Bi-amp through receiver vs pre out to 2 channel for fronts

what are thoughts on buying an amp first to run from my Elite receiver, and then buying a pre amp with HT passthrough in the future to stick between them?

Wonderful idea! it made subwoofer connection easier too.

on the HT receiver setup menu you need to select front R/L speakers to "Large" and No subwoofer.

On this setup the HT receiver will send the LFE signal to front speakers.The downside of this setup is those small front speakers will operate at full range (Not high passed)!

You can connect the integrated amp pre-out to the subwoofer line in , use the subwoofer's internal low pass filter set to 80Hz to begin with, on the HT receiver setup menu you need to select front R/L speakers to "Large" and No subwoofer.
