Rega arm vs Sumiko


I' m about to have my 20 year old Sota Sapphire with a Sumiko MMT arm updated by Sota and someone has offered a Rega RB 250 arm very reasonably to me. The MMT came with the table when I bought it years ago and performs fine - would the Rega be an upgrade?

IMO the Rega will not be an upgrade. You should look for a SME 309, IV, or V. Any of those would be an upgrade, although probably more expensive than the Rega.
I never noticed the degrade that a detachable headshell supposedly causes,
I used to keep three or four headshells with different carts for different music when I had a nice Sony DD table, lots of fun!
"I never noticed the degrade that a detachable headshell supposedly causes."

Agreed. I've owned hundreds of arms and a lot of them had detachable headshells. I never noticed any degradation either.
The sumiko mdc 800 is the tonearm you want.It is in the super tonearm category,and works very well with sota.A upgraded rega would be a 3rd as good at best.
