My tickover when warm is 900 rpm and this is ideal for "creep" on the auto box. However I have noticed that since fitting a new accumulator sphere that sometimes there is an elongated "hiss" when at the lights and if I give the throttle a slight blip then I get a click from the system and the hiss has gone.
Is an adjustment to the hydraulics necessary? And if so what is it? Or is this considered perfectly normal?

It seems to me that this is perfectly normal.
The pump has to put enough LHM into the sphere to cover the leakages between clicks, leakages which are fairly constant. So, if the time between clicks increases (when you put in a new sphere) the hissing time (ie the time when the LHM is flowing into the sphere) must also increase. Erm,I think anyways...
