Ok, so I've order a pair of the TH600's and I've got an Modi and Magni coming I know it is very modest amp and dac but I will maybe upgrade in the future if need be. My current best is the V Moda M100. I chose the TH600's based on my music taste (posted in another thread) and the recommendation as well as many reviews. Kind of buying blindly here but I'm sure I won't be disappointed. Should be here at the start of next week.
I hate to be the bearer of bad news here but the magni + modi is prob. going to be a bit on the bright side for the th-600. If I were on a budget I'd go with the odac (rca ver.) and meier corda rock with a quail 14 awg power cable and some ela rca ic's. Just my 2 cents.
