I want to buy k701s in the near future but also want to buy a dac, most likely the dacmagic. I have ad700s and should I buy dac then k701? Or is a 400$ dac pointless for an 80$ pair of hps like I've read about? I know for sure I'm going to buy hp then dac or other way around and then buy an amp to get some bass out of the k701s later on. I listen to a variety anywhere from Claude Debussy to Jay-Z to Gorrilaz etc.
