That's very true, but remember that the VERZA is pretty much the only one that supports both iOS and a majority of Android devices out there (and Windows RT, if you care.) Of course for $600 amp only, then I will get the ones you mentioned anytime. In fact, I am very likely to pick up a ReMK3-B+ or HiFi M8 in the future.
The Verza is one of the handful of DAC/amps out there that can bypass the iDevice built-in DAC, and they are all in the same price range ($500-700)
