Maybe a PS Audio Sprout with Elac B6s? Well under budget ($799 for the whole setup including speaker cables) and should be extremely easy to transport. Both get rave reviews for the price. You can just bluetooth from your phone or add a chromecast audio and still be well under budget...or add a better streamer like the bluesound node 2 or auralic mini and be a bit over. From everything I've read the Sprout would be great for a bedroom or office system down the line too, but I admit I haven't heard one myself yet.
http://www.psaudio.com/products/sprout-elac-system-2/If you go powered, I've had great luck with Audioengine and they have a 30 day return policy if you don't end up happy with how it sounds. If you go for the HD6, you have built in bluetooth or about the same money left for a separate streamer as the option above...no phono input for down the line setups if you're into vinyl but they'd probably also be great for a secondary system if you don't need that or have a separate phono amp.
Another difference that may or may not matter to you is the HD6s have a remote...the Sprout does not.
The Outlaw (plus a chromecast) or new Yamaha integrated amps/receivers (i.e. R-N803 or A-S701) would work great. More powerful and more connections available but not quite as portable...Go farther down the yamaha lineup and more can be spent on speakers but the sweet spot in that balance is up to you. Did you like the Elacs when you heard them?
