Is this possible with the Connect? If no, what would you reco to make this happen? I've tried the Denon HEOS an Onkyo NR575 to pull this off and neither works in one way or another

Use Tape Out to the connect and then the connect will send whatever is playing on the receiver to any other Sonos speaker in the house.
You can use Tape In to be able to play Sonos music from your Sonos app on the receiver itself and its attached speakers (in combination with Sonos speakers around the house).
Essentially a Sonos Connect makes your receiver completely a Sonos unit.
As far as sync goes when playing Sonos music you should be good - depends on the receiver. If really older and doesn't have all the DSP / Surround processing it probably plays fairly direct and will be in sync with other Sonos speakers. If a little new and has DSP functions etc. hopefully it has a Direct Mode that bypasses all that circuitry in the receiver to keep the sound across the receiver and other Sonos units in house in sync.
But - if play music from source on receiver and Sonos speakers in house then the sonos speakers will have a 70ms delay and be slightly behind your receiver - in this case a dsp mode on receiver delaying its output would be good. As long as not right in same room it won't have to much of a stadium effect.
