I’m in the “mental discussion phase” of upgrading my TV. I’m considering an LG 86” Nanocell. Since my current TV is not a 4K, I’ll have to also upgrade my A/V receiver. I currently have an older 5.1 Klipsch speaker setup using RF3s for the front speakers, a RC3 for the center, RS3s for the surrounds, and a KSW15 for the subwoofer (I’ll keep these speakers as is for the home theater.). Since my room isn’t really conducive for anything more than a 5.1 setup, I’m looking at an Onkyo SR393 receiver. I was enticed by that receiver because of the literature about the “Vocal Enhancer for Clear Dialog” and the ease of installation. My question is, will the Onkyo SR393 drive the speakers? A second question relates to the HDMI setup, as both the TV and receiver have the new version of HDMI 2.1. Would upgraded HDMI cables be warranted, as I have read in other discussions that the older ones are all that is necessary for now? Lastly, is it possible and would it benefit my home theater if I ran Ethernet hardwire straight from the router to the home theater, and if so, how would one do that? One of my constraints is that I don’t want to spend too much on upgrading the receiver, but if there is a better recommendation, please advise. Thanks for the help.
