I agree with John about the Venustas. As for internal wiring, I sent my SME V to England* to be fitted with the MCS 150, and it sounds terrific. AFAIK, SME still uses a ribbon in the SME IV, which they claim is best for MC cartridges. Originally the ribbon was made for them by Magnan, now they make their own or source it elsewhere -- you should check with them on that.
If you have a IV, I think you should leave it alone. If you have a V, ask SME if they can install the ribbon in a V, and would that be better with your MC cartridge than the MCS 150.
* IMO it's best to send the arm to the factory, where they'll give it a complete check-up, especially the bearings which only they can do.
Life is all about asking the right questions ;-)
