I'm going to be spending around this price range. I will also get a good DAC so that isn't a huge factor.
I've seen good reviews of the Airmotiv 6's but I can't really find Much on the F! F7 is fairly new and I can't find good comparison reviews. There a few on audio sites and some bad youtube reviews.
I loved the A7X when I heard it in person. It blew me away, however I can't afford them it's just not happening even the A5X is out of the range. The few reviews I've read are mixed.
It also really sucks cause I just missed the Airmotiv's being on sale by 2-3 days, I will wait for the factory sale if I have to, but they come out to $700 so a decent amount more if you don't get them on sale. The F7 is $400 only. If I wait for factor sale I can get Airmotiv 6 @ $550 and the Airmotiv 5 for same price as F7.
