First Time Rack Builder - What goes where?

[Hawkwind]

I am building a rack for the first time, so I have some basic questions. So far I have:

ADA MP1 -> Chandler Tube Driver -> TC G-Major -> Budda Power Amp.

The rack dumps into a Genz Benz 212 GFlex run in stereo. A friend of mine is looking to get rid of a BBE 422a with two channels. Where and how does a BBE Sonic Max. get fit into this? Also, I am looking to add a Rocktron hush unit. Where would I put a hush unit?

Just a little confused.

if im thinking correctly about the chandler, it should go before the ada so its a boost going into the preamp. *so the lineup should look like this:

chandler
ada mp-1
bbe
hush
gmajor
budda

there is a slight possibility that the BBE may work ok after the hush, but id bet that youll get better results putting it before
