‘Upgrading’ a hifi set up

In my lounge, I have an old turntable connected to a Technics amp as well as a pair of passive speakers. In the same room, I have a Playbar and two Play Ones connected by optical and WiFi system to the TV for a ‘cinema setup.’

I want to get a better turntable and speakers so I’m wondering what the best way of doing this would be:

1. A new turntable connected directly through line in to two Era 100 speakers (I think 300s would be overkill for a 18 foot x 10 foot lounge?) which would replace the Play Ones. Saving space would be desirable.
2. A new turntable connected by BT to two Era 100s (could they act as TV speakers as well? Would I still need the Playbar?)
3. A new turntable, keep the amp but replace the speakers with better ones. 

Lots of other ways of doing this but my priorities are improving sound and using less space.

I would be grateful for any input (so to speak!)
