The K-nisi page states it all.I simply didn't scroll-down far enough.
The Sigma Drive 990 was released in 1982,followed by the (also) Sigma Drive 1100 and 2200 in 1983.
In 1984 the non-Sigma 1100SD was released.
A further two models the 1100D and the 1100EX(both non Sigma)were released in 1986 and 1987 respectively.
Thus,as I thought with the Kenwood Basic M2(Sigma) and the Kenwood Basic M2A(non Sigma),the Sigma models came first,but were quickly superceded by non-Sigma Models which were almost identical to the first Sigma amps the difference being that the Sigma Drive was dropped.
I looked for the L-08M page on k-nisi.

It states that the Sigma Drive L-08M was released in 1980.
To clear-up why Kenwood took all the options that they did around this time,it would be necessary to have the input of someone who knows the inside story.
