Very new to high end audio - Recomendations

thanks for all the comments! What are your thoughts on paradigm monitor 5 floorstanding speakers?

At some point you’ll outgrow active speakers due to its non flexibility. It could happen pretty fast, so my suggestion is to go class A amplification with high sensitivity speakers….pay a lot of attention to preamplification as sound signature depend on it a lot…tubes are preferred….be ready to do a lot of experiments (speakers positioning, cables rolling, power sourcing, room treatment etc..)  

Hello,
I am going to suggest the PSB AM5. These are a lot less than your budget. This is a lot of powered speakers for the money. It even has a built in Phono amp. With your left over money I would invest in a used subwoofer. Not to rock out but to get great sound even at low levels. Another powered speaker is the KEF LSX. These really rock plus come in cool colors. They are baby LS 50s. No sub needed for now and you have full capability but no phono preamp. $1000 is just under your budget and they just upgraded these so you can find the previous model for a few $100 less. You cannot go wrong with these two. It looks like you are in Europe. If someone else wants to check out these two powered speakers and several more and live in the Chicagoland area this brick and mortar has all of this to try out before you buy. https://holmaudio.com/
Later you can add the matching KEF KC62 sub that plays down to 11hz. Also, The big brother KF92 that also plays down to 11hz but 50% louder. KEF makes killer products. 

Knowledge is almost zilch when it comes to speakers/amps etc.

You’ll fit right in. [Sorry, couldn’t resist]

Most here are FanBoys. Ignore ALL specific recommendations. No one has your taste in music, response, level or R O O M !

IMO, powered speakers are a risk. They are convenient for recording engineers that move from studio to studio. I've never heard a pair that I’d want to take home.

You can fine tune separates with cables and amplifiers. FWIW, which is zero, I had the same speakers for 35 years and 5 different amps and about the same number of cables for both interconnect and speaker. [Truth in advertising dept: Speakers were Spica TC-50 and I place coherence over frequency response six ways to Sunday.]

Since you referenced quid, search out some High End HiFi shops relatively close by. [Distances are much less in the UK than here in the US.] Time spent now trolling the waterfront will keep money in your pocket later. If you are in one of the bigger burgs, there may be a HiFi or Tube society. Worth checking out.

Bonne Chance!

Knowledge always starts from the beginning :)
