I need an HDMI board for an Onkyo txnr646. The Integra dtr30.7 is the sister model and shares the same feature set and the same HDMI board part number.
I downloaded the firmware for both units and a file compare says they're identical.
Has anyone tried swapping between sister units and found them compatible ?
