Moran tang to all who answered. Very kind. By the sounds of it,
The RS70 and A119 aren't too dissimilar, and the extra money
for the RS70 goes towards your Inverter and Slew.

I take the point that neither is the best sig amp around, but I
don't intend for any signal passing through it to last long in its
pristine state anyway. It is just a means to an end.

Being a tight Jock, however, I can spend an extra 25 quid and
get the 119 and a Wasp filter. Hmm, that sounds tasty!

Anyway, thanks for the advice,
