Pre-Amp Pass Through for HT

I have a fairly nice Surround Sound Processor, the old Cal 2500 SSP which delivers very respectable two channel play back. I would like to run some A/B comparisons versus my current pre-amp but since the pre-amp is balanced and the Cal is single ended outputs it requires multiple swithches with wiring configurations to the amplifier. I can use the pass through capability with the pre-amp which brings me to my question. If I am using the pass through function am I receiving any residual sonic benefit from the pre-amp or is it giving me a "true" read on the capabilites of the processor. In this set up the Cal would be input into the preamp and the pre-amp set to pass through. It sounds great this way but I don't know if what I am hearing is all due to the Cal or if the Pre-amp is imparting any sonic signature to what I am hearing as well. Any/all comments/insights are appreciated.

Thanks!

Noble,

Appreciate the response. I performed the exact same test you did with a dual out CD player, and came to the same conclusion you did regarding a noticable difference with going throught he processor & pre-amp, but much more subtle differences when the pre-amp was in pass through mode. Thanks for sharing your perspective. It did help.
