Rack Gear

What's the best way to set up the following rack mounted gear (in order from guitar to unit 1 through to unit 4):

Mesa Boogie Rectifier Recording Preamp
M-Audio Delta 1010 (rack mounted hardware for the soundcard)
Samson Power Amp (to speakers)
Yamaha SPX1000 (digital effects rack)

I assume the sound card (Delta 1010) is the last piece of hardware which sends the output to the Power Amp and the studio monitors.

This is the way I'd do it....

Guitar-Mesa Boogie Pre-amp-Yamaha SPX1000-Delta 1010.

Are your monitor's active or passive? If the poweramp is for the monitors, you'd still connect it the same way, but add the poweramp after the Delta 1010 to power the monitors..
