I reckon I'm pretty much there with my system, but I'd appreciate some thoughts on where to look to get the best out of it.

My highlights:
Successfully finding and bringing back to life the Thorens Ambiance, although I think it probably needs a better arm cable (Siltech or Chord most likely). I'll also look to replace the armboard as the original is warped. It needs an RDC record clamp and I'd like to try a Funk Achromat (5mm version) in due course - both will have to wait until they turn up secondhand as neither are made currently.
The TD521 needs re-veneering as it looks a bit tatty; a job I can do myself given time.
Sorting out the network to the streamer. Rather than using wi-fi, I'm now using a cable plugged into a range extender.
Replacing the tweeters on the Ruark Equinox speakers after one blew made me realise how much performance they'd lost since new.

Thoughts and opinions needed on:
Mains power distribution; what are people using? I'm currently using a Moth Audio kit I bought 20ish years ago.
Network for the streamer; do filters/re-clocks/cables make an appreciable difference? Any good ones to look at? I'm currently using a reasonable quality CAT-7 cable...
Anything else?

Cheers,

Steph
