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 :)

Active speaker are fine and you can run them as stated above. I can’t really recommend any as I have only used a few. Most people on here use passive speakers and separate power amps to tune the sound a bit more. 
Paradigm  
kef
Dynaudo
ATC
focal 
B&W

are all highend brands that make good powered speakers with Focal and ATC targeting the studio market. Headphones are pretty good these days so just any old cheap powered speaker will probably be disappointing. What headphones do you use and like?

As passive speakers that are a lot of good used deals on here (audio mart might work better in Europe). Even a modest setup will be more enjoyable than headphones IMO (I have a bunch of headphones too). The speakers just have way more soundstage and presents.
