I have an older Onkyo receiver that was a part of the home theater in a box that I bought years ago. It is a HT-R330 for reference.
I recently picked up an Asus PN50 and turned it into a streaming PC for video content. Bit, overkill but went that route due to pricing was not much more than other NUC due to deals at Microcenter.
I currently have the PC hooked up to a TV via HDMI in the eARC port and then via toslink out to the Onkyo receiver. Would there be any potential benefit over upgrading the receiver to connect via HDMI instead? I know with an upgraded receiver I could finally integrate a powered sub to the system at least.
