In my experience with the DAC2, I preferred the Benchmark DAC1 to it. Therefore I'd agree with Jazz in stating the Opera's DAC is at least a bit better sounding. I think sizewize you might be at about a draw, since the Opera isn't small, but it might have a slight edge on total weight. Considering that it comes with a form-fitted box, it should be pretty easy to transport.

EDIT: I forgot to ask that can you hear that background hiss in Opera with full size low impedance headphones like Grado's?
I'd give the Opera the edge for soundstaging (and perhaps detail, if you take the larger soundstage to be indicative of more resolved high-end detail). Neutrality vs. warmth is a bit tricky because of the HP100's filters. The warmest sound is the HP100 w/filter B. The most neutral is the Opera. I generally found the Opera to be a more involving and enjoyable listen. Again these are virtually completely due to the differences in the headphone amps, as changing from the DA100 to the Opera's DAC made very little difference.
I could only hear the hiss with my UE IEM's. Even the W5000 which is more voltage sensitive than Grados did not show any hiss.

I've only heard the Opera with the headphones I own, so no Grados or Senns. Sorry!
