I've had a couple of Schiit amps, the Asgard 1 and Magni 1. Thought the Magni was great for the money and gave a very honest reproduction, maybe a little hard sounding but good for warm hp's.
The Asgard was more refined and sweeter sounding but a little too brightly lit at the top with some hp's. I couldn't listen the K702's very long with that one.
I think the Schiit line up offer great value for money but they are not what I would recommend as 1st choices, as I think there are better amps for the same or a little more money. I would recommend the M-stage over both of them and any of the Audio gd midrange (they do opamp design very well) with the Kxxx
If you do like a warmer powerful/dynamic sound sig you could do a lot worse than dipping your feet in the world of vintage amps. The AKG's play very well with the high impedance and power of the 70's designs. Pioneer, Sansui receivers/amps from the mid to late 70's and NAD amps from the early 80's are worth looking at. Although the prices are increasing now you can snap up some bargains if you put the work in.
Heres a few pics from some of my collection.
