"My question: is it possible to use the ARC D-90 for the HT front speakers by using a Pre-out from a newer receiver?"
Yes. Sure.
"Any recommendations on receivers with Pre's that could do this?"
Many but one with a great feature set is the Denon AVR-4311ci.
BTW, what does any of this have to do with bi-amping?
Yes. Sure.
