Am going to use "Kook" to drive four Marschand XP-1 crossover boards, all PCB's will be on the same chassis. Am uncertain as to grounding the preamp to the chassis. I think a ground connection using the input jack for the signal, and a connection from the power ground to the chassis. Your thoughts please!

My personal opinion is that you should keep your audio ground isloated from the chassis and from mains ground.
I like to run the mains ground direct to the chassis, and keep the audio ground seperate. I only tie signal ground to power ground on the secondary side of the transformer, and do not tie the secondary power ground to the chassis ground.
So, for the kook, I would set it up as if it were standalone with no connection from it's ground to the chassis, and connect signal to each X-Over. I woulod ten set up each X-Over if they were standalone (without connecting their signal grounds to the chassis).
Does this answer your question?

Brian thanks for the quick response. If I understand you correctly the only connection to chassis ground is at the mains input and the signal ground "floats through" the stages remaining isolated from the chassis! Yes?

Yes. The Kook ties signal ground to it's power ground, as your x-overs likely do as well. Connecting each of the devices also to the chassis ground would surely result in a ground loop. So, float the signal ground.
