Tonearm suggestions for my Nottingham Analogue Spacedeck


After contemplating purchasing other TT,s I have decided to just upgrade my existing TT, my Nottingham Analogue Spacedeck.

I already use a Walker Motor Controller and it sits on Isoacoustics feet.

I think it's weak link right now is possible the stock Spacearm.

To that end looking for thoughts and suggestions for a good replacement. Using lomc carts right now, Scheu Analog MC SL and have the use of an Ortofon Cadenza Black.

Have looked briefly at Origin Live, Audiomods, Rega etc but have ZERO experience with tonearms apart from whatever has been on any TT I have owned at purchase time ( usually stock).

Not really looking to explore vintage or air bearing arms at this stage.

Thank you.

I have a Graham Engineering Phantom tonearm on my Notingham Dias table. Outstanding performer. Their prices are staggering, however.

May I ask you if you are using Stevenson, Lofgren, or Baerwald alignment when you have the space arm set pivot to spindle at 208mm?
i have a spacedeck and spacearm 1 (black), I never found an ideal set up with it. Thanks.:)
