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 :)

For that thousand pound budget, try some used equipment first. You can always sell it if not to your taste. And, james633 has a great idea: JBL sells at deep discounts all the time (my son scored a pair of Studio 570 at 50% of retail, they sound very fine with a stack of Carver from the 1980s: C2 pre, m200t amps monoblocked, Schiit Modi3 and laptop source). 
I didn’t realise JBL made decent gear. Where I come from (Australia) JBL is very popular in the mainstream electronic entertainment chain called JBHIFI. JBL products flooded the shelves with crappy portable bluetooth and headphones/speakers aimed at the average consumer who listens through music with their iphones. Is this the same JBL?

What makes a 'loudspeaker' any different to a studio monitor, or bookshelf etc, they look basically the same?
What makes a 'loudspeaker' any different to a studio monitor
I'm not a pro but a monitor generally has to fulfill a number of criteria. 
1. Flat frequency response within its range.
2. Small enough for close in use so the sound imparted to the engineer is not caused by room reflections etc.
