Yes, to your amp choices, and giving the DT880 a go would be a very nice choice, as it is very demonstrative of the Beyerdynamic sound sig.
If you really like it, consider moving up to the T1. I think spending the CHUNK of cash required by the T1, as a first trial, would be a mistake, in case you really don't find the Beyerdynamic ss appealing.
I own The Element.
It will power the DT's quite adequately, if somewhat clinically.
A tube amp mellows the DT ss very nicely.
