Beyerdynamic DT770 80 ohm
Best out of the ones you mentioned. Will work great out of your Onkyo HT. Your music taste are the same as mine, they work well here. Best comfort,Build and sound of the bunch. Some people say they are V-Shaped. Not really, actually quite balanced sounding.
It has nice hard bass but only when it's called for, Very detailed mids and highs that are smooth (Senn like but better sparkle), and one of the best sound stages in a closed can.
The AT 50,...
