cheers Xoc1 excuse my ignorance in these matters,
The way i have this set up is :
cdp or playonHD! streamer thingy TO Dac TO preamp TO monobloks
so what does the pre do ? does it just pass thru what the work that the dac does onto the amps or does the preamp alter the sound at all ? really sorry for the poor terminology :D

The preamp in your set up is just being used as a buffered volume control,
The preamp probably blocks any DC and RF and ensures that the power amp is driven properly at any volume setting, by driving the signal with a low impedance to minimise losses due to the interconnect cables to the monoblocks.
