Well done buying the Simon Yorke. Did you buy it from Simon or in the after-market?
I have an S4 Zarathustra (suspended). I had an S7 bought from Simon; then upgraded to an S10 with Aeroarm (parallel tracking on air bearing) bought from Simon 11 years ago. This plays wonderfully. I am told mine is one of only three customer Aeroarms sold before Simon stopped making turntables, 'got out' of the industry like Hales.
Enjoy your music!
