The DSP-10 digital signal processor is built in on the ts-950 and is

essentially making it a 950.

I think you have that backwards. The SD model was the same as the base
950S with the DSP installed. The SDX was a later version. There was a
QST review of the SDX that concentrated on the differences. Ones I
remember are DSP installed with some more functions, different types of
final transistors (bipolar vs FET I think), some additional memory
functions. I believe the consensus was that the SDX was a better
receiver but the S/SD is a cleaner transmitter.
