Slowly building a home theatre/jam station according to what I can find on sale online.System is as follows

ioneer VSX 1131 7.2 ch receiver
Polk Tsi 500 speakers for front
2 sets of Polk Monitor 40 Series 2 speakers(one set for speaker b,the other for surround)
2 Polk PSW 10 powered subs
5.1 ch used as receiver supports bi-amping at the cost of "rear" surround inputs.All of this was obtained new for around 800 dollar mark(Receiver discontinued model as well as Polk speakers,215 dollars new on Newegg).I realize that bi-amping is referring to separate amps not integrated like the reciever but I have a chance at getting another VSX 1131 new for 200 dollars.Would this be worth it to biamp properly(passively)and free up my surround back inputs w/o driving into the expensive world of pre amps,power amps and separate active crossovers?
