both the T70p and the DT990. I'm loving the T70s. They have great separation and sound stage (for a closed can). Imagine the detail of the 990, but with the bass and treble evened out more. It sounds a lot more neutral. Not to mention they are insanely efficient. No need for an amp, I found that they sound much better without one in fact.

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.
