@spoonman16510 I read that an external preamp can be hooked up to an av receiver, how would I do that??
You have what you need using the 1:3 splitter recommendation and keeping the Pioneer avr out of the mix for many reasons others have suggested.
WHY are you thinking you still need the Pioneer AVR in the mix, and for some other reason you’ve not shred yet here? For what purpose does it still serve?
