Upgrades to Sota Cosmos IV


Hi all,

My Sota Cosmos IV is currently back at the factory for a service and some upgrades.  I was wondering whether to do the Pump/Power Supply Series VI upgrades and the Eclipse DC motor upgrades. 

Has anyone upgraded their older Cosmos to current specs and did both of these upgrades make any significant difference to its performance? The only upgrade I was contemplating was the platter to the new magnetic revelation platter.

The costs of the upgrades be better spent on a new cartridge?

Thanks
Alan

I recently upgraded the motor and bearing on my Jewel (keep your old platter).  My old motor was having a hard time keeping speed.  The new ones are amazingly precise.  The maglev bearing is dead quiet. However i do have a few reservations.  I had to clean and oil the bearing twice before things settled in.  2 pieces of advice:  1-Don't let Donna talk you into anything.  She will sell you the world.  2-Christian is a great guy and if you have any issues contact him directly.
My table is "dead silent" now.  With a record clamp, there is a chance that groove noise is occurring on your table but I have no clue if my maglev alleviates that.
The maglev also helps to add another layer of isolation between your platter and the room.  It definitely is a shock absorber.  I also added a Townsehn Seizmick Sink.  No noise is getting through from the room.  Before you drop $3k, go listen to a table.
