You also mentioned your only regret is that Beyer didn't make the DT1990s with twin cables like the Amiron. Does it REALLY make any difference ? When I see people write stuff like that, being a total novice, makes me worry that I shouldn't be getting the DT1990s (or any headphone without balanced cables).
Balancing is an interesting thing. The headphones don't care if they're balanced or not, but the amp is balanced all the way through, there can be advantages. A "balanced" signal is just a signal that has 2 signals, 180 degrees out of phase with each other. Having both signals means that the designer of the amp can use all sorts of cool, low-distortion topologies that sound subjectively better. Balanced topologies also have the advantage of having massive PSRR (power supply rejection ratio) so they can be very, very low noise even with noisy power supplies. The practical upshot of all of this is that running a balanced system can be advantageous, but just because of the amp section. Pairing balanced headphones with a balanced amp is usually a good idea if the amp has a balanced output stage, because you get the full output power (a good thing).
Mind you, all of this is purely theoretical, and a well designed single ended amp can be, and often is, better than a badly-designed or even mediocre balanced amp.
