Do you really need an integrated? Many people don't. I use my DAC as my pre and VC when I don't have my Transformer VC. I do have 2 inputs to my amp so I can also use it with HT.
If you don't really need an integrated, a simple point to point amp like the $1200 Decware SE84UFO will blow away any of the other amps you are looking at and is plenty of power for those horns.
Aric and Apollo also make great amps.
