You have been sucked into a tortuous path.
By listening to the Klimax in your system, you will not be happy until you have the full Klimax. Therefore you need to map the cheapest path if you want to do it in stages.
The least expensive path is to buy it all up front.
The next least expensive path is to minimise the upgrade steps.
Can I suggest considering -
LP12 + Radical 2 + Keel + Ekos SE2 + Karousel up front.
Use an interim phono ( your current phono ) and get the Urika later.
Otherwise if you want a compact form have a look at the Kuzma R/4Point9 or Kuzma R/4Point11 combo.
Wood plinths are available if you like that look.
Less money and very good performance - an upgrade from your SME - I've heard both.
If you want Klimax performance Kuzma M and 4Point11 combo is excellent - you would need to spend twice the price to get any significant upgrade from that.
