Congrats on your purchase! Yeah, those cans are so fundamentally different, there are definite tradeoffs involved in the decision. IMO, the synergy with the Compass and D2000 is really strong, I've been very, very pleased with the combo. Plus, the Denon's are a solid "all-arounder" can to have in the stable. I have not heard the K701, but the feedback I've read about them with the Compass has been positive...
