Hi, new to the forum, and getting back into the HT life. I had a nice set up a few years back and had to convert the theater room into living space. Recently moved and now have a 30x22 room for a theater again. I'm upgrading some of my speakers and subs as well as projector. My question is the receiver I have is Onkyo SR875 and with all the 4K talk now I thought I should upgrade. When I saw what my Onkyo was selling for now I was very discouraged seeing as how I paid 1600 for it. It seems I can get a newer version pretty equivalent for half that price. One I was considering was Denon x4100w. The thing that attracted me to it besides 4k was the sticker on the unit reads 235w per channel. I figured since I was going bigger with speakers this would be great. After reviewing it though I read 125w per channel is the actual rating. My Onkyo is 140w per channel. So my question is, leaving 4K out of the equation and just focusing on power, would this be an upgrade? Should I just keep going with my current unit and wait for prices to come down on higher end 4k models?
