Very new to high end audio - Recomendations


Hello, as the title says etc etc.
a few years member of headfi and enjoy my personal mobile setup, but looking into something for the home. This site was suggested as a nice place to look around in.
Knowledge is almost zilch when it comes to speakers/amps etc. 
I'm thinking maybe active speakers and I can line out from my DAP, will that work? How do active speakers perform best? what would work out better if matching prices in active speakers or passive with an amp?
Budget is fairly low, max £1000. Something to introduce me into the scenery. Something nice secondhand (preloved) or if a nifty setup can be bought new at a budget along those lines. Thanks in advance for any suggestions :)

Used of course, from trusted seller. Active speakers are a good way to keep the cost down and get great sound. Not as easy to upgrade, so just sell them when you're ready to spend the big $$. 
I had a listen to some KEF ls50 meta today. Sounded quite good. For less money they also had some monitor audio silver floor towers. Didn't have time to listen to them though. 50% though..
A colleague has a set of Kef Ls50's, I think driven by a Musical Fideloty amplifier.  I felt the bass was amazing for such a small speaker but I thought the highs were too sharp and biting.
I felt they lacked mid. But could also have been whatever the amp setting was on. I didn't play with the amp
