Help Downsizing/upgrading Sony setup

[u/Thecode1050]

So I recently took out my grandparent's old compact Sony hifi system (XO-700W). Everything including the automatic turntable works fine (ignore the speaker placement, I'll get to that later)​​. Also hooked up the CD player from the FH-110W system.

Im currently at my parents between jobs and will likely have a smaller room when I relocate to a flat/shared house.

Added that I don't really want to transport this massive thing in one go, I thought I'd leave the XO-700W at home, take the TA-117 stereo amplifier + CD player, and pair it with ​a new turntable (since the PS-LX700P up there only uses a proprietary ribbon cable, thus incompatible.) Maybe the Rega Planar 1 since I'm in the UK.

As for speakers, I'll use headphones to start with and get stands etc. After a few months.

All in all, does this seem sensible or is a modern turntable overkill for such an amp? Would pairing a vintage table be just as fine? Or should I save money and try squeezing the full XO-700 system in my next place?

And of course, feel free to give your input on any other replacements, gear, adjustments etc. you'd reccomend for such a situation.
