Hey Macct.
You're pretty much ruined if you have heard the SCm20's as you have heard there are not too many speaker in its class.
I Know the Krell HTS will be fine with the 20's you might want to play with some cables to get it perfect but otherwise I wouldn't worry about the sound being too aggressive. The 20's don't image artificially so don't expect them to give you a break with a diffuse distant deep soundstage created by response shaping, I always tell people you better like your music if you buy an ATC speaker because its not a presentation you can easily ignore. Very involving and demanding.
